HP MicroLogix 1761-NET-ENI RSLinx on Ethernet PC Connected to Ethernet, ENI Functional Overview

3-2Operation

ENI Functional Overview		The ENI provides Ethernet/IP connectivity for RS-232 devices that use
		DF1 full-duplex protocol. DF1 full-duplex is an open, point-to-point
		protocol used in any Allen-Bradley controller with an RS-232 port, and
		in many other devices. DF1 full-duplex supports up to 256 nodes. The
		ENI uses these nodes for different functions.
		The ENI uses a memory (node) map to provide access to the different
		functions you can perform. Each function uses a different group of
		node addresses. The following table illustrates the ENI functions by
		groups of node numbers:
ENI Function	Node Group	Node Function	Valid Data Type	For More
				Information
Message Routing	Node 100 to 149	Configure Route Address	Integer	see chapter 5
	Node 0 to 49	Route DF1 MSG to IP at Configured Route	Integer	see chapter 5
		Address
E-Mail	Node 150 to 199	Configure SMTP e-mail address	String	see chapter 6
	Node 50 to 99	Send e-mail message to configured SMTP	String	see chapter 6
		e-mail address
ENI Configuration	Node 248 to 254	ENI Configuration Registers	Integer or String	see chapter 4
			depending on parameter

Program Upload/Download and On-Line Sessions

The ENI allows you to connect from your PC to controllers over Ethernet. The following procedure can be used when the computer has a connection directly onto Ethernet (PCI card, PCMCIA interface, built in TCP/IP port, etc.) and the ENI is plugged into the computer’s RS-232 (COMM) port.

RSLinx on Ethernet (PC Connected to Ethernet)

IMPORTANT

You must use RSLinx version 2.30.00 or newer to connect with the 1761-NET-ENI.

Follow these steps to configure RSLinx for Ethernet operation.

1.Open RSLinx and open the driver configuration dialog.
