Fetching master control from "Automatic operation - Input controlled" mode
The "Automatic operation - Input controlled" mode is possible for the following 3RW5 soft
starters:

• 3RW55 Failsafe soft starter with firmware version higher than V1.0.0
• Command in the web server
Web page "Control Panel" > "Master Control > Get Control"
Note
Fetching master control from "Automatic operation - Input controlled" mode
The "Automatic operation - Input controlled" mode is possible for the following 3RW5 soft
starters:
• 3RW55 soft starter from firmware version V2.1
• 3RW55 Failsafe soft starter with firmware version higher than V1.0.0
• Action "LOCAL/REMOTE" on the 3RW5 HMI High Feature
• Command in SIRIUS Soft Starter ES (TIA Portal) (local interface on the 3RW5 HMI High
Feature)
Brief overview: Window "Task Card" > Tab "Online Tools" > "SIRIUS Control Panel > Master
Control > Get Control"
Operating mode "Manual operation local - HMI controlled"
Fetching control
The 3RW5 HMI High Feature actively fetches control with the action "LOCAL/REMOTE" from the
lower priority control source.
If control is with the local interface on the 3RW5 HMI High Feature (higher priority), you must
actively give back control beforehand in SIRIUS Soft Starter ES (TIA Portal). You can then fetch
control with the action "LOCAL/REMOTE".
Giving back control
The 3RW5 HMI High Feature actively gives back control with the action "LOCAL/REMOTE" either
to "Automatic" mode or to the digital inputs. If no 3RW5 communication module is installed in
the 3RW55 or 3RW55 Failsafe soft starter, control is given back to the digital inputs.
Withdrawal of control by other control sources
Control is fetched from the 3RW5 HMI High Feature in response to a command to this effect in
SIRIUS Soft Starter ES (TIA Portal) at the local interface on the 3RW5 HMI High Feature.
