PCS 7 Cybersecurity Blueprint For Water Plants


As a distinctly open system, SIMATIC PCS 7 can be flexibly adapted to a wide range of customer needs. The system software provides the configuration engineer with a great deal of freedom in terms of project configuration, as well as in the design of the program and visualization.

Experience has shown that subsequent modernization or plant expansion work is made much easier if the project is configured "in conformance with PCS 7" as far as possible right from the start. This means users must adhere to certain basic rules to ensure that the provided system functions will offer optimum usability in the future.
This manual serves as a compendium in addition to the product documentation for SIMATIC PCS 7. The basic steps for project creation and parameter assignment are described in the form of instructions. Please refer also to the SIOS portal (section 17.2)

This documentation is intended to help system integrators to setup a water plant more securely.

The guideline directly reflects the recommended method for configuration (defense-in-depth concept in accordance with IEC 62443), which is based on the results of a great deal of practical experience. The description relates to working with the project and the parameter settings of the components it contains but not the application itself.
