•
Blocking of position indications, BL_UPD. This input will block all inputs
related to apparatus positions for all configured functions within the bay.
•
Blocking of commands, BL_CMD. This input will block all commands for all
configured functions within the bay.
•
Blocking of function, BLOCK. If the BLOCK signal is set, it means that the
function is active, but no outputs are generated, no reporting, control commands
are rejected and functional and configuration data is visible.
The switching of the Local/Remote switch requires at least system operator level. The
password will be requested at an attempt to operate if authority levels have been
defined in the IED. Otherwise the default authority level, SuperUser, can handle the
control without LogOn. The users and passwords are defined with the IED Users tool
in PCM600.
