PCS 7 Minimal Configurations

  • Entry
  • Associated product(s)
SIMATIC PCS 7 is a scalable DCS which can be used both in small and large plants. The documentation focuses on the selection of suitable PC constellations for small plants and minimum configurations. The setup and configuration steps for the individual configurations are described in addition.

Purpose of this document
On the PC side, typical PCS 7 stations have at least one ES (Engineering Station), one or several possibly redundant servers, as well as several OS clients (Operator Stations). Apart from the maximum availability of process control and data acquisition, the predominant option here is loading program adjustments or expansions quickly into the running process without any interference.

In comparison, small systems or autarkic units after commissioning tend to work extremely poor regarding maintenance. Reaching a high efficiency there requires being able to work with as few PC stations as possible here. It therefore makes sense to use the rarely used ES as an OS during process mode.

This document is meant as a selection aid during searching for the suitable PC constellations for small plants. Various minimal configurations (up to a maximum of three PCs) are compared regarding their functionality. Since the respective PCS 7 configuration is not a focus of the system documentation, the activities necessary for the setup are given in form of detailed step-by-step instructions.

Main contents
The following points are emphasized:

  • Configuration comparison regarding functionality
  • Activities for engineerrring of the various configurations
  • Expansion of an ES/OS stand-alone system by the PCS 7 Web Option
