Technical reference manual
The blocking facilities provided by the bay control function are the following:
• 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, signal from DO (Data Object) Behavior (IEC 61850–
8–1). If DO Behavior is set to "blocked" 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 in PCM600.
