Diagnostic messages of the analog output modules
The table below gives an overview of the diagnostic messages for the analog
output modules.
Table 4-47 Diagnostics Messages of the Analog Output Modules
Diagnostics Message
External auxiliary supply missing
Configuring/parameter assignment
error
Short-circuit to M
Wire-break
Note
A prerequisite for detecting the errors indicated by programmable diagnostic
messages is that you have assigned parameters to the analog module accordingly
in STEP 7.
