MicroLogix 1400 Distributed Network Protocol (DNP3) Appendix F
For the MicroLogix 1400 Series A controllers, you can see the following tabs.
If you want to communicate with DNP3 protocol using Channel 0 port, both
Channel 0 and DNP3 Slave configurations should be set. If you want to
communicate with DNP3 protocol using Channel 2 port, Channel 2 and DNP3
Slave configurations should be set.
If you want to communicate with DNP3 protocol using both Channel 0 port and
Channel 2 port, Channel 0, Channel 2 and DNP3 Slave configurations should be
set.
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.
