System configuration in RUN (CiR)
3.12.1
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 modified during operation with CiR.
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 (
http://support.automation.siemens.com/WW/
).
What points should you note when planning the ET 200iSP stations?
● Construct the ET 200iSP station entirely using terminal modules and a terminating module.
● Add components to the ET 200iSP outwards from the interface module, starting with the
necessary 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 terminal modules TM-RM/RM are required for electronic modules 2DO Relay
UC60V/2A.
