Communication

[rswolff 9]

Have an FX3G......GX Developer 8.114U.......tried connecting using a USP-SC09 cable. Sometimes it would say connected and know which processor it was connected to (tranfer setup), but I could never go online (read/monitor).....if in tranfer setup if I used Connection Test, it would say connected 2 or 3 times and the say can't communicate or data error. Any help appreciated. Thanks, Bob NO ITS NOT A NOISE ISSUE SO DON'T GO THERE. I used the SC09 several months ago with an FX0 and no I don't have a spare Mitsubishi plc (I don't use them)

On a customers laptop years ago the only way I got an SC-09 with a 232-usb converter to work consistently was to lower the baud rate in the transfer setup in GX-DEV. Is this a "3rd party" cable?

I had that problem a couple of years ago with one of the FX-USB-AW converters from Mitsubishi connecting to an FX3U using some version of GX Developer 8. The connection test said it could see the processor, but I couldn't get online. I finally switched to my trusty 3rd party serial SC09 and a USB to serial converter, and went right online. That was the last time I tried to use the FX-USB-AW. It's still banging around in my bag. I'd recommend just trying another cable. You could just use the mini-USB port on the front of the PLC. I've had patchy success with USB-to-brandXPLC communications cables. I find my trusty USB-to-serial adapter to be more reliable, and I only have to deal with one set of drivers. Plus the basic serial cables are usually cheaper or a duplicate of something I already have.

yes....its a 3rd party USB-SC09-FX cable.........I reloaded GX-Developer but I won't be able to check for about two weeks when I return to client........yes, I could do a USB to Serial converter but I'd also need a standard SC09 which I don't currently have......and I could also try without the converter since my laptop has a serial port (pcmcia slot too!!!!).......and I can try the mini-USB.....didn't have a cable with me and client couldn't locate one in the office....I'll bring a ton of h/w with me when I return....just wanted to make sure I wasn't missing or doing something stupid. Sounds like it could be a driver issue since you both indicate some similar issues.....thanks for the help....

Hi rswolff, Remeber to install the Mitsubishi USB driver if you start using the mini USB port. The driver is allready present when you have installed GX-works2/GX developer software on the harddrive of your laptop. Check this locaton: C:\Program files\EZsocket\Easysocket\USBdrivers If you goolge a little bit there are YouTube movies that shows how to install this driver. Best regards, Theo V.
