The PLC controls and monitors my solar heating system, a secondary heating circuit with pumps and ventilation. In addition, temperature outside, inside, etc. is monitored.
The PLC disconnects at varying intervals, typically 1 to 3 weeks. There are no error messages in CBP after reconnection, and it all runs normally again. The error has been there for some months and I have not noticed if it has started in connection with changes I have made. In the past, with similar frequency, there was an error message on an analog input, but a new transmitter cleared this problem some time before the disconnects began.
I noticed that "Transmit throttling state is:" Inactive, faulted "in Onboard Ethernet throttling ststistics. Can the CPU be upgraded, or otherwise?
The corresponding Receive Throttling state is "Active".
