5.5.3 Functionality
The binary signal transfer function BSTGAPC is used for transferring binary signals
between the local and remote end line differential protection relays. The function
includes eight binary signals that are transferred in the protection communication
telegram and can be freely configured and used for any purpose in the line
differential application.
BSTGAPC transfers binary data continuously over the protection communication
channel between the terminals. Each of the eight signals are bidirectional and the
binary data sent locally is available remotely as a received signal.
BSTGAPC includes a minimum pulse time functionality for the received binary
signals. Each received signal has its own minimum pulse time setting parameter.
