7.1.4 Remote inputs
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
to DNA-32 and UserSt-1 to 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 to 32 field (see figure 1). They can be configured using the EnerVista 650
Setup program in the menu Setpoint > Input/Outputs > Remote Comms.
