Specifying the Register Number
Specify the register number on the FX by using the “reference number” (such as
the number 40001 written above). For example, for the YOKOGAWA UT35A digital
indicating controller, the D register number corresponds to the reference number as
shown in the following table.
D-Reg. No. Ref. No.
D2001 42001
For a server device that calls the register using a “relative number,” add 30001,
300001, 40001, or 400001 to obtain a reference number.
