terminal status
DI terminal
Each bit information is the same as that of
D register.
6433 to 6560 DO terminal
Each bit information is the same as that of
D register.

Note 1: SP numbers are for UT35A/UT32A, and Pattern numbers and Segment numbers are for
UP35A/UP32A.
Note 2: These are for UP35A/UP32A.
CAUTION
• Check the model and suffix codes and parameter settings before writing to or
read from the registers to be used.
• In the area for I relay numbers 4001 to 6560, it is prohibited to write data
to I relays with blank cells in I relay map tables. If you attempt to do so, the
UTAdvanced may not operate properly.
Note
• I relay numbers 4001 to 6560 store ON/OFF status information and are normally read for
ON/OFF status information.

How to Specify I Relay Numbers
When specifying an I relay number for communication, begin the number with the
character “I.”
Example: Set “I4065
”
to specify the ADERR (I relay No.: 4065).

I relay symbol
• With regards to some register symbols, the loop number and terminal area are
indicated by adding the underline (_) to the end of the parameter symbols.
Note
Since the UT35A/UT32A is a single-loop controller, it has no distinction between Loop-1 and
Loop-2.
However, the register symbol has "L1" which indicates Loop-1.

_En En : Terminal area (E1 to E4)
Example : PVBO_L1 Indicates PVBO.
ADERR_E1 Indicates ADERR in E1-terminal area.
