AUMA AC 01.2 User Manual

Enable/disable local controls via fieldbus commands
For control via fieldbus interface, the command for enabling the local controls is done
via fieldbus command Fieldb. enable LOCAL.
Switching behaviour:
●
Fieldb. enable LOCAL = 1 = enable:
Operation via local controls enabled
●
Fieldb. enable LOCAL = 0 = disabled:
Operation via local controls disabled
Information
In the event of loss of fieldbus communication, the local controls will be disabled
since no enable signal is present.
If operation commands are not transmitted via fieldbus commands, but via <Additional
inputs> or an additional <Parallel interface>, a digital input has to be available and
configured to enable/disable the local controls.
Configuration of digital input
Required user level: Specialist (4).
