HP MicroLogix 1761-NET-ENI manual ENI #1 Configuration ENI IP Addr Screen

Connecting 1769-L20 CompactLogix Controllers on Ethernet 7-5

For this example, we will be using 38400 baud on all serial connections. We will also assign IP addresses to all Ethernet products rather than using BOOTP.

Two tabs in the ENI software tool must be modified for the purposes of this example, the “ENI IP Addr” tab and the “Message Routing” tab. The IP address for the ENI connected to the 1769-L20 controller (ENI #2) is the only address we need to add to the ENI #1 Message Routing table. The other two Ethernet devices are accessed by the computer via the computer’s Ethernet card. Make the two ENI #1 tabs look like the following:

Figure 7.5 ENI #1 Configuration - Message Routing Screen

Before we download our configuration to ENI #1, we must configure the “Utility Settings” tab in the ENI configuration tool. Make this tab look like the following.
