I have 3 boards in use for around a year, and an event which emails me every time i get a connection error.
---------------
Board 1 is a genuine Uno with a clone Ethernet shield. It has;
2 input pins, and
4 PWM output pins driving FETs controlling 12v LED lighting strips.
This board disconnects and immediately reconnects between 2 and 10 times per day. I could replace the shield with a genuine one and try that.
---------------
Board 2 is a genuine EtherUno with POE module. It has;
1 input,
5 outputs driving heating control relays,
1 PWM output which sets the flow temperature on my boiler, and
1 OneWire pin with 3 temp sensors for my hot water tank.
This board disconnects once or twice per week and then goes Connection FAILED. I cannot reset the board, and have to power it down and back up again.
---------------
Board 3 is also a genuine EtherUno with POE module. It has;
8 outputs driving a relay board;
1 OneWire pin with 6 temp sensors.
This board works perfectly and never disconnects.
---------------
In all cases, the relay boards are driven from a separate 5v regulator, and therefore do not take power from the Arduino 5V line.
Board 2 is causing problems as the heating stops working when it crashes! Any ideas on how to diagnose the issue? The EtherUno is actually a replacement board. Previously I had a normal genuine Uno with a genuine Ethernet shield. I have exactly the same problem on he replacement board.
Here are screenshots of the board configs
Thanks
