Communication Protocols
Please try to avoid gaps that will slow down the performance of the DNP communication. That means do not leave
unused inputs / outputs in between used inputs / outputs (e.g. Do not use Binary Output 1 and 3 when 2 is
unused).
Application Example Setting a Relay:
Binary Output signals of the DNP cannot directly be used in order to switch relays because the DNP Binary Outputs
are pulse signals (by DNP definition, not steady state). Steady states can be created by means of Logic functions.
The Logic Functions can be assigned onto the Relay Inputs.
Please note: You can use a Set/Reset element (Flip Flop) from Logics.
