5.5.2
Module interrupts (COM PROFIBUS)
You can assign parameters to diagnostic and hardware interrupts for modules
having analog inputs with COM PROFIBUS.
For
S modules with analog outputs
S EM 142 DO 4
S PM 148 DO 4
S BM 143-DESINA and EM 143-DESINA
S BM 141 DI 8
S EM 141 DI 8
it is possible to configure diagnostic interrupts.
The alarms are simulated in the extended diagnosis of the ET 200X (see Section
5.6.9). You can continue processing the interrupt messages in the user program of
the DP master.

ET 200X diagnostics with STEP 7 and STEP 5
Slave diagnosis
The slave diagnosis behaves in accordance with the IEC 61784-1:2002 Ed1 CP
3/1 standard. Depending on the DP master, It can be read using STEP 7 or
STEP 5 for all DP slaves that comply with the standard.
Displaying and structuring the slave diagnostics is described in the following
sections.
BM 141, BM 141-ECOFAST, BM 142 and BM 143-DESINA provide the slave
diagnosis that complies with the Standard. Note the differences in the diagnostic
frame depending on which version and which release you have.
The basic modules provide an extended diagnosis, depending on the DP master
and the parameterization.
Note
S
The extended diagnosis can only be used in the slave mode that complies with
the Standard (not in S7 slave operation).
S
Diagnosis as per the Standard and module diagnosis will always be signaled,
even if no alarm is enabled during parameterization of the basic module.
