Fetching control
The 3RW5 HMI actively fetches master control via the action "LOCAL / REMOTE" from the
lower priority control source.
If master control at the local interface on the 3RW5 HMI High Feature (higher priority), you
must first actively give up master control in SIRIUS Soft Starter ES (TIA Portal). You can
then get master control with the action "LOCAL / REMOTE".

The 3RW5 HMI actively gives up the master control function via the action
"LOCAL / REMOTE" to the "Automatic" mode or alternatively to the Input IN. In the following
cases, master control is given up to the Input IN:
No 3RW5 communication module is installed in the 3RW52 soft starter.

(Page 147) is set to "Permanent activation".
Withdrawal of master control by other control sources
If a command to this effect is issued in SIRIUS Soft Starter ES (TIA Portal) at the local
interface on the 3RW5 HMI High Feature, master control is taken from the 3RW5 HMI.
