3T-NET	Sites
	http://www.3t.nl
	Background
	A network originally developed by the Dutch company 3T. A little bit of public documentation about the protocol is available in the fieldbus technology overview report (1995) of the CME (Centrum voor Mikro-Elektronica, now called Syntens). 3T-Net is a fieldbus protocol that is optimised for 8051 microcontrollers in a multi-master environment. It makes use of the internal UART and an external RS485 transceiver. Communication speed is up to 500 Kbps with a low processor load.

ABUS	No URL known.
	Background
	"Automobile Bitserielle Universelle Schnittstelle" is created by Volkswagen (Germany). It is intended for use in trucks. The network runs at a speed of 500 Kbit/s. Messages consist of 1,5 startbit, 0,5 syncbit, 12 bits identifier, 16 databits, 1 acknowledge bit and 1 stopbit. The first bit of the identifier distinguishes between commands and data. Commands have a higher priority than data. Every node on the network can subscribe to messages with a certain identifier. In this respect ABUS looks very much like CAN. This information is based on an article in the German magazine "ATP", issue 11/94.

BOW-BUS	Sites
	http://3t.nl
	Background
	The "Bow-Bus" is a network especially designed for the Dutch Sparta "E-Bow" bike, which has a integrated electromotor aiding the bicyclist in keeping a high speed with little effort. The bike has an electromotor, battery and a management system with user control panel, connected via a 24V bus and serial network. The Dutch company 3T (3t.nl) developed the protocol called "Bow-bus", for this system, as existing networks (as Profibus, CAN) had too much overhead and were too expensive to implement. This information is based on an article in the Dutch magazine "Bits & Chips", issue Dec. 2001.

CAN CALIBRATION PROTOCOL	User Group
	None known.
	Sites
	http://www.asam.de/documents/MCD.htm
	Background
	CCP was developed by the German Ingenieurburo Helmut Kleinknecht in 1992, a manufacturer of calibration systems for the automotive industry. Later, CCP was taken over by the ASAP working group as a standard protocol for data acquisition and calibration, and enhanced with optional functions. CCP defines a master/slave relation between devices. The master device (host) is a calibration tool or a diagnostic/monitoring tool, or a measurement system initiating the data transfer on CAN by sending commands to slave devices. CCP supports commands for generic control with primitive memory transfers, and for data acquisition. These two parts (function sets) of the communication protocol are independent and may run asynchronously, depending on the implementation in the slave controller.

	Background
	CAN/Open is the name for a protocol which was originally developed by Philips Medical Systems, later taken over by the CAN User's Organisation (CiA) and known as CAL (CAN Application Layer), which evolved further to what is called CAN/Open now. It is one of the many application protocols for CAN, competing with Devicenet and many others.

C-BUS	User Group
	None known.
	Sites
	http://samg.yi.org/clipsal.html
	Background
	The C-Bus system is a fully programmable control system designed primarily to optimise lighting arrangements to save electricity cost. It also provides more flexible and efficient lighting operations compared to conventional lighting systems in multistorey buildings, offices and hotels. C-Bus was developed by Clipsal in South Australia. It uses a twisted pair to carry controls data. The intelligence in the system is distributed along the pair. Each unit in the system (switches, lights, motors TV’s etc.) has its own micro-controller associated. In the case of switches, one, two or four switches/housing, the micro-controller is behind the switch. One micro handles one to four switch buttons. In the case of Fluoro’s, a control unit is housed in the Fluoro housing itself, but in the case of incandescent lamps, a remote unit having a micro and 4 relays (for power switching) is used. There is also a dimming unit available which can be programmed to handle various lights connected to the network. They are currently developing a dimmer unit which can handle 20 Amps. Each control unit draws around 20 ma and power is supplied at 36 volts by small power units capable of 300 ma output. The C-Bus system can address up to 65000 units, but a nominal 100 units is the maximum recommended on any one network. So 100 x 20 = more than one power supply on each network. The system runs at a max. of 3.5 Kbits/sec and this rate is controlled by clocks which are also bridged across the twisted pair. This rate was chosen as being the highest rate usable before terminators would be required on the twisted pair.  More than one lock is used in any network as a safe guard against damage to the pair. So the clocks are distributed along the pair also. The maximum length permitted for a pair on any one network is 1 km. Networks can and are interconnected using a network bridge. This unit accepts incoming data on one side, transfers it to the other side, verifies that the transfer is successful and only then outputs the data to the new network. It’s a bit slow but it works. A maximum of 7 networks should be interconnected otherwise the propagation delay becomes too long.

C-FIELDBUS	Sites

	Mailing list
	There are two mailing lists; the first at http://groups.yahoo.com/group/CANbus (this is the well-known Vector mailing list, name="CANbus_2002", password="password"), and the second is at www.can-cia.de/board.htm
	Background
	CAN is only a small part of a complete network protocolstack. Since there was no standard-setting organisation or company during the early 90's, many companies developed their own and this is the reason why there are about three dozen incompatible protocols, such as: CAN/Open, DeviceNet, CAN Kingdom, SDS, SeleCAN, CAL, M3S, LBS, etc.

	http://www.philips.de/licht/oem_setmakers/technik/dali/dali.htm http://www.lampsandgear.philips.com/press11.shtml
	Background
	DALI is a development of the companies Helvar, Huco, Philips, Osram, Tridonic, Trilux and Vossloh-Schwabe. It is a standard for a communications protocol for control of electronic lighting ballasts (dimming controls). It is designed exclusively for lighting purposes, and meets specific needs that are not satisfied by more complex bus systems. A DALI system consists of up to 64 ballasts connected along a twisted-pair cable, and a DALI controller. Maximum network size is 300 meter, and thus suitable for mid-size rooms and standalone systems. Sixty-four unique ballasts can be identified, and sixteen groups of ballasts. DALI messages consist of 1 start bit, 8 address bits, 8 databits, and 2 stopbits. A reply consists of 1 startbit, 8 databits, and 2 stopbits. Typical network commands are "Set light level", "Go to minimum level", "Turn lamp off", "Set light at predefined level", "Return light level", and "Return status". Light levels are specified via a logarithmic regulation curve, running from 0.1% to 100%, specified in an 8 bit number. Operating parameters can be changed and stored dynamically in the ballast's memory, i.e. sixteen different light levels, fade time, fade rate, minimum light level, maximum light level, actual light level. Diagnostics include the status of each ballast and lamp.

	Background
	In 1993 CENELEC (European Committee for Electrotechnical Standardization) ordered the working group TC65CX to develop a European fieldbus standard. As usual, no agreement could be reached on which existing systems would become “the” European standard, so a compromise was reached by including several incompatible systems into one standard: the German Profibus (DP and FMS), the Danish P-Net, and the French WorldFIP. In autumn 1995 there was the first voting for the standard. At first the standard was rejected because Finland, Ireland, Norway, Sweden and the United Kingdom voted against it. In March 1996 there was a second round of voting and the rules for standardisation were changed so that to get a fieldbus standard accepted only 51% of countries would have to vote yes (18 countries). This gave those three fieldbuses an opportunity to become a standard even if 17 countries voted against them. The standard became accepted in December 1996. Attempts of other fieldbus systems (such as Interbus) to get incorporated in the EN 50170 failed, and this led to several other EN-standards. Later, ControlNet and Foundation Fieldbus were added to the standard, allegedly to thank the US for their support of including Profibus in the IEC 61158 standard.

	Background
	EtherCAT is a new industrial Ethernet protocol developed by the German company Beckhoff. What makes it stand out from its competitors is the very efficient use of Ethernet, because with one telegram many devices can be addressed simultaneous. EtherCAT functions like a huge distributed shared memory, which is completely handled in hardware (via special chips).

The protocol is based on MiniMap, but they are not 100% compatible. In 1992, more than 500 Japanese companies have introduced or announced support for FAIS. Wiring is based on coax, with a maximum length of 1 km. Bitrate is 5 or 10 Mbit/s, with messages containing up to 1 Kbyte data. This information is based on an article in the German magazine "Elektronik", issue 11/1992.

FILBUS	No URL known.
	Background
	Filbus is a development of the company Gespac. It is based on Bitbus, and every node has its own microprocessor with 64 Kbyte RAM, allowing for enough local intelligence to handle I/O, do some data processing, before sending data over the network. Interesting is the way configurationdata is loaded into a node: a second Bitbus network is available for this. When a node is replaced by a new one, its configuration is automatically loaded via the separate network. This has the advantage that the remaining nodes do not see a performance degradation on the first network as long as the configuration data is being transferred. A central configuration-manager nodes is required for this to work.

	Background
	The FND was developed with German goverment funding in 1988, and because of this the German government required its use on public projects. FND is designed to interconnect "islands of automation" (i.e. complete systems) with supervisory computers. It only specifies a common interface to the data network itself, which may be implemented using any, relatively high-speed technology. The protocol specifies in its application layer general data items and functional properties of these data items. The general data items defined in the FND application layer are the point objects, analogue inputs, analogue outputs, digital inputs, digital outputs, setpoints, multi-state inputs and multi-state outputs. Further installation of FND systems is expected to be limited to the extension of existing installations in Germany (source: http://www.esta.org.uk)

FMS

Background

Also known as: IEC 61158 Type 9.

FMS (Fieldbus Messaging Specification) is not an existing fieldbus, but it is a specification for a part of a fieldbus: the application layer (OSI layer 7). FMS is modelled after MAP's MMS (Manufacturing Messaging Specification), but is much leaner and simpler; of MMS's 80+ commands only 37 were copied to FMS, but with far less capabilities. Even so, it is still a large set of commands. The first system that implemented FMS was Profibus (Profibus/FMS), but this never caught on very well because of the lack of performance, and due to the difficulties in configuring a Profibus/FMS system. To address the performance-issue, Profibus/DP was developed, which is completely different from FMS. DP caught on very well, and this made that Profibus/FMS never became a major player in the fieldbus market. Even though, the ideas expressed in FMS are not bad. Therefore, FMS has reappareared in Foundation Fieldbus. A simplified (15 commands) version is also part of Interbus, where it was originally called "PMS" (Phoenix Messaging Specification). FMS appeared in the original (January 2000) IEC 61158 standard as part of Foundation Fieldbus (Type 1), and no longer as part of Profibus (Type 3), which did not attempt to include Profibus/FMS in the standard (only DP and PA appeared). In order not to have multiple copies of the FMS specification in the IEC 61158 standard, it was decided that it would be extracted from Foundation Fieldbus, and it is now the "Type 9" in that standard. Any fieldbus system which uses FMS can now simply refer to FMS' own chapter.

HOMEBUS	No URL known.
	Background
	Homebus (HBS) is a Japanese standard for use in home automation applications. It has been developed by the EIAJ/REEE (EIA Japan, Radio Engineering & Electronics Association) and was ready in 1988. The standard describes the "network outlets" by defining OSI-layers 1, 2, 3 and 7. Wiring is coax and UTP, running at a speed of 9.6 Kbit/s. When coax is used, the cable can be used simultaneously for transfer of video and audio signals. Gateways to the 220V net and the Philips D2B (for control of audio-visual appliances) are available. More information about this system can be found in the "IEEE Transactions on Consumer Electronics" of 1988, 1989 and 1990.

ISP	No URL known.
	Background
	ISP "Interoperable Systems Project" is a fieldbus which no longer exists. It was an initiative of the companies Fisher Controls, Rosemount, Siemens and Yokogawa as a reaction on the foundation of WorldFIP. The purpose of ISP was to develop a fieldbus for use in process applications, based on the ISA SP50 standard. However, this standard was moving into a direction (FIP) not wanted by the ISP members, who'd rather use Profibus as base. In 1994, the ISP consortium was dissolved, and the member companies joined the Fieldbus Foundation, where the battles continued. The ISP consortium has been a major boost for Profibus outside Germany. Several of the features of ISP went into Profibus/PA. Recently, another ISP feature became part of Profibus/DP-V2.

	Background
	European automakers Audi, BMW, DaimlerChrysler, Volvo and Volkswagen together with Motorola and Volcano Communications Technologies are the creaters of the low-cost, low-speed network bus called LIN. It is used for simple on-off devices such as car seats, door locks, sun roofs, rain sensors, HVAC flaps, cruise control, windshield wipers and mirrors, and other simple applications. LIN is much simpler than other car bus systems (such as CAN), for example one signal wire instead of two; no on-board voltage regulator, a simple electrical interfaces, and cheap microcontrollers. CAN buses are too costly for wide acceptance in noncritical applications, such as door locks and power windows. Therefore, many vehicles still use discrete point-to-point wiring to connect door locks, power windows and other simple devices to microcontrollers, costing up to hundreds of feet of wiring in thick bundles within the doors and chassis. LIN operates at 20 Kbits/s, which gives sufficient performance for the non-realtime applications where it doesn't matter if the information comes 50 milliseconds sooner or later. Each LIN bus will consist of a maximum of 16 nodes-one master and 15 slaves. Because the bus incorporates a synchronization mechanism for the slave nodes, no crystal resonator or clock source will be needed. That means that the microcontroller circuit board can be simpler and less costly. Power for the single-wire bus comes from the car's 12-volt battery. (source: EE Times)

	Project MOFDI will develop and test the next generation of high speed radio connections for Fieldbuses. This significant market need is growing rapidly in importance as industrial users rely on fewer staff to cover larger areas of responsibility in their sites. Also, to save on time and access problems, Fieldbus solutions are needed to support on-line access to all field devices distributed within a plant site, including those on moving equipment and transport vehicles. The key technical feature of project MOFDI is high speed radio data communication for industrial Sensors, Actuators and Operator Interfaces. MOFDI will extend industrial Fieldbus solutions by addition of secure local connections to mobile devices which are otherwise not available for real-time data access and control.

	Background
	PACTWare is not a fieldbus, but a consortium of (German) companies headed by Pepperl & Fuchs. Its goal is to develop a (Windows-based) software-tool using the FDT (Field Device Tool) and the associated DTM's (Device Type Managers), for those systems where a DCS is not used. Basically it is an application framework, in which individual DTM's can be connected and executed, as if it were a single software application. This allows a clear distinction between network device functions, service functions, and asset management functions (trend curve, value monitoring, etc.) via yet other plug-in software modules. It allows device manufacturers to encapsulate and control their devices via a DTM, without having to reveal their device-secrets to other companies, while still allowing their device to be used by system vendors. The PACTWare software was developed by Pepperl & Fuchs, and can be downloaded from the website after signing the P&F Open Source License.

The protocol prevents collisions, by assigning every participant on the network a time-slot which it may use for communication purposes. One station in the network is configured as "Manager", all others are "Controllers". Only the manager can send messages at will; but controllers only when requested by the master. The manager operates cyclically isochronous (time-controlled according to the new IEEE-1588 standard for high-accuracy time synchronization). A synchronisation signal is sent at fixed intervals. All other participants on the network asjust their internal tasks to this signal; this allows time-controlled actions with an accuracy of a microsecond. A total number of 254 participants can be operated on one Powerlink network; this will take about 9 milliseconds. Due to the lack of collisions, Powerlink networks can be larger than traditional Ethernet networks; up to 9 hubs can be connected serially. The "Zurcher Hochschule Winterthur" (ZHW) (Polytechnic Winterthur) in Switzerland is contracted to provide an 'open' reference implementation.

PPCCOM	No URL known.
	Background
	A network for communication between modules of the "PC20" and "P8" family of PLC's created by the department "Industrial Automation Systems" (IAS) of the Dutch company Philips. There are several versions of PPCCOM in existance, a nibble-based version (PC20) and a byte-based version (P8). The download of programs to these PLC's is also done via PPCCOM, but with a proprietary extension. The protocol is master/slave based, with up to 16 slaves. The cabling is a 4-wire RS485 bus, or RS232. The highest bitrate is 38.4 Kbit/s. The PPCCOM protocol is also used as an application layer for the P8 Ethernet controller, in combination with the PDS-7 programming package. It can also be used for communication between PLC's because a mapping was made from IEC-61131/5 style functionblocks to PPCCOM messages. In 1997, IAS was sold off and became Nyquist, which in turn was acquired by Bosch in 2006.

PROFINET	See Profibus
Also known as: IEC 61158 Type 10, IEC 61784-2 Ed. 1, IEC 62411, SEMI E54.13.	Background
	ProfiNet is the next member of the Profibus-family of protocols. It is an industrial Ethernet based system, to which a "proxy" module must be connected which in turn communicates with a Profibus/DP or /PA system. As of the end of 2005, the actual version 3 is the long-expected high-speed motion version of ProfiNet. The ProfiNet specification is given in Type 10 of the IEC 61158 standard, or IEC 62411 (for the I/O version of Profinet only). The specification heavily relies on Microsoft COM/DCOM technology, except for the real-time I/O version which directly uses Ethernet frames and bypasses all protocol stacks; a special switch is necessary in order to reach the highest advertised speed. In contrast to a statement made during a press conference at the end of 2000, where it was said that ProfiNet will be "open source", the source code is actually only available for members of the Profibus User's Group.

	Background
	SeleCAN is a development of the Swiss company Selectron. As its name implies, it is based on CAN. The network is intended for remote I/O applications, and developed around 1995. At that time, there was no standardised open CAN application protocol (we now have CAN/Open, Devicenet and SDS) and that led Selectron to develop its own application layer. The protocol is quite simple, and has very little overhead because of clever use of the CAN message-identifier. Each I/O module can have 8 bytes (64 bits) of inputs and 8 bytes of outputs. Additionally, several commands are available to control each I/O module; this uses the first two bytes of the CAN data for selection of the command, with 6 bytes remaining for parameters of the command. Selectron also allowed download of programs to its own PLC's with later versions of the protocol. A network supports up to 31 I/O nodes, on bitrates of 1000, 500, 100 and 20 Kbit/s. Wiring is according to ISO-11898 as is standard in many CAN networks. The SeleCAN protocol has also been used by various other CAN-based remote I/O vendors, such as Festo, Philips and OmniRay. As of 1997, the SeleCAN protocol seems to have been dropped in favor of CAN/Open. In case you require a protocol description, it can still (1/2004) be found on the Selectron website (URL see above).

SEMI E54.1	Sites
Also known as: SAN, Sensor-Actuator Network	http://www.semi.org
	Background
	This specification provides the structure of SEMI's Sensor/Actuator Network (SAN) standard. It provides the definition for interoperability with respect to SEMI SAN standard-compliant Sensor/Actuator devices. This standard specifies how devices interoperate on a network as part of the control system for equipment. This specification, which is the root of the SAN standard, defines the relationships of each of the other specifications which are components of the SEMI SAN standard. This standard defines a model comprised of device objects which are common to all devices on a semiconductor equipment sensor/actuator communications network. This document describes common device structure and behavior (i.e., the minimum data structure and behavior all devices must support to operate on the network). These devices may range from simple sensors and actuators through hosts, masters, or controllers. The model specified in this document is used in conjunction with a sensor/actuator network specific device model which describes the data structure and behavior characteristic of the specific device. Together, these two models are sufficient to completely describe a device as it appears from the network interface. This standard, together with a sensor/actuator network interoperability guideline, a sensor/actuator network communication specification (see below: E54-4 and further), and one or more specific device model specifications, form a complete interoperability specification. To comply with this standard, a device must implement and support instances of the objects, object attributes, object services, and object behaviors identified in this document, unless explicitly stated otherwise (source: SEMI website).

SEMI E54.4	See Devicenet
Formerly known as E59.	Background
	This standard defines a communication specification based on the DeviceNet protocol to enable communications between intelligent devices on a sensor/actuator network (SAN) that operate according to SEMI specified device models (common and device specific) in a semiconductor manufacturing tool. DeviceNet provides for networking between simple industrial devices (e.g., sensors and actuators) and higher level devices such as controllers. This document enables communications between intelligent devices on a SEMI compliant SAN by providing a presentation mapping of common and specific device network visible structure and behavior to a DeviceNet network. This document specifies the protocol and services that compliant intelligent devices must support to interchange information over this semiconductor equipment sensor/actuator network. This document specifies the utilization of the DeviceNet protocol to present externally visible device structure and behavior, specified in the Common Device Model (CDM) and appropriate Specific Device Models (SDM's), on a DeviceNet network. (source: SEMI website)

SEMI E54.5	See Smart Distributed System
Formerly known as E60.	Background
	This standard defines a communication protocol based on the Smart Distributed System (SDS) to enable communications between intelligent devices on a sensor/actuator network (SAN) to be used in semiconductor manufacturing equipment. This document specifies a SAN communications standard based on the Smart Distributed System (SDS) specification that is in compliance with the SEMI SAN Common Device Model specification. This document specifies the protocol and services that compliant intelligent devices must support to interchange information over this semiconductor equipment sensor/actuator network. (source: SEMI website)

SEMI E54.6	See Local Operating Network
Formerly known as E61.	Background
	This standard defines a communication specification based on the LonWorks technology specification to enable communications between intelligent devices on a sensor/actuator network (SAN) that operate according to SEMI specified device models (common and device specific) in a semiconductor manufacturing tool. This document specifies a mapping of the SEMI common device model (CDM) onto LonWorks technology using the LonMark Interoperability Guidelines established for LonWorks devices. The LonMark Interoperability Association may incorporate into the Interoperability Guidelines any enhancements presented in this document. The SEMI standard for LonWorks is based on the LonMark interoperability guidelines, which provide a framework for interoperable use of the LonTalk Protocol at layers 1-6, as well as at the application layer. Where the LonMark interoperability guidelines do not provide the functionality required by the SEMI CDM, the guidelines are extended with SEMI-specific requirements. This document specifies a SAN communications standard based on the LonWorks specification, that enables communication with SAN devices configured according to the SEMI SAN Common Device Model and appropriate Specific Device Model (SDM) specifications. This document specifies the use of LonWorks technology for services that compliant intelligent devices must support in order to exchange information over this semiconductor equipment sensor/actuator network. (source: SEMI website)

SEMI E54.7	See Seriplex
	Background
	This standard defines a communication specification based on the Seriplex protocol to enable communications between intelligent devices on a sensor/actuator network (SAN) that operate according to SEMI specified device models (common and device specific) in a semiconductor manufacturing tool. This document enables communications between intelligent devices on a SEMI compliant SAN by providing a presentation mapping of common and specific device network visible structure and behavior to a Seriplex network. This document specifies the protocol and services that compliant intelligent devices must support to exchange information over this semiconductor equipment sensor/actuator network. This document specifies the utilization of the Seriplex protocol to present externally visible device structure and behavior, specified in the Common Device Model (CDM) and appropriate Specific Device Models (SDMs), on a Seriplex network. This document is used in conjunction with a SEMI standard SAN Common Device Model specification, one or more SEMI standard Specific Device Model (SDM) specifications (e.g. for a mass flow controller) and the Seriplex Standard Specification. Together, they describe the Seriplex protocol, the externally visible data structures and behaviors of devices utilizing the Seriplex networking capability in a SEMI compliant SAN system. (source: SEMI website)

SEMI E54.8	See Profibus/DP
	Background
	This specification is part of the SEMI Sensor/Actuator Network (SAN) suite of standards and defines a specific communications protocol based on the PROFIBUS-DP standard. This standard, taken together with the SEMI Sensor/Actuator Network standard suite and the PROFIBUS standard completely and unambiguously defines an open standard providing an industry specific solution to off-the-shelf interoperability of networked devices in semiconductor manufacturing equipment. This document specifies a SAN communications standard based on the PROFIBUS-DP specification that is in compliance with SEMI E54.1. As such, it specifies the protocol, services, and behavior that compliant intelligent devices must support in order to interchange information over this SAN in a method compatible with SEMI E39. In conjunction with a SEMI standard SAN Common Device Model (CDM) specification and one or more SEMI standard Specific Device Model (SDM) specifications (e.g., for a mass flow controller), this standard with the related PROFIBUS-DP standard describe the data structures, interactions, and behavior that are characteristic of the various devices on the network. This composite model forms a complete interoperability standard for communications among intelligent sensors, actuators, and controllers in semiconductor manufacturing equipment. (source: SEMI website)

SEMI E54.9	See Modbus/TCP
	Background
	This standard defines a communication specification based on the Modbus/TCP protocol over a TCP/IP network to enable communications between intelligent devices on a sensor/actuator network (SAN) that operate according to SEMI specified device models (common and device specific) in a semiconductor manufacturing tool. This document enables communications between intelligent devices on a SEMI compliant SAN by providing a presentation mapping of common and specific device network visible structure and behavior to Modbus/TCP over a TCP/IP network. This document specifies the protocol and services that compliant intelligent devices must support to exchange information over this semiconductor equipment sensor/actuator network. This document specifies the utilization of the Modbus/TCP protocol to present externally visible device structure and behavior, specified in the Common Device Model (CDM) and appropriate Specific Device Models (SDMs), for the Modbus/TCP protocol over a TCP/IP network. This document is used in conjunction with a SEMI standard SAN Common Device Model specification, one or more SEMI standard Specific Device Model (SDM) specifications (e.g., for a mass flow device), the Modicon Modbus Protocol Reference Guide and the Open Modbus/TCP Specification. Together, they describe the Modbus/TCP protocol, the externally visible data structures and behaviors of devices utilizing the Modbus/TCP networking capability in a SEMI compliant SAN system. (source: SEMI website)

SEMI E54.12	See CC-Link
	Background
	This specification is part of the SEMI Sensor/Actuator Network (SAN) suite of standards and defines a specific communications protocol based on the CC-Link standard. This standard, taken together with SEMI E54.1 and the CC-Link standard completely and unambiguously defines an open standard providing an industry specific solution to off-the-shelf interoperability of networked devices in semiconductor manufacturing equipment. This document specifies a SAN communications standard based on the CC-Link specification that is in compliance with SEMI E54.1. As such, it specifies the protocol, services and behavior that compliant intelligent devices must support in order to interchange information over this SAN in a method compatible with SEMI E39. In conjunction with a SEMI standard SAN Common Device Model (CDM) specification and one or more SEMI standard Specific Device Model (SDM) specifications (e.g., for a mass flow controller), this standard with the related CC-Link standard describe the data structures, interactions and behavior that are characteristic of the various devices on the network. This composite model forms a complete interoperability standard for communications among intelligent sensors, actuators and controllers in semiconductor manufacturing equipment.This standard does not purport to address safety issues, if any, associated with its use. It is the responsibility of the users of this standard to establish appropriate safety health practices and determine the applicability or regulatory limitations prior to use. (source: SEMI website)

SIGNALBUS	No URL known.
	Background
	Created by the German company Softing in 1992. It is a network intended for remote I/O applications, with a maximum of 4 Kbit I/O data. Up to 200 nodes can be connected to the network, which uses optical fiber. The bitrate is 2 Mbit/s. There is a master/slave relationship between nodes. Softing is better known for its Profibus developments. The company was later bought by Siemens. The original owners started another company which was again called Softing. It is unclear whether the rights to Signalbus are now property of Siemens or the 'new' Softing.

SINEC L2	No URL known.
	Background
	Sinec L2, the 2nd low-speed fieldbus from Siemens, was created in 1992 as a reaction on the slowness of Profibus/FMS. This protocol was originally intended to be quick enough for remote I/O, but this didn't turn out to be so. Sinec L2 (also called L2/DP) was partially based on existing Profibus technology (FDL) which is the lower layer (OSI Layer 2) only. The L2 specification described how to use FDL in order to create a remote I/O system with it. Actually L2 is quite simple, the specification is only 15 pages A4. Because of the dominance of Siemens in the European market, many other vendors designed their equipment to be L2-compatible. Although L2 was claimed to be "Profibus compatible" the protocol is not compatible with FMS. The lack of support for FMS meant that it never became wide-spread. The L2 protocol gradually evolved into the first version of Profibus/DP, after Siemens started cooperating with the Profibus User's Group (PNO). As of 1993, with the release of Profibus/DP, the L2 protocol quickly disappeared.

	Background
	Created by the Dutch company Positronika in 1984. The network was intended for connecting multiple PDP-11's together for use in automated measuring equipment. In an era where Ethernet hardly existed and IEEE-488 was quite new, Techlan was (too far) ahead of its time because most people had never heard of a "network", and didn't know what to use it for. Techlan was discontinued in 1987; Positronika focussed on LAN's instead which at that time was a booming market. Positronika no longer exists.
