5.2 Diagnostic alarms
Diagnostic alarms
The diagnostics are displayed as plain text in STEP 7 (TIA Portal) in the online and
diagnostics view. You can evaluate the error codes with the user program. The respective
channel number is shown for each diagnostic information.
The following diagnostics can be signaled:

Digital outputs DQ0.0, DQ0.1, DQ1.0 and DQ1.1 have shared diagnostics. Digital outputs DQ2.0, DQ2.1, DQ3.0 and
1
DQ3.1 have shared diagnostics.
Diagnostics for short-circuit and overload are effective only for 24 V outputs and only up to an output frequency of ap-
2
proximately 100 Hz. The module is otherwise protected from irrevocable damage caused by short-circuit at the outputs,
and the diagnostic alarm is not displayed.
Cross-channel diagnostics of the digital outputs
The digital outputs of channels 0 and 1 as well as channels 2 and 3 have shared
diagnostics. As a result, when there is an error at one digital output, faults are automatically
signaled for
Ensure that this fault scenario is taken into consideration when using multiple channels.
