(3) Holding Register (Set Data)
(1) Time setting value
This is a set of four registers used by the DCS to set the device clock. When the time
setting request coil (address 00003 for GC1000 Mark II and GCIU, 00001 for the
analyzer server) is activated, these entries are used for the year, month/day, hour and
minute/second. Since all devices on the highway synchronize to the analyzer server
clock on a regular basis, the analyzer server clock should be regularly set.
