800xA PLC Connect Modbus TCP/IP Configuration
The minimum number of holding registers (HR) is 16. Is it possible to read a block of modbus registers that is smaller than that value? If I create a controller and add 4 tags (reals) for a total of 8 registers the comms fail. I assume this is because my total register count is less than 16. See attached screen shot. Thanks in advance for any help.
