S7 Communication; Directly Accessing A Sinamics G120 Converter From A Simatic Panel - Siemens SINAMICS G110M Function Manual

Communication via PROFIBUS and PROFINET

3.3 S7 communication

3.3 S7 communication
S7 communication allows the following:
● The inverter is controlled from a SIMATIC panel, also without control system by directly
accessing the inverter via PROFIBUS or PROFINET.
● Remote maintenance by accessing the inverter with STARTER or Startdrive across
network boundaries.
In the following example, we describe how you can switch the inverter on and off through a
SIMATIC panel, how to specify a setpoint and be shown the actual value on the panel.
You can find a description about accessing inverters across network boundaries in the
application document 25339612.
