SIMATIC ET 200 remote I/O stations for SIMATIC PCS 7 (main SIMATIC ET 200SP HA, SIMATIC CFU PA, SIMATIC ET 200M and SIMATIC ET 200iSP series)
The SIMATIC PCS 7 process control system offers a variety of possibilities for detecting and outputting process signals via sensors and actuators as well as for connecting process I/O to the automation systems:
- Signal and function modules in remote I/O stations on the fieldbus
- PROFIBUS DP (ET 200M, ET 200iSP, ET 200pro)
- PROFINET IO (ET 200SP HA, SIMATIC CFU, ET 200M, ET 200SP)
- Analog and digital I/O modules of the SIMATIC S7-400 operated centrally in the automation system
SIMATIC S7-400 signal modules used centrally in the automation system are suitable for small applications or plants with few remote locations. In practice, however, distributed process I/Os are mainly used which, depending on the type, also support redundant configurations or operation in explosive gas/dust atmospheres:
- SIMATIC ET 200 remote I/Os in conjunction with classic field/process devices and HART field devices
- Intelligent field/process devices for direct fieldbus connection
Especially convincing arguments for distributed process I/O include:
- Modularity and consistency
- Flexible adaptability to the plant structure
- Minimum cabling and engineering requirements
- Low commissioning, service and life cycle costs
- Wide technical bandwidth

Integration of process I/O in the hazardous area
G_PCS7_XX_00635
Process I/O in explosive gas and dust atmospheres
The figure shows the possible applications for the SIMATIC PCS 7 process I/O with consideration of different ambient conditions.
Field devices on the PROFIBUS PA or FOUNDATION Fieldbus H1
Field devices located in Ex zones 0, 1, 2, 20, 21 or 22 can be integrated in SIMATIC PCS 7 via various active field distributors on the PROFIBUS PA or FOUNDATION Fieldbus H1. The active field distributor AFDiSD is required for field devices in Ex zones 0, 1, 20 or 21.
ET 200iSP distributed I/O
ET 200iSP remote I/O stations suitable for gas/dust atmospheres can be installed directly in the Ex zones 1, 2, 21 or 22 as well as in non-hazardous areas. The intrinsically-safe sensors, actuators and HART field devices can also be located in zone 0 or 20 if necessary.
ET 200M, ET 200SP und ET 200SP HA distributed I/O
ET 200M, ET 200SP und ET 200SP HA remote I/O stations can be used in Ex zone 2 as well as in non-hazardous areas. The actuators/sensors can also be positioned in Ex zone 1 or 21. Special Ex I/O modules are available for this in the ET 200M product range.
ET 200pro distributed I/O
ET 200pro remote I/O stations are designed for use in non-hazardous areas.
Intrinsically-safe operator panel
An intrinsically-safe operator panel can be used in hazardous areas, zone 1, 2, 21 or 22, if required. For further information on this operator panel, see under SIMATIC HMI Thin Client Ex in the Catalog "Add-ons for the SIMATIC PCS 7 process control system", Section "Operator control and monitoring".
