● If you have enabled configuration control, the HCS is not ready for operation without a
control data record. As long as no valid control data record has been transferred, the I/O
modules are considered as failed by the CPU and exhibit substitute value behavior. The
CIM continues to be in data exchange.
● The control data record is stored retentively in the CIM. Note:
– If there have been no changes to the configuration, you do not need to rewrite the
– If you write a control data record with modified configuration to the CIM, it will result in
