code not working - soccer - 05-08-2023
Could someone tell what is wrong in the code? it's not working with a hmi delta dop-107EV, I don't know what could be an error in the code.

which board you are using? which communication port you are using? should have details of question.

I'm using the kc868-A16 board, I'm using the ethernet port for communication, through modbus tcp/ip, so it's not working, and I don't know why. would the code be incorrect?
RE: code not working - admin - 05-10-2023
it's not easy to say. you can test with two step:
1. ethernet whether work well.
2. modbus protocol whether work well.
