Operating modes and master control function
Control source and master control
The operating modes assign access rights to the various control sources (access sources). The
control source that possesses the rights for controlling and writing access has control. As only
one control source can ever have control at one time, different priorities are assigned to the
operating modes. Read access is also possible without control.
①
Control source: 3RW5 HMI, operating mode: Manual operation local - HMI controlled
②
Control source: Input IN, operating mode: Manual operation local - input controlled
③
Control source: Modbus client or Modbus master, operating mode: Automatic
④
Control source: PLC, operating mode: Automatic
"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 3RW51 soft starter via the 3RW5
communication module.
In "Automatic" mode, control is with a higher-level control:
• PROFINET, PROFIBUS: Programmable logic controller (PLC)
• Modbus RTU: Modbus Master (e.g. PLC)
Operating mode "manual - local"
In operating mode "manual - local", control is with a control source directly on the 3RW51 soft
starter:
• Input IN
• 3RW5 HMI (accessory)
