3RW5 communication module.
In the "Automatic" mode the master control function rests with a higher-level control:
● PROFINET, PROFIBUS, EtherNet/IP: Programmable logic controller (PLC)
● Modbus TCP: Modbus Client (e.g. PLC)
● Modbus RTU: Modbus Master (e.g. PLC)

In the operating mode "manual - bus" the master control function rests with the
SIRIUS Soft Starter ES (TIA Portal) Premium software.
