Tim,
I’ve learned a lot more about this system since yesterday. There are actually 5 serial devices connected to this module. 4 are powered down and labeled “out of service”, they also are generating the comm fault, but I ignored these yesterday as those alarms were already active before I touched anything. Once I got connected to the anybus module and saw the folder structure I understood that subnet is the serial side of this device. I cycled power on the serial device and it started communicating. Previously I had cycled power on the anybus module and controlnet scanner. LED 5 is still alternating green/red. Is this because 4 of the 5 devices are powered off and not communicating?
Current LED status 1, 3, and 4 are solid green, 5 is flashing red/green, and 6 is flashing green. The 1 active device is communicating.
Thanks
Dean
