SINAMICS G120/G120D (CU2x0x): How is a routing established from one PG via a PROFIBUS interface through a SIMATIC station to G120/G120D frequency inverter via a PROFINET interface?

  • Entry

Routing involves a transition from one sub-network to one or several other sub-networks located in a SIMATIC station, which has interfaces to the sub-networks involved.
Routing allows an S7 station to be accessed online using a PG/PC across sub-network limits and boundaries. For instance, to download user programs or a hardware configuration or to test and run diagnostic functions.
You can connect a PG at any location in the network and to all stations, which can be reached via network transitions, to establish an online connection.
An example is discussed in this particular FAQ where an online connection is established from one PG via an S7 SIMATIC 300 station equipped with CPU 317F-2 PN/DP to an SINAMICS G120 frequency inverter that is equipped with Control Unit CU240S PN via PROFINET. This means that a transition (routing) is established from the PROFIBUS interface to the Industrial Ethernet interface (refer to Fig. 1).
