Blockings
M13446-50 v5
The blocking states for position indications and commands are intended to provide
the possibility for the user to make common blockings for the functions configured
within a complete bay.
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.
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 can handle the
control without LogOn. The users and passwords are defined with the IED Users
tool in PCM600.
