The figure shows the signal flow among the three IEDs.
In three-terminal applications, both the remote terminals must grant permission to trip. Therefore, at each terminal, direct
inputs 5 and 6 are ANDed in FlexLogic and the resulting operand configured as the permission to trip (
setting).

5.9.7 Teleprotection inputs and outputs

5.9.7.1 Overview
The relay provides 16 teleprotection inputs on communications channel 1 (numbered 1-1 through 1-16) and 16
teleprotection inputs on communications channel 2 (on two-terminals two-channel and three-terminal systems only,
numbered 2-1 through 2-16). The remote relay connected to channels 1 and 2 of the local relay is programmed by
assigning FlexLogic operands to be sent via the selected communications channel. This allows the user to create
distributed protection and control schemes via dedicated communications channels. Some examples are directional
comparison pilot schemes and direct transfer tripping. Note that failures of communications channels affect
teleprotection functionality. The teleprotection function must be enabled to utilize the inputs.
