Updating the PCS 7 OS in runtime
Introduction
You have the option of updating a redundant PCS 7 OS configuration at runtime in order to
adapt the "older" version of your current PCS 7 process control system to a "newer" PCS 7
version.
Updating the PCS 7 OS involves the following tasks:
● Preparatory measures
● Installation of the "new" software
● Commissioning measures required to adapt your existing PCS 7 process control system
Updating the PCS 7 OS during running operation offers the following benefits:
● Operation of the PCS 7 system is not disrupted.
● The AS does not enter STOP mode.
● The automation process can still be operator controlled and monitored.
