processing. The properties of the DO variables can only be read in the manipulation tasks and
step scripts.
Figure 4-119 Assigning DO variables to SINAMICS components
Note
We recommend that the drive data is assigned to the drive objects via the assignment of DO
variables. Although a direct assignment via a path specification is possible in short form, this
limits the flexibility and can easily result in errors.
Assignment options
There are two ways of assigning the DO variables to the SINAMICS components:
1. When processing the package, you need to manually assign the DO variables to the
SINAMICS components on the "SINAMICS topology" dialog page.
2. The DO variables are assigned to the SINAMICS components as a property during the
configuration of a comparison topology or user-specified topology.
The two topologies are linked into the project on the "SINAMICS topology" dialog page.
Which topology is used during the runtime depends on the configuration of the DRV area
on the "System configuration" dialog page.
