In "Automatic" mode, control is 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)

"Automatic operation - Input controlled" mode
The "Automatic operation - Input controlled" mode is available for the 3RW55 soft starter from
firmware version V2.1 and the 3RW55 Failsafe soft starter with firmware version higher that
V1.0.0 if the digital inputs have master control by activating the "Manual operation local - Input
controlled" bit in the process image output (PIQ). The PLC can regain master control at any time.
Operating mode "Manual - bus"
For operating mode "Manual - bus", you require a 3RW5 PROFINET or PROFIBUS communication
module and a PC with SIRIUS Soft Starter ES (TIA Portal) Premium / Professional or a web client.
The control source is connected to the 3RW55 or 3RW55 Failsafe soft starter via the
3RW5 communication module.
In operating mode "Manual - bus", a control source on the fieldbus has master control:
• SIRIUS Soft Starter ES (TIA Portal) Premium / Professional
• Web server
(in combination with 3RW5 PROFINET High Feature communication module from firmware
version V2.0)
Operating mode "Manual - local"
In operating mode "Manual - local", master control is with a control source directly on the 3RW55
or 3RW55 Failsafe soft starter:
