● Ensure that your hardware meets the requirements for PCS 7. You can find more
information in the documentation
Released Modules . If system components are not suitable for the updated version of PCS
7, you must replace them. In some cases, you must adapt or redo the configuration of the
components that have been replaced in the updated project.
● You need upgrade license keys to update PCS 7:
– V7.1 -> V8.0 (additional upgrade license key required)
– V8.x -> V8.2
● The automation system can remain in the RUN state during a software update without
utilization of the new functions. The process can be continued. Program changes can be
downloaded during operation. Functions that require a new library version (for example,
SIMATIC Route Control) require a STOP of the automation system.
● The manual contains some sections that are not listed in the overview. Observe the
information provided in these sections when updating the software and check whether this
information is relevant to your PCS 7 system.
● You do not need any new hardware or firmware for your automation system.
● You want to perform the software update without a great deal of configuration effort.
● The process can always be operator-controlled and monitored, if you use redundant OS
servers and update the software accordingly.
