Support Questions / ModbusTCPCom not restting

« on: August 22, 2018, 02:38:29 PM »

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

Support Questions / Write Multiple holding register with modbustcp

« on: August 20, 2018, 02:05:47 PM »

Hi,

I'm trying to write a block of 63 registers. I have an array of integers setup. I can't get the right conversion to string to work with the modbustcpcom1.beginwrite statement. Basically I need to go from 16 bit unsigned integers to  string to be able to write.

Thanks
Mike
