MicroLogix 1400 Distributed Network
Protocol (DNP3)
This appendix:
• describes the MicroLogix 1400 Distributed Network Protocol (DNP3).
• describes the procedures used to program and troubleshoot DNP3
protocol in the controller.
• gives an overview of the DNP3 implementation in the controller
• shows application examples of DNP3 applications.
Channel Configuration for
DNP3 Slave
The default communication protocol for the serial ports Channel 0 and Channel
2 in the MicroLogix 1400 is DF1 Full-Duplex. To communicate with DNP3
protocol, the channel must be configured to DNP3 protocol.
The default communication protocol for the Ethernet Channel 1 in the
MicroLogix 1400 is Ethernet/IP. To communicate with DNP3 over IP protocol
in the MicroLogix 1400 Series B controller, the channel must be configured to
use the DNP3 protocol.
The MicroLogix 1400 Series A controller supports DNP3 protocol via Channel
0 and/or Channel 2 Serial ports.
The MicroLogix 1400 Series B controller also supports DNP3 over IP protocol
via Channel 1 Ethernet port.
To program the MicroLogix 1400 controller, use RSLogix 500/RSLogix Micro
software, version 8.10.00 or later for Series A controller and version 8.30.00 or
later for Series B controller.
