Interdependence of Preset Multiple Register Data
Preset Multiple Register data is collectively written only after the query has been determined to be legal,
which includes a range-check of the entire data block. Therefore, data which must be written prior to other
data must use a separate query. For example, a Preset Multiple Register Query of the entire Contiguous
Write Block (40023-40055) to set the Battery Overvoltage Pre-alarm Threshold atop the 24V range and
change the Battery Volts from 12V to 24V will fail. The change to 24V would occur simultaneously to
setting the Pre-alarm Threshold, and the threshold value range-check will use the current 12V range.
Mapping - DGC-2020 Parameters into Modicon Address Space
Current Parameter Table
The DGC-2020 maps all non-legacy parameters into the Holding Register address space (42000 and
above). Query address N will access the Holding Register N+1.
