Replacing an IM 151-7 CPU (6ES7 151-7Ax00-0AB0) with an IM 151-7 CPU
(6ES7 151-7AA10-0AB0) in the configuration
If the user does not make any changes to the configuration, the functional settings
in the configuration are set to default values if an IM 151-7 CPU
(6ES7 151-7Ax00-0AB0) is replaced with an IM 151-7 CPU
(6ES7 151-7AA10-0AB0).
This has the following effect:
The IM 151-7 CPU (6ES7 151-7Ax00-0AB0) was set to No DP (i.e.
stand-alone).
the IM 151-7 CPU (6ES7 151-7AA10-0AB0) is set to ”MPI”.
The IM 151-7 CPU (6ES7 151-7Ax00-0AB0) was set to DP Slave”.
the IM 151-7 CPU (6ES7 151-7AA10-0AB0) is also set to DP Slave”.
Information for replacement in HWConfig
Marking and then replacing the IM 151-7 CPU does not function.
Replacement is only possible after the rack has been selected.
PD/OP functions
In IM 151-7 CPU (6ES7 151-7Ax00-0AB0), PD/OP functions at the DP interface
were only possible at an active interface.
In IM 151-7 CPU (6ES7 151-7AA10-0AB0), these functions are possible at both
passive and active interfaces. However, the performance at the passive interface is
noticeably lower.
In IM 151-7 CPU with a DP master module, the PD/OP functions are also available
via the DP master interface.
Routing in IM 151-7 CPU used as an I slave
If you are using the IM 151-7 CPU (6ES7 151-7AA10-0AB0) as an intelligent slave,
the routing function can only be used when the DP interface is active.
Activate the Commissioning/Test Mode checkbox in the DP interface properties in
STEP 7.
