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.
