Micro870 Controller Distributed Network
Protocol
Overview This chapter describes how to configure the DNP3 communication settings.
Topics include:
Channel Configuration for
DNP3 Slave
The default communication protocol for the serial ports is DF1 Full-Duplex. To
communicate with Distributed Network Protocol (DNP3), the channel must be
configured for DNP3 Slave.
The default communication protocol for the Ethernet channel in the controller
is EtherNet/IP. To communicate with DNP3 over IP protocol, select DNP3 over
IP Enable in the Ethernet configuration page.
To program the controller, use Connected Components Workbench software
version 20.01.00 or later.
