Dear all,
I have fx3u series plc with built in rs422 port and usb-sc09-fx cable. I have a a hyperterminal like application to send and receive message between the pc and the plc. I know the cable work because it is fine when I load the ladder from gx work 2 to plc and when I read back. I used a simple ladder using RS instruction with non protocol communication given as example in the plc manual. But I can not communicate with plc. I have checked the baud rate and related things but still I didn't get a solution. Please help
