Sets The Operating Mode - Siemens SIRIUS 3RW55 Equipment Manual

3.6.2

Sets the operating mode

Basic behavior when the operating mode is changed
A higher-priority mode can fetch control from a lower-priority mode at any time; the reverse is
not possible. Control can only be given back to the mode with the lowest priority. Control sources
with higher priority must fetch control from the mode with the lowest priority.
Requirements
• A mode with lower priority can only take control back while the motor is switched off.
• For the "Automatic" mode and operating mode "Manual - bus", you require a
3RW5 communication module.
"Automatic" mode
Note that the 3RW55 and 3RW55 Failsafe soft starters switch to "Automatic" mode after the
3RW5 communication module has been installed in the 3RW55 or 3RW55 Failsafe soft starter.
Receiving control
"Automatic" mode receives control from the operating mode "Manual - bus" or "Manual - local"
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 > Release Control"
• Command in the web server
Web page "Control Panel" > "Master Control > Release Control"
• If the input action "Operating mode manual - local" is parameterized: By deactivating the
input action "Operating mode manual - local".
• 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) or in the data
table "Process image output (PIQ)" (depending on the 3RW5 communication module),
"Automatic" mode receives master control from the digital inputs.
• 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 > Release Control"
Withdrawal of control by other control sources
In "Automatic" mode, master control can be withdrawn by any control source.
