the 3RW5
communication
module)
Manual Input controlled
operation local
3RW5 HMI

If the connection to the control source is aborted, the control priority automatically switches
back to the lowest priority of the current mode.
Sets the operating mode
A higher-priority mode can actively take over as master control from a lower-priority mode at
any time; the reverse is not possible.
The master control function can only be returned to the mode with the lowest priority. Control
sources with higher priority must take the master control function from the mode with the
lowest priority.
A mode with lower priority can only take the master control function back while the motor is
switched off.
The mode with higher priority takes over or receives the master control function from the
current mode in the following ways:
● The mode with higher priority actively takes over the master control function:
– 3RW5 HMI: With the action "LOCAL / REMOTE"
– SIRIUS Soft Starter ES (TIA Portal)
● The digital inputs receive the control priority from an operating mode with lower priority
via the following options:
– Via the "Manual operation local - input controlled" bit in the process image output
– SIRIUS Soft Starter ES (TIA Portal) (depending on the 3RW5 communication module)
