7.5 Additional information on configuring the SINAMICS Integrated
At the CX32‑2 end, it is possible to access the CU‑Link via the parameters on the DO
CU_CX32. At the SINAMICS Integrated end, the parameters are accessed via the DO
CU_LINK.
Note
There are only CU‑Link communication channels between the SINAMICS Integrated and the
CX32‑2 Controller Extensions. Such a communication channel does not exist between the
individual Controller Extensions CX32‑2. If data are to be exchanged between Controller
Extensions CX32‑2, this is only indirectly possible via the SINAMICS Integrated.
