Communication Protocols
Point Mapping
Please take into account that the designations of inputs and outputs are set from
the Masters perspective. This way of choosing the designations is due to a
definition in the DNP standard. That means for example that Binary Inputs that can
be set within the Device Parameters of the DNP protocol are the “Binary Inputs” of
the Master.
Call up menu [Device Para/DNP3/Point Map]. Once the general settings of the DNP protocol are done, the point
mapping is to be done as a next step.
•
Binary Inputs (States to be send to the master)
•
Double Bit Inputs (Breaker states to be send to the master)
•
Counters (Counters to be send to the master)
•
Analog Inputs (e.g. measured values to be send to the master). Please take into account that floating
values have to be transmitted as integers. That means they have to be scaled (multiplied) with a scaling
factor in order to bring them into the integer format.
Use Binary outputs in order to control e.g. LEDs or Relays within the protective device (via Logic).
