SINAMICS G180 converters have a variety of different interfaces via which they can communicate with the Inverter Management Software or other peripheral partners (PCs, PLCs, various communication/control devices, etc.)

Apart from the standard USB interface (connection with one partner), an RS232/485 interface is also provided as standard, which permits simultaneous communication and control with several nodes. These interfaces can also be accessed by means of a modem, USB converter or Ethernet converter and therefore provide a basis for setting up a multi-Ethernet connection, for example, between up to 10 converters.

The SINAMICS G180 has also been equipped with a USB interface which can be connected directly to a PC or laptop. As an option, the SINAMICS G180 can also be supplied with a PROFIBUS interface. With this option installed, the IMS is capable of implementing "master class 1" as well as "master class 2" operation.
