5 Working Principle
Inside the gateway it opens up a length of 5000 bytes of memory as the data exchange of input and output
buffers. Memory of 0 to 2999 acts as the storage area of the HART input data and device status. Memory of 3000
to 4999 acts as storage area of the HART output data and control variables. The specific assignment shown in the
