Appendix F MicroLogix 1400 Distributed Network Protocol
If you want to communicate with DNP3 protocol using both Channel 0 port
and Channel 2 port, Channel 0, set Channel 2 and DNP3 Slave configurations.
In this case, the channel which is directed in DNP3 Slave configuration
supports full functionality. But, the other port supports limited functionality
and it does not support some features like Unsolicited Response.
DNP3 Slave configuration is shared by both Channel 0 and Channel 2 ports if
the Channel 0 and Channel 2 are configured to DNP3 protocol. Any changes in
DNP3 Slave configuration tab will affect both channels.
For the MicroLogix 1400 Series B and Series C controllers, you can see the
following tabs.
DNP3 Slave configuration is shared by Channel 0, Channel 1 and Channel 2
ports if Channels 0, 1 and 2 are configured for DNP3 protocol. Any changes in
the DNP3 Slave configuration tab will affect all channels.
