Analyzing Interrupts From Station Diagnosis - Siemens SIMATIC ET 200X Manual

5.6.10

Analyzing interrupts from station diagnosis

The structure of the station diagnosis is the same as the structure of the interrupt
section, as described in Section 5.6.9.
Interrupts with S7 DP master
The ET 200X supports the following alarms:
S Diagnostic interrupt
S Hardware interrupt
You can evaluate these interrupts with an S7 DP master. In the case of an
interrupt, interrupt OBs run automatically in the CPU (see the System Software for
S7-300/S7-400, Program Design programming manual).
Interrupts with another DP master
If you operate the ET 200X with another DP master, these alarms will be simulated
as device-specific diagnosis of the ET 200X. You must postprocess the relevant
diagnostic events in the DP master's user program.
