Module Removal/Insertion Interrupt

The module ID that was removed or inserted is in byte x+4 to x+8. You can find the

IDs for the individual modules in the device master file. You can tell whether the

module was removed or inserted by the type of interrupt in byte x+1 (see

Figure 6-11, on page 6-32).

6.4.10 Evaluating Interrupts from the Station Diagnosis

The structure of the station diagnosis is the same as the structure of the interrupt

section, as described in Section 6.4.9.

Interrupts with S7/M7-DP Master or DPV1 Master

The ET 200M supports the following interrupts:

 Diagnostic interrupt

 Process interrupt

 Module insertion/removal interrupt.

You can evaluate these interrupts with an S7/M7-DP master or DPV1 master. In

the case of an interrupt, interrupt OBs run automatically in the master CPU (see

the System Software for S7-300/S7-400, Program Design Program Manual).
