The comprehensive module range with uniform handling for configuration, assembly and programming allows the SIMATIC ET 200S to be used as a universal I/O system. The finely scalable design permits fast and optimal adaptation to the requirements of the automation task:

• No reserves
• No unnecessary channels

Even if requirements change frequently, setup times can be reduced significantly by replacing or combining different I/O modules.

The transmission rate of up to 12 Mbit/s with PROFIBUS DP and 100 Mbit/s with PROFINET IO as well as the powerful internal data transmission makes the SIMATIC ET 200S also perfectly suited for extremely time-critical applications such as highly dynamic hydraulic applications with position and pressure control.

In combination with the interface module

• IM 151?1 High Feature (PROFIBUS) or
• IM 151?3 PN High Speed (PROFINET)

signal states can be synchronously acquired or output over the isochronous PROFIBUS DP or over PROFINET IO with IRT at precisely defined points in time. Isochronous mode is supported by selected I/O modules (see SIMATIC S7?300 I/O or SIMATIC ET 200S manual). It is possible to combine isochronous and non-isochronous modules in a single station.

In addition to Interface Modules for connecting the SIMATIC ET 200S to PROFIBUS DP or PROFINET IO (either electrical or optical interface) for distributed automation tasks, an Interface Module with an integrated CPU is also available. The maintenance free CPU (without battery) integrated in the Interface Module is based on the SIMATIC S7?300 CPU 314 and is programmed with STEP 7. The CPU permits distributed on-site preprocessing of process data and communicates with the higherlevel motion control system as a PROFIBUS DP slave or PROFINET IO Device.

Two different variants are available for integrating safety technology with SIMATIC ET 200S:

• Over local safety components in motor starter applications
• Over PROFIsafe components that replace the wiring-based safety logic with a freely programmable controller (up to SIL 3 according to IEC 61508 and Category 4 according to EN 954?1).

The construction of the SIMATIC ET 200S allows it to be used under increased mechanical load. The system features support high machine availability requirements.
