Description
3.5 Operating modes and master control function
"Manual operation local - input controlled" and "Automatic - input controlled" modes
Fetching master control
The input IN or the digital inputs receive master control from the "Automatic" mode or
"Manual - bus" mode as follows:
● 3RW50, 3RW52 soft starters and for 3RW55 and 3RW55 Failsafe soft starters if the input
action "Operating mode manual - local" is not parameterized: By activating the
"Manual operation local - input controlled" bit in the process image output (PIQ)
(Page 119).
● For 3RW55 and 3RW55 Failsafe soft starters if the input action
"Operating mode manual - local" is parameterized: By activating the input action
"Operating mode manual - local".
If the master control function is on the 3RW5 HMI or, in the case of the local interface, on the
3RW5 HMI High Feature (higher priority), you must actively give up the master control
function beforehand. The input IN or the digital inputs can then fetch master control.
Relinquishing master control
"Automatic" mode receives control as follows:
● 3RW50, 3RW52 soft starters and for 3RW55 and 3RW55 Failsafe soft starters if the input
action "Operating mode manual - local" is not parameterized: By deactivating the
"Manual operation local - input controlled" bit in the process image output (PIQ)
(Page 119).
● For 3RW55 and 3RW55 Failsafe soft starters if the input action
"Operating mode manual - local" is parameterized: By deactivating the input action
"Operating mode manual - local".
Withdrawal of master control by other control sources
Master control is withdrawn from the input IN or digital inputs as follows:
● Command in SIRIUS Soft Starter ES (TIA Portal) Premium / Professional (fieldbus)
Brief overview: Window "Task Card" > Tab "Online Tools" > "SIRIUS Control Panel >
Master Control > Get Control"
Note
Fetching master control from "Automatic - input controlled" mode
The "Automatic - input controlled" mode is possible for the following 3RW5 soft starters:
• 3RW55 soft starter from firmware version V2.1
This operating mode is not possible for the 3RW55 Failsafe soft starters with firmware
version V1.0.
● "LOCAL / REMOTE" action on the 3RW5 HMI
● 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"
