Interrupt, error and system messages
9.1 PROFIBUS DP
Slave diagnosis in accordance with standard
The IM 153-x makes available to you the slave diagnosis in accordance with the standard.
Observe the differences in the diagnostic frame in dependence on the version of the IM 153-
x and of the general version.
In dependence on the DP master and the configuration the interface module
IM 153-1 as of 153-1AA03, module version 02, GSD-Version V1.18;
IM 153-1 as of 153-1AA83, module version 01, GSD-Version V1.18;
IM 153-2 as of 153-2AA02, module version > 06, GSD-Version V1.9;
IM 153-2 FO as of 153-2AB01, module version > 05 , GSD-Version V1.5;
IM 153-2 as of 153-2BA00, module version ≥ 01, GSD-Version V1.0;
IM 153-2 FO as of 153-2BB00, module version ≥ 01, GSD-Version V1.0
IM 153-2 as of 153-2BA01, module version ≥ 01, GSD-Version V1.0;
IM 153-2 as of 153-2BA81, module version ≥ 01, GSD-Version V1.0;
provide an enhanced diagnosis. Here, in the diagnostic frame you will find detailed
information in the form of the module status and channel-specific diagnoses (refer to figure
above).
Information on "enhanced diagnosis"
To be able to use the channel-related diagnosis, you must enable the diagnostic interrupts
for each I/O module of the configuration.
When configuring the IM 153-x you can enable or block the diagnostic, process and removal
insertion interrupts and you can do this independently of the enabling of "enhanced
diagnosis".
Via the DPV1 parameter (as of GSD rev. 3) you can block or enable the individual blocks of
the enhanced diagnosis. Blocked diagnoses will be removed from the diagnostic frame.
Important: If you have enabled "enhanced diagnosis" during the configuration and a
diagnostic interrupt is triggered for a module only whilst the ET 200M is running, a channel
error will not be immediately entered in the diagnostic frame. Only after the triggering of the
first diagnostic interrupt of the module, generated after enabling, is a channel error entered in
the diagnostic frame .
In order to delete channel errors from the diagnostic frame you must switch off the
"enhanced diagnosis" in the configuration.
IM 153-2Bx00 and IM 153-2Bxx1
With IM 153-2Bx00 and IM 153-2Bxx1 the enhanced diagnosis is available as default in the
DPV0 / DPV1 mode. It can be deselected (switched off) in blocks during the configuration.
