The CM AS‑i Master ST communication module for ET 200SP enables modular, simple and high-performance expansion of AS‑interface networks via engineering in the TIA Portal.

Up to eight CM AS‑i Master ST units can be plugged into one ET 200SP station with IM 155‑6 PN Standard. The maximum configuration depends on the interface module used.

Multiple masters as well as single masters can thus be implemented in the ET 200SP depending on the number of modules.

Together with the interface module, a scalable PROFINET/AS‑i Link or PROFIBUS/AS‑i Link can be assembled.

Using STEP 7, the AS-i network is consistently configured and programmed with only one configuration tool.

The PRONETA PC program (for ET 200SP with PROFINET interface module) is available for convenient input/output testing during commissioning of an AS‑i network without a CPU; see www.siemens.com/proneta.

For diagnostics during ongoing operation, diagnostics blocks with clearly arranged visualization on the SIMATIC HMI panel are available or can be downloaded free of charge via a web browser, see https://support.industry.siemens.com/cs/ww/en/view/109479103.
