Technical Manual
3.11.2.2 Functionality
Local/Remote control is by default realized through the R/L button on the front panel. The
control via binary input can 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.
Table 97: Truth table for CONTROL
The station authority check based on the command originator category can be enabled by
setting the value of the Station authority setting to "Station, Remote" (The command
originator validation is performed only if the LR control setting is set to "Binary input").
The station authority check is not in use by default.
