Definition of a diagnostic alarm
If the user program is to respond to an internal or external error, you can set the parameters
for a diagnostic alarm that will interrupt the cyclical program of the SIMOTION device.
Events triggering a diagnostic alarm
The criteria (events) that trigger diagnostic alarms in a SIMOTION system are the same as in
a SIMATIC system.
For a more detailed description, refer to SIMATIC manual
"Diagnostics" chapter.
Responses to a diagnostic alarm
If a diagnostic alarm occurs, the following take place:
● Diagnostic data are written to TSI#details variable in the Taskstartinfo of
PeripheralFaultTask.
● In the PeripheralFaultTask, you can read out and save the 4 bytes of diagnostic data.
● The group error LED (SF) of the serial interface module illuminates. The group error LED
(SF) is extinguished as soon as the error has been remedied.
