Siemens SIRIUS 3RW55 - 2 Safety Information; 2.1 ESD Guidelines

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)
Note
"Automatic operation - Input controlled" mode
The "Automatic operation - Input controlled" mode is available for the 3RW55 soft starter from
󹪝rmware version V2.1 and the 3RW55 Failsafe soft starter with 󹪝rmware 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 󹪝eldbus has master control:
• SIRIUS Soft Starter ES (TIA Portal) Premium / Professional
• Web server
(in combination with 3RW5 PROFINET High Feature communication module from 󹪝rmware
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:
• Digital inputs
• 3RW5 HMI High Feature
• SIRIUS Soft Starter ES (TIA Portal) via local interface on the 3RW5 HMI High Feature
