Diagnostics messages and maintenance events

Diagnostics messages
A diagnostic message is generated for each diagnostic event and the DIAG LED on the DI
8x230VAC HA flashes red or the MT LED lights up yellow.
The diagnostic messages can be read in the diagnostics buffer of the CPU, for example.
Diagnostic messages are assigned channel-specific to an input or assigned as module
messages to all inputs. All channels are switched off for diagnostic messages that affect the
entire module. Only the corresponding digital input is affected by diagnostic messages, which
refer to individual channels.
