1.5 Operating modes and master control function
"Automatic" mode
For the "Automatic" mode you require a 3RW5 communication module and a higher-level
control (e.g. PLC). The control source is connected to the 3RW50 soft starter via the
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)
Operating mode "manual - bus"
For the "Manual-bus" mode you require a 3RW5 PROFINET or PROFIBUS communication
module and a PC with SIRIUS Soft Starter ES (TIA Portal) Premium. The control source is
connected to the 3RW50 soft starter via the 3RW5 communication module.
In the operating mode "manual - bus" the master control function rests with the
SIRIUS Soft Starter ES (TIA Portal) Premium software.
Operating mode "manual - local"
In the operating mode "manual - local" the master control function rests with a control source
directly on the 3RW50 soft starter:
