Issue
Using a PE program to try and perform a readproperty on a 3rd party bacnet controller point
Environment
CX 9680
3rd party Bacnet controller
Cause
CX 9680 does not communicate with the Bacnet Protocol unless there is an Xdriver enabled and configured on the CX9680
Resolution
There are 3 solutions to this issue.
- Either purchase an Xdriver for bacnet communications to communicate to the 3rd party IP Bacnet Device
- Install a BCX4040 on the site to handle the Bacnet communications. With this option you'll have much more flexibility to expand and add Bacnet capability in the future.
- Use a workstation program to handle the readproperty from the 3rd party bacnet device. This will work but if the workstation is shut down or the workstation has issues the communications to the 3rd party device will stop working.
