Only one Local/Remote access scenario is possible: "L,R, L+R".
Control access can be simultaneously permitted from local or remote location. Simultaneous local or remote control operation is not allowed as only one client and location at a time can access controllable objects, and they remain reserved until the previously started control operation is first completed by the client. Control access with IEC 61850 originator category station is interpreted as remote access.
The present control status can be monitored in the HMI or PCM600 via with the LR state parameter or from the IEC 61850 data object CTRL.LLN0. LocKeyHMI.
IEC 61850 command originator category is always set by the IEC 61850 client.
