Read Input Register (Function Code 04)
No input registers supported. Response from IED indicates “ILLEGAL FUNCTION.”
Force Single Coil (Function Code 05)
Only the “hold readings” coil can be forced. When active, this coil locks all coil, input and holding register readings simul-
taneously at their present values. When inactive, coil, input and holding register values will read their most recently avail-
able state.
