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.
