Determine Consumed I/O Assembly

Devices, when enabled with DeviceLogix functionality, can receive

additional data across DeviceNet. This data is called network inputs.

The consumed I/O parameter lets you select how much data you

want the device to consume from a master. After setting this

parameter, the same number of bytes must be selected in the

scanner’s scan list. For example, if you choose 3 bytes of data to be

consumed, you must indicate that 3 bytes of data are to be transmitted

in the scanner’s scanlist. If the number of consumed bytes and the

number of transmitted bytes do not match, the connection cannot be

made.

Note that this parameter is not in all DeviceLogix-enabled devices.

To change a consumed I/O assembly:

1. Click the current value of the Consumed I/O Assembly.

The field turns into a drop-down list box.

2. Click the arrow to display the values.

3. Click the desired value.

4. Click Apply to save the new value without closing the window.

Or, click OK to save the new value and to close the window.
