It is also possible to change upgraded projects to symbolic assignment and must be decided
individually, as follow-up work may be required.
Extensive follow-up work is usually required particularly for free telegram configurations (e.g.
for TB30, TM15 DI/DO, TM31).
Note
If the symbolic assignment is activated later, previously existing telegram settings and BICO
interconnections for all SINAMICS telegrams that are set to Standard/Automatic
(Communication -> Telegram configuration) are replaced at the next compilation. This may
change telegrams and BICO interconnections and delete telegram extensions previously set
up manually.
For this reason, make a backup copy of your project before activating the symbolic assignment.
To retain the settings that have been made, after the selection of "Use symbolic assignment,"
the setting "User-defined" must be selected and the check box cleared for automatic telegram
setting/address adaptation for the respective message before compilation.

Assigning a drive later
You can create an axis in SIMOTION SCOUT and assign it later to a drive. You can thus load
your user program to the controller and (with the exception of the non-existent drives) test it.
Compared to a procedure with temporarily created "virtual axes", "axes without assigned drive"
have the advantage that the configuration data is completely available and do not require a
"virtual axis -> real axis" reconfiguration.
Simulation of axes
The axis simulation can also be used to test the user program.
You can find a script for switching the axis simulation on and off in
SIMOTION Utilities & Applications, which is part of the scope of delivery of SIMOTION SCOUT.

Adaptation
In addition to the symbolic assignment, the automatic adaptation facilitates the configuration
of SINAMICS S110/S120 data as of SIMOTION V4.2. During power-up of the SIMOTION
devices, reference variables as well as drive and encoder data of the SINAMICS S110/S120
are automatically taken over for the configuration data of the SIMOTION technology objects
"TO axis" and "TO externalEncoder". This data no longer has to be entered in SIMOTION.
