Overview

IM 05P07A01-01EN
This chapter describes the functions and applications of the D registers.
D registers are used in Modbus, PC link, ladder, Ethernet communications, or Open
Network communication (network profile creating function of LL50A) and are used for
storing UTAdvanced parameter data, flag data, process data, and other data and values.
The host computer can utilize these data by reading from and writing to the D registers.
When you newly perform communication with the UTAdvanced, the D registers after
D2001 are used.
Use of the D registers enables the following:
 Centralized control by the host computer
 Reading and writing of data between the UTAdvanced and the host computer
Note
The D registers available vary depending on the model and suffix codes of the UTAdvanced or
parameter settings. For details, refer to the respective UTAdvanced User's Manual.
D registers and I relays oh the UTAdvanced are used for parameter settings or ladder
program creations of LL50A Parameter Setting Software.
