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.
