5.2 Plant changes in runtime
changes
Adding or removing mod‐
ules components in distrib‐
uted I/O modules
Changing the parameters
settings for a module
Additional information
You can find detailed, step-by-step instructions on the procedure for plant changes in runtime
in the manual
Note
Note the following information:
● The procedures described for PCS 7 can be found in the
Fault-tolerant Systems manual, "Modifying the System During Operation" section.
● Make sure that all systems are free from faults and that the H-system is operating
redundantly and without errors after any modification to the plant.
● If you violate one or more rules in this procedure, the fault-tolerant system may respond in
ways that restrict its availability, up to and including failure of the entire process control
system.
The following table is an overview of the descriptions. The procedures described for making
changes in runtime assume that the system is designed redundantly and that your aim is to
achieve this again.
