Dear.
I'm learning how to handle analog signal (Analog Input signal and Analog Output Signal) using ladder language with GX developer 8.0.
Now I have Q02HCPU Melsec PLC.
Please help me.

(if you have any ebook that show how to program Melsec Q in ladder language or if you have a progam dealing with this issue please share it to me).

Thanks.
