Overview
The Cognex In-Sight
®
5000 series and In-Sight 3400 vision sensors can communicate with a PLC using
discrete I/O, DeviceNet, or both. This document describes how to configure communications between the
In-Sight sensor and a PLC using the optional DeviceNet Interface Module (referred to as “the Interface
Module”), and includes the following topics:
Connecting the Interface Module to a DeviceNet Network ................................p. 2
Communicating With In-Sight via DeviceNet .....................................................p. 6
The DeviceNet interface module is a serial-to-DeviceNet gateway. The In-Sight sensor communicates to
the Interface Module through a serial port, the Interface Module buffers the serial data and sends it
through DeviceNet to (or from) a DeviceNet scanner attached to a PLC.
To set up this connection, configure two communications channels: one from the In-Sight sensor to the
DeviceNet Interface Module, and the other from the DeviceNet Scanner/PLC to the Interface Module.
Preparing for Installation
The DeviceNet Interface Module kit (Cognex P/N CIO-2550-00) includes the following components:
•
DeviceNet Interface Module (P/N 147-0001)
•
DeviceNet Interface Module diskette (P/N 206-6193), containing a copy of the EDS file for use
with the DeviceNet Interface Module and an In-Sight icon.
To complete the installation, you will also need the following:
•
A configured DeviceNet network that includes a scanner attached to a PLC.
•
An In-Sight 5000 series vision sensor.
•
An RS232 serial cable that supports RTS/CTS hardware handshaking.
Finally, you will need the software installed on a PC to configure and run the PLC. To illustrate the
instructions in this manual, the following was used:
