7.5 GREEN Series Compatible I Relays
7.5.1 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 (UT500 Series/UP550) 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.
7.5.2 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.
