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 ME-NET. However the TMR/CNT contact points correspond to the even addresses from 16000 to 17777(8).

-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.

-Relay addresses 07300 to 07377(8) and 15760 to 15767(8) in the JW20/JW20H are special address ranges for relays.

-Available addresses vary with PC model on which the JW-21MN is installed and its capacity. For details, see an instruction manual for each PC.
