15.5 GREEN Series Compatible I Relays
15.5.1 Compatibility with GREEN Series Controllers
The map configuration from 1 to 2048 of the I relay map is the same as that of the
GREEN Series (UT700 Series) controllers.
If existing programs created in the GREEN Series controllers are used, communication is
performed using the area from 0001 to 2048.
The I relay map after 4001 is allocated for the UTAdvanced.
If you want to newly perform communication, be sure to use the registers after 4001.
15.5.2 Conventions Used in I Relay Tables

How to Specify I Relay Numbers
When specifying an I relay number for communication, begin the number with the
character “I.”
Example: Set “I0003” to specify the ADERR_E1 (I relay No.: 0003).

Interpretation of Cell
A cell marked with a diagonal line (“ ”) indicates that it is not supported by the
UTAdvanced.

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.
oooo
_Ln Ln : Loop numbers (L1 or L2)
oooo
_En En : Terminal area (E1 to E4)
Example : PVBO_L1 Indicates Loop-1 PVBO.
ADERR_E1 Indicates ADERR in E1-terminal area.
• Numbers in parentheses after the register symbols of the UTAdvanced indicate the
same I relay after I4001.
Note
• I relay numbers 1 to 192 store ON/OFF status information and are normally read for ON/
OFF status information. I relay numbers 1 to 192 also exists in D registers. They have the
same function data as D registers.
• In the area for I relay numbers 1 to 720, 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.
