After the long uptime (50 - 100 days or more) server (windows) are stopping to send commands to the HDL BUS. Commands are received from the panel. Log writes that channel 13 (or something else) is changed. But HDL BUS not responded. Feedback is still zero.
Restarting server application make it work again.
Server version 18.104.22.168
