I have a modbus device that I'm controlling everything works the way it should. I'm polling the device every second. The HMI freezes every minute or so and it stays that way for a minute. When I look at the wireshark capture I can see the modbus device send a (FIN , ACK), the HMI responses with and ACK then keeps trying to poll the device. Can you tell me if there is a way to adjust the modbus driver or the code to get it to re-connect after the device closes its connection.
Thanks
