Diagnostics messages
A diagnostics message is generated for each diagnostics event and the DIAG LED on the RQ
4x120VDC-230VAC/5A CO HA flashes red or the MT LED lights up yellow.
The diagnostics messages can be read in the diagnostics buffer of the CPU, for example.
Diagnostic messages are assigned either channel-specific to an output or assigned as module
messages to all outputs. All channels are switched off for diagnostics messages that affect the
entire module. Only the corresponding relay contact is affected by diagnostics messages,
which refer to individual channels.

Only the terminal blocks (TB 45 ...) are suitable for operating I/O modules with IO redundancy.
Maintenance events
A maintenance event is generated for each maintenance required identified. The MT LED
lights up on the module.
