"Manual operation local - input controlled" mode
Assume master control
By enabling the "Manual operation local - input controlled" bit in the process image output
(PIQ) or in the data table "Process image output (PIQ)" (depending on the
3RW5 communication module), the Input IN receives the master control function from the
"Automatic" mode or operating mode "manual - bus".
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. Subsequently the Input IN can assume the master control function.
Relinquish master control
By disabling the "Manual operation local - input controlled" bit in the process image output
(PIQ) or in the data table "Process image output (PIQ)" (depending on the
3RW5 communication module), the "Automatic" mode receives the master control function.
Revocation of the master control by other control sources
The master control function is withdrawn from the Input IN as follows:
● Action "LOCAL / REMOTE" on the 3RW5 HMI
● Command in SIRIUS Soft Starter ES (TIA Portal)
(local interface on the 3RW5 HMI High Feature)
"Manual operation local - HMI controlled" mode
Assume master control
The 3RW5 HMI actively assumes the master control function via the action "LOCAL /
REMOTE" from the lower priority control source.
If the master control function at the local interface on the 3RW5 HMI High Feature (higher
priority), you must actively give up the master control function beforehand in
SIRIUS Soft Starter ES (TIA Portal). You can then assume the master control function by
means of the action "LOCAL / REMOTE".
Relinquish master control
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 the
master control function is given up to the Input IN.
● No 3RW5 communication module is connected to the 3RW50 soft starter.
● The parameter "Control via digital input" (Page 139) is set to "Permanent activation".
Revocation of the master control by other control sources
In the event of a corresponding command in SIRIUS Soft Starter ES (TIA Portal) at the local
interface on the 3RW5 HMI High Feature, the master control function is taken from the
3RW5 HMI.
