Teleprotection inputs/outputs and direct inputs/outputs are mutually exclusive – as such, they cannot be used
simultaneously. Once teleprotection inputs and outputs are enabled, direct inputs and outputs are blocked, and vice
versa.

LOCAL RELAY ID NUMBER, TERMINAL 1 RELAY ID NUMBER, and TERMINAL 2 RELAY ID NUMBER: In installa-
tions that use multiplexers or modems, it is desirable to ensure that the data used by the relays protecting a given line
is from the correct relays. The teleprotection function performs this check by reading the message ID sent by transmit-
ting relays and comparing it to the programmed ID in the receiving relay. This check is also used to block inputs if inad-
vertently set to loopback mode or data is being received from a wrong relay by checking the ID on a received channel.
If an incorrect ID is found on a channel during normal operation, the
FlexLogic operand is set, driving the event with the same name and blocking the teleprotection inputs. For commis-
sioning purposes, the result of channel identification is also shown in the
