Cognex In-Sight I/O Expansion Module Installation and operating manual

I/O Expansion Module
Installation & Reference
Overview
The In-Sight™vision sensor supports up to
ten discrete inputs and ten discrete outputs.
Two inputs and two outputs are built-in to
the In-Sight processor. The remaining eight
inputs and outputs require the optional I/O
Expansion Module.

The I/O Expansion Module kit (Cognex
P/N CIO-2350-00) includes the following
components:
• I/O Expansion Module
(P/N 800-5712-2)
• 2.1 m (7.0 ft) I/O Expansion Module
Cable (P/N 300-0274-7)
NOTE: The In-Sight processor supplies power
to the I/O Expansion Module; no external power
supply is necessary.

Installation
This section describes how to connect the I/O Expansion Module to the In-Sight processor and
how to connect input and output lines to the I/O Expansion Module.
Step 1 – Connect the Cables
1. Remove power from the In-Sight processor.
2. Plug one end of the provided cable into the I/O Expansion Module’s 26-pin
connector, and the other into the 26-pin connector on the In-Sight processor
labeled EXTERNAL I/O.
CAUTION! The I/O Expansion Module must have the same ground potential as the In-Sight
processor’s chassis. Any difference in potential can damage the equipment. If you connect
a ground wire to the I/O module’s ground screw, then that ground must have the same
potential as that of the In-Sight processor.
3. On the I/O Expansion Module, connect input lines to the input terminals and
output lines to the output terminals. For both input and output signals, connect the
“source” side of the signal to a positive number terminal and the “sink” side to a
negative-numbered terminal. Tighten the set screws.

Step 2 – Configure the Input Lines in the User Interface
1. Power up the In-Sight processor.
2. Using the control pad, highlight any empty cell in the spreadsheet and press
the A3 button to open the System menu.
3. Highlight Settings and press the A1 button to open the Settings menu.
4. To configure a discrete input line, highlight Discrete Input and press A1 to
open the Discrete Input dialog. Configure the selected input lines as needed
and press OK to close the Discrete Input dialog.
You read a discrete input values in the spreadsheet using the Read Discrete function.

Step 3 – Configure the Output Lines
1. Open the Settings menu as in Step 5, but this time highlight Discrete Output
to open the Discrete Output dialog.
2. Configure the selected output line as needed and press OK to close the
Discrete Output dialog.
You write values from the worksheet to the discrete output through the WriteDiscrete
function.
NOTE: In-Sight retains the settings in the Discrete Input and Discrete Output dialogs until you
change them. These settings are system-wide, and apply to all saved jobs.
