5.2 Interrupts
The digital output module DQ 8x24VDC/2A HF supports diagnostic interrupts and
maintenance interrupts.
You can find detailed information on the error event in the error organization block with the
"RALRM" instruction (read additional interrupt info) and in the STEP 7 online help.
Diagnostic interrupt
The module generates a diagnostic interrupt at the following events:
● No supply voltage L+
● Short circuit to ground
● Parameter assignment error
Maintenance interrupt
The module generates a maintenance interrupt at the following events:
● Limit value warninghe module. The diagnostics alarms can be read out in the diagnostics buffer of the CPU, for
example. You can evaluate the error codes with the user program.
If the module is operated distributed with PROFIBUS DP in an ET 200MP system, you have
the option to read out diagnostics data with the instruction RDREC or RD_REC using data
record 0 and 1. The structure of the data records is available on the in the "Manual
for interface module IM 155-5 DP ST (6E155-5BA00-0AB0)".Short-circuit or overload at the channel
Check the wiring/actuator. Check
the ambient temperature.
Parameter assignment
error
10H ? The module cannot evaluate parameters
for the channel
? Incorrect parameter assignment
Correct the parameter assignment
Load voltage missing 11H Supply voltage L+ of the module is
missing
Connect supply voltage L+ to module/channel
Limit value warning 17H The configured limit for switching
cycles has been exceeded.
? Replace actuator as a precautionary
measure
? Reset counter with DS131
