Alarm processing

6.2 Diagnostic alarms

Detailed information on DP slave diagnostics can be found in the SIMATIC Manual titled
ET 200S Distributed I/O System .
Alarm evaluation
Alarms sent by the I/O are evaluated in the PeripheralFaultTask. When the
PeripheralFaultTask is started, the Taskstartinfo is made available; you must evaluate this in
the user program. To do this, assign a program to the PeripheralFaultTask in the execution
system (see sample program Unit_E_FC_ctr).
The Taskstartinfo of PeripheralFaultTask is comparable to the local data of OB 82 in the
SIMATIC system.

Diagnostic alarms
Diagnostic alarms enable operational messages (hardware faults) of the ET 200S FC to be
detected in the SIMOTION device.
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 program execution in the SIMOTION device.
Events that trigger a diagnostic alarm
The criteria (events) for triggering diagnostic alarms in a SIMOTION system correspond to
those in a SIMATIC system.

interrupt (DAL) was caused by an input range on the module, oth‐
erwise _SC_INVALID_ADDRESS
TSI#logBaseAdrOut
Logical start address if a hardware interrupt (PRAL) or a diagnostic
interrupt (DAL) was caused by an output range on the module, oth‐
erwise _SC_INVALID_ADDRESS
TSI#logDiagAdr
Diagnostic address of a DP slave if the interrupt was caused by a
CPU stop or recovery of the associated DP slave, otherwise
_SC_INVALID_ADDRESS
