Remote Inputs - GE F650 Instruction Manual

7 IEC 61850 PROTOCOL
Remote Inputs which create PLC operands at the receiving relay, are extracted from GSSE messages originating in remote
devices. The relay provides 32 remote inputs, each of which can be selected from a list consisting of 96 selections: DNA-1
through DNA-32 and UserSt-1 through UserSt-64. The function of DNA and UserSt bits is in both cases the same so user
can assign a Remote Input either of them through the Bit Pair 1 (32) field (see figure 1). They can be accessed either from
F650 relay:
Actual Values > Input/Outputs > Remote Inputs > Remote Input 1(32)
or from EnerVista 650 Setup (see Figure 7–1:):
Setpoint > Input/Outputs > Remote Comms > Bit Pair 1(32)
Actual > Inputs/Outputs > Remote Inputs > Remote Input
The Default Value 1(32) setting selects the logic state for this point if the local relay has just completed startup or the remote
device sending the point is declared to be non-communicating. The following choices are available:
• ON value defaults the input to Logic 1.
• OFF value defaults the input to Logic 0.
• Latest OFF freezes the input in case of lost communications. If the latest state is not known, such as after relay power-
up but before the first communication exchange, the input will default to Logic 0. When communication resumes, the
input becomes fully operational.
• Latest ON freezes the input in case of lost communications. If the latest state is not known, such as after relay power-
up but before the first communication exchange, the input will default to Logic 1. When communication resumes, the
input becomes fully operational.
They can ONLY be accessed either from EnerVista 650 Setup (see Figure 7–1:)
