Step 7: Setting the I/O Byte Swapping Option

If it is desirable to have the BridgeWay byte swap each 16-bit word in the I/O

table, the Byte Swap option must be enabled. (see the explanation of this option in

“DeviceNet I/O Configuration” on page 3-17.)

• Highlight the BridgeWay module by left clicking on its icon.

• Select the Device menu option and pull down menu.

• Select the Class Instance Editor option. A pop up Message box appears.

Click on Yes. Another screen appears.

• There are several parts to this screen. Make sure the check box titled Val -

ues in Decimal is NOT checked. At the top right is an Object Address

with 3 text boxes. Set the values in these boxes as follows:

- Class set to 3.

- Instance set to 1.

- Attribute set to 65h.

• To the left of the Object Class section is one titled Service Code. There’s

a text box with a pull down selection titled Description. Pull down the

selections and select “Set Single Attribute”.

• The box titled Data Sent to the Device is now available. At the far left of

this box enter a “01” to enable byte swapping, or a “00” to disable it. Then

click on the Execute button.

• A message should appear in the Data received from device box saying the

execution was completed.

Note: Changes to the byte swapping option do not take effect until the module has

been power cycled.
