System configuration in RUN (CiR)

4.13.1

System modification in a non-redundant system

Properties
There are plants that must not be closed down while they are running. This may be due to the
complexity of the automated process or because of the costs involved in restarting. A
modification or removal of system components may nonetheless be necessary.
Certain system configurations and parameters can be modified in RUN by means of the CiR
function. To make the modifications, the process is halted for a brief time. The process inputs
retain their last value during this time period.
The configuration of the ET 200iSP can be changed with CiR during operation.
You will find a detailed description of this function and the settings for it in the function manual
Modifying the System during Operation via CiR
view/en/14044916).
What do you have to pay attention to when planning the ET 200iSP stations?
• Set up the ET 200iSP station with terminal modules and termination module.
• Equip the ET 200iSP starting from the interface module with the required electronic modules.
Fill the remaining slots with the reserve modules as far as the terminating module. All the
reserve modules must be inserted and there must be no gaps.
• You must not configure these reserve modules.
Rules for making changes to the system while it is in use
• Replace the reserve modules with the planned electronic modules. Start with the first reserve
module in the lowest slot (to the right of the last electronic module). This may create a gap,
i.e. only replace a reserve module with the electronic module.
• If you have fitted a slot cover on the last free slot, it is not expandable.
• Note that the terminal modules TM-RM/RM are required for the electronic modules 2 DO
Relay UC60V/2A.
