Installing and Configuring Your ControlNet PLC-5 Backup System 3-25

For the point-to-point DH+ network between the processors, set the

DH+ address based upon the ControlNet node address being an even

or odd number, as shown in the following table:

Reasons for invalid crossload channel configuration:

• Channel 1A must be configured as DH+

• Channel 1A baud rate must be 230.4Kbaud

• Odd-numbered ControlNet PLC-5 DH+ address must be 1

• Even-numbered ControlNet PLC-5 DH+ address must be 2

Correct this by changing the DIP switch to their proper positions

as shown in the above table.

Make the setting in RSLogix 5:

1. In the ControlNet Hot Backup Screen, choose the Crossload tab.

2. In the Crossload Channel dialog, toggle from Channel 2 to

Channel 1A.

If the PLC-5 is not in the invalid backup state, the feature is properly

configured.
