Vega VEGAMET 624 - Page 7

always sorted according to PC/DCS output number. The
following chart shows the addressing of the temporary memory
via Modbus. The values are accessed via FC 3 and 4. The
status information is also transmitted as float value. 8 byte are
needed for one output, corresponding to 4 registers.
Information:
Note: A float value comprises 2 registers, i.e. a total of 4 bytes!
