Supported by 3RW55 soft starter from firmware version V2.1
2)
For 3RW50, 3RW52, 3RW55 soft starters with firmware version earlier than V2.1 and 3RW55 Failsafe, it is not possible
to combine the message bits. For the 3RW55 soft starter as of firmware version V2.1 if the digital inputs have master
control by activating the "Manual operation local - input controlled" bit in the process image output (PIQ). The PLC can
regain master control at any time.
3)
Combining the message bits is possible for 3RW50, 3RW52, 3RW55 and 3RW55 Failsafe Soft Starters. For
3RW55 soft starters as of firmware version V2.1, only if the input action "Operating mode manual - local" has been
parameterized and activated.
For more information on setting the operating mode, see chapter Operating modes and
master control function (Page 32).
