3.17.11.2 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 binary input control requires that the
CONTROL function is instantiated in the product configuration.
Local/Remote control supports multilevel access for control operations in
substations according to the IEC 61850 standard. Multilevel control access with
separate station control access level is not supported by other protocols than IEC
61850.
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 priority order is "off", "local", "station", "remote", "all".
The actual state is reflected on the CONTROL function outputs. Only one output is
active at a time.
