DCS value is represented by two words. T he first word
contains the real PC/DCS value, the next higher word the
corresponding status information. In the specification the term
register word is also used instead of word.
The filing of measured values in the temporary memory is
always sorted according to PC/DCS output number. The
following chart shows the addressing of the temporary memory
via Modbus.
