Within the ET 200 family, ET 200M represents the main line of distributed I/O systems for process control applications with SIMATIC PCS 7. SIMATIC ET 200M offers the greatest benefits for complex user-specific automation tasks. The system comprises a wide range of I/O modules based on S7-300 technology, including special control functions. If active bus modules are used, defective peripheral modules can be replaced while the plant is running without affecting neighboring modules. A fast and safe connection of field devices to the I/O modules of the ET 200M remote I/O stations can be made via so-called terminal modules MTA (Marshalled Termination Assemblies). With their help, the effort and costs for cabling and commissioning can be significantly reduced and wiring errors avoided.

With the SIMATIC CFU (Compact Field Unit), the previously very complex integration of field devices is easier than ever. You benefit from greater flexibility and easier handling coupled with maximum availability.

 

Ready for game-changing innovations at the field level? Transfer your familiar plant concept efficiently to the digital world. The compact field distributor is installed at the process level and is connected via PROFINET directly to the process control system to form the foundation for digitalization in the field.

 

The SIMATIC CFU combines a digital fieldbus with conventional I/Os and is suitable for use directly in the field, as far as hazardous zone 2. This significantly reduces the footprint of the entire I/O system: Conventional control cabinets are a thing of the past and significant savings can be made with regard to cables and terminals, as well as in the planning and documentation work. The device reduces the potential for errors during operation, simplifies plant expansions or modernization, and reduces the amount of work required for the hardware FAT.

The PA edition of the SIMATIC CFU combines the ruggedness and simplified handling of the PROFIBUS PA communication standard with all the advantages of the PROFINET standard based on Industrial Ethernet. This compact hardware innovation automatically initializes connected field devices and integrates them into the process control system. What used to take 30 minutes is now done in less than one minute. That's Plug-and-Produce!

Distributed I/O, transmitters, drives, valves or operator terminals communicate with the automation systems at field level through a powerful real-time bus system. This field communication is characterized on the one hand by the cyclic transmission of process data and, on the other hand, by the exception-based transmission of alarms, parameters and diagnostic data. The universal PROFIBUS covers all of the requirements of the production and process industries and has already proven itself as a rugged and reliable communication medium at the field level.

 

Process engineering processes are often executed in corrosive, harmful and hazardous environments. Therefore the direct connection of transmitters and actuators, including power supply via the communication medium, as well as detailed diagnostics, is particularly relevant to the automation system. Both PROFIBUS PA and FOUNDATION Fieldbus are suitable for these requirements. Both standards can be integrated seamlessly in the SIMATIC PCS 7 process control system using PROFIBUS DP as a link.

To create a smooth network transition between PROFIBUS DP and PROFIBUS PA, the SIMATIC product range offers two versions: the DP/PA coupler and the PA link. 

 

  • The DP/PA coupler is especially suitable for small quantities of signals and low timing requirements.
  • The DP/PA link is ideal for a large number of stations and high cycle time requirements

The network transition between PROFIBUS DP and FOUNDATION Fieldbus is implemented with Compact FF Links. The Compact FF Link can be operated individually or redundantly.

With conventional fieldbus installations, changes during runtime are only possible to a very limited extent. This is because short-circuits or contact bounces when connecting or replacing devices can lead to the failure of the fieldbus segment.  Fieldbus installations with active field distributors from SIMATIC permit the addition and removal of field devices and of active field distributors during operation without any disrpution.

 

The active field distributors (AFD) can be operated in environments up to Zone 22 and are available in different versions.

SIMATIC AFD4 / AFD8

Each AFD4 model can hold up to four, and each AFD8 can hold up to eight standard-compliant field devices in a fieldbus segment with automatic bus termination.

AFDiSD (Zone 1)

AFDiSD (Active field distributors intrinsically-safe with extended fieldbus diagnostics for PROFIBUS PA segments) can be operated in environments according to hazardous zones 1/21 and 2/22. AFDiSDs can integrate up to six standard-compliant, intrinsically-safe field devices in a fieldbus segment via its intrinsically-safe, short-circuit proof spur line connections.
