Introduction

Introduction
You can find a guide to updating a redundant OS in runtime below. This means that the
operation of the PCS 7 system is not disrupted, the AS does not switch to STOP mode and
the automation process can continue to be operated and monitored.
Requirements
● The redundant OS is made up of the following components:
– Redundant OS server
– OS clients
● The PCS 7 version is at least PCS 7 V7.1.3.
Information on updating the PC stations and project data
You can find information on updating the PC stations and project data in the
System PCS 7; Software Update without Utilization of the New Functions documentation.
Rules
Make sure that you keep to the described order to avoid disrupting operation of the PCS 7
system.
Note
Perform the steps described from Phase 1 to Phase 5 without extended interruptions because
the redundancy is not available during the update.
Note
