Corrected from:
Cabinet Controller c520 V1.15.1
Cabinet Controller c550 V1.15.1
Behavior of the new version:
If the PLC Runtime or the controller operating system crashes unexpectedly, all outputs of the I/O modules connected to the controller’s backplane bus are setto "0".
Description of the behavior:
The outputs on the controller's backplane freeze.
Conditions under which the behavior occurs:
In very rare cases, e.g., due to a hardware defect, the PLC runtime or the controller operating system may crash. In this case, the outputs of the I/O modules connected to the controller’s backplane bus permanently retain their last set values.
Affected products:
Cabinet Controller c520 V1.15.1
Cabinet Controller c550 V1.15.1
Immediate action, recommendations, assessment:
The probability of this functional limitation occurring is very low. Regardless, the behavior of the outputs must be taken into account when configuring the machine.
