I am trying to communicate with the A2N CPU plc using a usb to DB-9 (RS 232)cable using GX Developer. Am I using the wrong cable.???? or is there something that I should be doing in the transfer setup. Please advise

if you are connecting to cpu directly you will need SC09 cable or it's equivalent. as far as I remember, they use lower speed settings such as 9600bps. transfer settings are under online menu. you might want to change port number since USB<>RS232 converters are usually maped to COM4 or higher and GX Developer's default setting is COM1.
