8-2 Memory addresses for computer links
-Data memory byte addresses in the computer link must be entered the same way a data link address is entered.
-The relay numbers and TMR/CNT numbers are the same for the
-Program addresses correspond to addresses of file (SEG)8.
For details about the detailed addresses to use on the host computer, see the instruction manual for the host computer.
