Chapter

Quick Start

This chapter can help you get started quickly using the PLC-5 Ethernet Interface Module. We base the procedures here on the assumption that you have an understanding of:

• PLC-5 products

• TCP/IP protocol

• Internet addressin g

Because this is a quick start guide for experienced users, this chapter

does not contain detailed explanations about the procedures listed. It does, however, reference other chapters in this book where you can get more information.

If you have any questions or are unfamiliar with the terms used or concepts presented in the procedural steps, always read the

referenced chapters and other recommended documentation before trying to apply the information.

Step 3 Attach the connector header to the processor See Chapter 2

Installing the Interface Module

connector header

Attach the interface module to this end.

Push the exposed pins into the holes on the PLC-5 processor.

Wear a grounding wrist strap to guard against ESD.

Important : Make sure you carefully align the pins and holes before you press the connector header into the processor. If you improperly align them, you will bend the connector header pins when you press them together. Do not use excessive force on the connector header when seating it into the processor. You do not need to key the connector.

Quick Start 1-5

Step 7 Configure channel 3A for Ethernet communication. See Chapter 3

Configuring the Interface Module for Ethernet Communication

A. Be sure channel 3A is designated as the channel supporting the

1785-ENET module.

• Your programming software must support configuration for

channel 3A.

• The PLC-5 processor must contain the proper firmware

revision. See chapter 2.

• If you are configuring online and the interface module is

attached to the processor, channel 3A will automatically support the interface module.

• If you are configuring offline, follow the steps listed in your

programming software documentation.

B. Specify Ethernet-specific configuration information (including

the IP address) using any one of these methods:

• manually configure channel 3A using your programming

software

• use a BOOTP server already on your network (see your

Ethernet network administrator for assistance). Rockwell Automation offers a BOOTP tool on

http://www.ab.com

Important: Assign a diagnostics file to store all status informati on for channel 3A. Use your programming software to select an unused integer file number (10-999). The software creates an integer file that is 44 words long.
