Im trying to intergrate a Coolmay TK6070FH HMI Touch Screen via RS485 into Node red to display system status
I have not been able to find much info and the stuff i found had no resolutions.
This is my Flow todate
I have connected a serial port into the Modbus Flex Server and for the reply the same port on the output side
my first issues looks to be the serial port is not getting the data via the USB serial port.
Note I have checked the port USB_P5 works by using it to read a Modbus relay module, This works with out issue.
I have included my Flow below for reference.
The Modbus Flex write is used to write data into the Flex server, (this Node is work in progress)
