What was the logic change?
Looks like there was a fault generated during the download and the Modbus card is not responding or faulty, this in-turn has halted the controller and the OPC service.
Physically check the status of the card, if in fault remove and re-insert and check if the fault clears.
Contact or raise a support request with log files.
