Virtual Inputs
Figure 6.9: Virtual Inputs
The relay can control its internal functions and connected devices both
locally and remotely. Thirty general purpose logic points are accessible
via DNP3 and the TUI. The 30 virtual inputs are individually controlled
and include a set, reset and pulse function. The latch state is retained
during setting changes and relay power down conditions. The 30 virtual
inputs conform to DNP3 standards. Use the DNP3 functions such as
SBO (select before operate), Direct Operate, or Direct Operate with no
acknowledge to control virtual inputs.
Use virtual inputs to:
• control circuit breakers
• enable or disable reclosing
• enable or disable under-frequency load shedding
