Please note
The diagnostic information is only sent to the master sys-
tem when device-related diagnosis is activated in the
switch module. To do this, set switch element 8 of the
8-element DIL switch to “ON”.
When you are commissioning your system, it can in some
cases be useful if you switch off the device-related diagnosis.
If your controller does not start, try the setting “Device-re-
lated diagnosis inactive” on the 8-element DIL switch
(see chapter 3.3.2).
