Description
1.5 Operating modes and master control function
"Automatic" mode
Receive master control function
The "Automatic" mode receives the master control function from the "Manual - bus" or
"Manual - local" mode as follows:
● Command in SIRIUS Soft Starter ES (TIA Portal) Premium (fieldbus)
● Action "LOCAL / REMOTE" on the 3RW5 HMI
● Command in SIRIUS Soft Starter ES (TIA Portal)
(local interface on the 3RW5 HMI High Feature)
Assume 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
from the Input IN.
Relinquish 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 "Automatic" mode gives up the master control function to
the Input IN.
Revocation of the master control by other control sources
In the "Automatic" mode, the master control function can be withdrawn from any control
source.
Operating mode "manual - bus"
Assume master control
SIRIUS Soft Starter ES (TIA Portal) Premium actively assumes the master control function
from the "Automatic" mode in the event of a corresponding command.
Relinquish master control
SIRIUS Soft Starter ES (TIA Portal) Premium actively passes on the master control function
to the "Automatic" mode in the event of a corresponding command.
Revocation of the master control by other control sources
The master control function is withdrawn from the operating mode "manual - bus" by the
operating mode "manual - local" as follows:
● Activation of 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)
● Action "LOCAL / REMOTE" on the 3RW5 HMI
● Command in SIRIUS Soft Starter ES (TIA Portal)
(local interface on the 3RW5 HMI High Feature)
