dnp3 simulator software used to demonstrate multi drop architecture of protocol.
A multi-drop connection is similar to a RS-485 configuration, where the master sends the same data along the same line to all its outstations, each with its own unique address, but only the outstation addressed by the master needs to reply.
In this we connected 3 outstations to one master.
master get all outstation data ( BI, BO, AI, AO) and send commands (BO, AO)to outstations.
