7-2Connecting 1769-L20 CompactLogix Controllers on Ethernet

Purpose

Scope

The computer must include the following software:

•RSLOGIX5000, version 7.00 or later

•RSLINX, version 2.30.00 or later

•RSLOGIX500

•ENI Configuration Tool

The 1769-L20 controller must contain firmware 7.17 or later.

The Ethernet Interface Card in the computer is used to connect directly to the SLC 5/05 controller (channel 1) and to the 5550 controller via the 1756-ENET card. The computer COMM Port is used to connect to the 1769-L20 controller via the 1761-NET-ENI modules and an Ethernet hub/switch.

Provide Ethernet connectivity for 1769-L20 CompactLogix controllers via the RS-232 serial port and the 1761-NET-ENI module.

Connecting 1769-L20 controllers on Ethernet requires one

1761-NET-ENI per L20 controller. The ENI converts RS-232 hardware connections and DF1 full-duplex protocol to Ethernet, TCP/IP.

The ENI must be configured with IP addresses assigned to node numbers 0 to 49. The Destination Node Address in DF1 messages is then used by the ENI to route the message to the proper device on Ethernet.

This application example will show how to configure the ENI module and how to send messages from the 1769-L20 controller to the other Controllers on Ethernet. This example will also show how to initiate messages from the Ethernet controllers to the L20 controller. Messages sent to the ENI module’s IP address will be delivered to the serial port of the L20 controller.

	TIP	In the ENI, node addresses 45 through 49 are
	TIP	dedicated for 1756-ENET/ControlLogix controllers.


		Node addresses 0 through 44 are to be used for all
		other Ethernet devices, such as other 1769-L20
		controllers connected to ENI modules and SLC 5/05
		controllers.
