Blockings
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.
• 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.

Local remote/Local remote control LOCREM/LOCREMCTRL

The function block Local remote (LOCREM) handles the signals coming from the
local/remote switch. The connections are seen in figure 128, where the inputs on
function block LOCREM are connected to binary inputs if an external switch is used.
When the local HMI is used, the inputs are not used and are set to FALSE in the
configuration. The outputs from the LOCREM function block control the output
PSTO (Permitted Source To Operate) on Bay control (QCBAY).
