Using the headless HMI with my modbus device
I have a modbus device from a third party I want to use with the C-more headless HMI. I need some help connecting to the device.
im a contractor that builds out grocery stores. We see the C-more headless HMI ideal for refer and freezer temp monitoring.
my account is under Advanced Rooftop Controls
thanks in advance.
you can view the modbus RS-485 device here:
the device is the IO-12
I do not see any sort of Modbus Register Map. Do you have a manual that shows this information?
