3.13.3.2 Functionality
Local/Remote control is by default realized through the R/L button on the front panel. The
control via binary input can be enabled by setting the value of the
LR control setting to
"Binary input".
The actual Local/Remote control state is evaluated by the priority scheme on the function
block inputs. If more than one input is active, the input with the highest priority is selected.
The actual state is reflected on the CONTROL function outputs. Only one output is active
at a time.
