Ways to identify which hardware is offline

For example: I have a PROFINET I/O Interface module (IM 155-6 PN BA) connected to the PLC, and I want a bit in the PLC to be set when it is offline. I have a PROFINET camera connected to the PLC, and when it is offline, another bit in the PLC should be set. What is the best way to do this? The need to have this in memory is so that external devices can read this discretized information.

DeviceStates: Read module status information in an IO system Depending on the mode given you can read information from the complete IO-system including states of the devices. Parameter MODE You use the MODE parameter to read out status information. You can read out one of the following status information items for the entire PROFINET IO or DP master system: 1: IO devices/DP slaves are configured 2: IO devices/DP slaves are faulty 3: IO devices/DP slaves are disabled 4: IO devices/DP slaves exist 5: IO devices/DP slaves for which a problem has occurred. For example: -Maintenance demanded or recommended -Not accessible -Not available -Error occurred regards sancruz
