3.5

S7 communication

Communication via the S7 protocol facilitates the following:
● Access to the inverter with Startdrive.
● Remote maintenance of the inverter with Startdrive across network boundaries.

● Control of the inverter directly via SIMATIC Panels via PROFIBUS or PROFINET without
higher-level control.
Note
Number of S7 protocol connections
The inverter supports four S7 protocol connections. Two of these are required for Startdrive.
Each of the remaining two are available for access to the inverter via SIMATIC Panels.
