I am working on a building that is using 4 BCX1 units. I am unable to communicate with two of the units from the workstation. The status of both of the units if offLine while the other two units are still onLine. Looking at the controllers themselves the cpu light its doing strange things. Under the cpu light it says BacNet - green and Infinet-yellow. The light is currently solid yellow and reading the manual there doesnt seem to be any information on this. Under the CPU-Blinking Patterns sections there is only information for a light blinking at 5hz or 2hz with 2hz indicating an error. I am not sure what a solid yellow light would mean in my case. I know that the device needs to be in BacNet mode because the other two functional devices are and have the blinking green light. Does anyone know what the solid yellow light could mean? Thanks
