Operating modes and synchronization
RT classes: RT_Class1, RT_Class2 and RT_Class3 are supported. The device cycle of the position
indicator is not synchronized.
5.1.5
Diagnostics alarms (Alarm CR)
Diagnosis alarms are only transferred, when bit 5 of parameter 00FEh
) configuration is set. With factory settings, no diagnosis
alarms are transmitted.
Diagnosis alarms result in an interruption of the program run on a Siemens
control unit and in invocation of the OB82 or OB86 functional modules. If
the selected modules are not available on the CPU, the CPU will switch over
to the STOP condition.
The position indicator's PROFINET interface supports diagnosis alarms in case of a device
error. For displaying diagnosis information, the USI, User Structure Identifier 8000h is used
for channel diagnosis. The error codes are converted into the ChannelErrorType according to
the following table.
