DeviceNet Startup Guide

December 22, 2003

Overview:

This guide offers a short-form startup procedure and additional comments regarding the

CONTREX CX1010 controller connections to a DeviceNet network. The CX1010 manual

covers the setup parameters in chapter 5, under the Main Menu\Device Configure\DeviceNet

Setup. Detailed DeviceNet specifications are detailed in a separate CX-Series DeviceNet Card

manual. This short-form guide contains information from both sources, and simplifies the

procedure for most users who meet the "Assumptions" criteria noted below.

Assumptions:

The user is generally familiar with DeviceNet terminology, and wiring practices.

The user is familiar with the specific Host/Scanner card that will control this network.

The Scanner card is probably mounted in a PLC (vs. PC) host controller.

The user is familiar with writing PLC code to manipulate numbers. In particular there

may be a need to move decimal points around by multiplying, or dividing, by 10's.

The primary communications mode will be "Polling", rather than "Explicit Messaging".

The data list (CX1010 parameters of interest) includes no more than 4 "write", nor more

than 4 "read" parameters.

Setup the CX1010:

Go through the Menu and find Main Menu\Device Configure\DeviceNet Setup.

Enter a MAC ID value between 1 and 63. This will be the Node Address for this

controller on your network. Be sure you do not have 2 devices with the same address.

Enter a baud rate. Choices are 125, 250, or 500 kbaud. All devices on the network must

communicate with the Scanner Card at the same network speed.

Enter the unique product serial number for this network card. It would be found with the

information that came with the card. If you cannot locate it, you may proceed with the

setup anyway, as most host systems probably do not use this information anyway.

Proceed to page 2 of the CX1010 DeviceNet Setup menu. Enter the list of parameters

that will be communicated over the network. The correct Parameter Number may be

found from the lists in the CX1010 manual. Alternately, you could find the parameter
