Network compatibility mode

Table 5.10
Pr MM.41
A backwards compatibility mode has been added in SM-PROFIBUS DP-V1 firmware
V03.01.00 and later. Pr MM.41 can be used to allow the SM-PROFIBUS DP-V1 module
to appear as either a UMV 4301 / DMV 2322/2342 or a Digidrive SE, this only applies to
the network and not the control/status words and parameter sizes. The module must be
configured to match the existing network settings of the drive it is replacing (including
any parameter mappings).

Using the compatibility mode allows the replacement of drives on a PROFIBUS-DP
network, without having to make any changes to the master network configuration, it
changes the identity code of the module so that the master believes that a different drive
is present for a particular node.
When using the compatibility mode, the correct GSD file for the simulated drive must be
used and not the SM-Profibus DP-V1 GSD file.
When network compatibility mode (Pr MM.41) is set to a non-zero value, DP-V1
NOTE
functionality is disabled.
Depending on the application, an SM-Applications module may be needed on the drive
NOTE
to account for any changes between the functionality of the two drives (i.e. any changes
between the control and status words).
This mode only changes the network to emulate the Digidrive SE or UMV 4301/DMV
2322/2342 on the network. Changes to the control method and data size differences
must still be considered. This mode does NOT allow direct replacement.
