615 series DNP3 Communication Protocol Manual

The DNP3 parameters can be accessed with PCM600 or via the LHMI path Configuration > Communication > DNP3.0n.

Note: Some parameters are not visible in the “Basic” setting visibility mode. To view all parameters use “Advanced” setting visibility mode in Parameter Setting tool in PCM600 and LHMI.
Note: Power must be cycled to the unit after making changes to the DNP3 parameters. The LHMI or WHMI do not notify that this action must be taken.
