32 PLC-5 Ethernet Interface Module

Publication 1785-IN019B-EN-P - January 2007

With the latest release of the Ethernet PLC-5 controllers and RSLogix programming

software, version 5.20 or later, you can enter the symbolic form of the IP address as the IP

address in the Message Block.

The Channel Configuration feature in RSLogix5 programming software lets you configure a

primary and secondary DNS server, as well as a default domain name (for example,

cle.ab.com).

DNS names consist of a label name and a domain name. When programming the message

instruction, you can enter the full label and domain name (for example, Motor1.cle.ab.com) or

just the label name (Motor1). The default domain name (cle.ab.com) is appended to the label

name.

Label names must start with a letter and can only consist of letters, digits, and hyphens.

When a message instruction with a label name is first used, the PLC-5 controller verifies that

label name with the name servers. When the IP address is returned, the connection is made.

After the connection is made, subsequent message instructions will not require label name

verification.

Embedded Web Server

Follow these directions to use the embedded Web server:

1. Go online at your controller’s IP address (for example, www.cle.ab.com).

The 1785-ENET Ethernet Module main page appears.

2. Select the first item, Module Information.

The Module Information page appears and displays specific controller information.

3. Select TCP/IP Configuration at the bottom of the Module Information dialog.

The TCP/IP Configuration page appears and displays TCP/IP parameters.

4. Select Diagnostic Information at the bottom of the TCP/IP configuration dialog.

The Diagnostic Information page appears and displays two lists of statistics pages.

The first list contains Network Stack Statistics. These pages present information

about the TCP/IP stack.

For example, from the Network Stack Statistics list, select the first entry, General

Ethernet Counters.
