Appendix F MicroLogix 1400 Distributed Network Protocol (DNP3)

Master Node0

This value is used to:

• validate the Master node address when the Enable Master Address

Validation is Enabled (Checked)

• send Unsolicited Response when Unsolicited Response functionality is

enabled. An Unsolicited Response is sent out to the DNP3 Master having
this address.

The valid range is 0 to 65519. Default value is 0.

Master Node1, Master Node2, Master Node3, Master Node4

The valid range is 0 to 65519. Default value is 0.

This value is used to check validation for Master node address when Enable
Master Address Validation is Enabled (Checked).

Control

For Channel 0, the selections can be No Handshaking, Half Duplex
Modem(CTS/RTS handshaking) and No Handshaking (485 Network).
Default selection is No Handshaking.

For Channel 2, the selections can be No Handshaking, and Half Duplex
Modem(CTS/RTS handshaking).
Default selection is No Handshaking.

When the MicroLogix 1400 is connected to DNP3 Master using RS-232 line
directly, you must select No Handshaking. If you want to use the Modem line in a
half duplex network, you must select Half Duplex Modem(CTS/RTS
handshaking). If the MicroLogix 1400 is connected to an RS-485 network and a
1763-NC01 cable is used, you must select No Handshaking (485 Network).

If you want to send an ASCII string via a serial channel which is configured to
DNP3 Slave protocol, use AWA and AWT instructions to control the Modem.

For Cabling and Connections, see Communication Connections on page 59.

For AWA and AWT instructions, refer to the MicroLogix 1400 Programmable
Controllers Instruction Set Reference Manual,
