A.3 Diagnostics messages and maintenance events
The following figure shows the configuration of the channel parameters for data record 128.
x = 12 + (channel number * 2); with channel number 0...3
Any unused bits and bits or bytes marked with "reserved" must be set to zero. Activate a channel
parameter by setting the corresponding bit to "1" or to the appropriate value.

Diagnostics messages and maintenance events

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.

Module Firmware update is currently in pro‐
gress or has been canceled. The mod‐
ule does not output any process or
substitute values in this state.
