Compatibilities between the IM 153-x
A.1 Compatibilities between the versions of IM 153 and IM 153-1
Behavior with inserting / removing interrupt
up to
153-1AA03, module version 01
The ET 200M is set up on active bus modules. The
removal/insertion interrupt is disabled at parame-
ter assignment.
The removal or insertion of a module results in
station failure.
Startup Characteristics When Response Monitoring is Switched Off
The IM 153-1 as of 6ES7153-1AA02-0XB0, module version 05 has a different behavior when
the DP normal master is restarted with a switched off response monitoring:
If the response monitoring is switched off, in the event of a DP master failure the outputs of
the ET 200M maintain their set values.
When the DP master starts again without resetting the DP slave these output values remain
until the new output data is received from the DP master.
Without resetting the DP slave means that the DP slave is not enabled for other DP masters. In
the parameter assignment message frame, the bit 6 of the "Octet 1: station_status,
unlock_req" has the value "0" (e.g. with the DP master of the SIMATIC 505).
In the case of previous versions: When restarting the DP master, the outputs of the ET
200M are briefly set to "0" until they are reset by the DP master.
If the response monitoring switched on is set, the IM 153-1AA02 as of E05 behaves like the
predecessor versions.
Configuration of the IM 153-1 with the general ID format (AKF)
You can also configure the IM 153-1 as of order number 6ES7153-1AA03-0XB0, module
version 02, with the general ID format AKF. This configuration assumes detailed knowledge
of the structure of the AKF. You must use the code 0x00 for the slots 1 to 3.
If you conduct the configuration with the general ID format AKF, the quality of the
comparison of the preset and actual configuration when the DP slave starts up or when
removing or inserting modules is very low. Since there is no type ID available for the
comparison, an incorrect configuration cannot be easily detected!

WARNING
as of
153-1AA03, module version 02
The ET 200M is set up on active bus modules. The
removal/insertion interrupt is disabled at parame-
ter assignment.
It is still, however, possible to remove and insert
modules. An interrupt is not reported, but the
events are displayed in the diagnosis.
