10.3 Classification of D Registers

Classification of D Register Map Tables
The table on next page outlines how the D registers are classified by their numbers in the
D register map tables.
When you newly perform communication with the UTAdvanced, the D registers after
D2001 are used.
CAUTION
• Check the model and suffix codes and parameter settings before writing to or
read from the registers to be used.
• No data can be written to or read from blank parts of the data storage area by
communication.
The UTAdvanced sometimes does not operate properly if an attempt is made to
write to or read from blank parts of the data storage area.

Setting a Value with a Decimal Point
When setting a value with a decimal point from the host computer, set a value
excluding the decimal point (hexadecimal)*.
Note
The UTAdvanced determine the decimal point position by the parameter setting.
Example: When setting a target setpoint “50.0” from the host computer
Set “1F4” which is a hexadecimal value of “500” (50.0 excluding the decimal
point) (this is also true for setting 5.00 or 500).
Target setpoint “50.0”: P.DP = 1
Target setpoint “5.00”: P.DP = 2
Target setpoint “500”: P.DP = 0
*: For ladder operation, set the BCD value excluding the decimal point.
