Posted 6 May 2015 I'm having trouble communicating with my PLC. I have an CQM1H-CPU11, I'm using a USB-CN226 cable. I installed the driver that came with the cable. If I try to go online, it pops up "Failed to connect to the PLC." My dip switches are currently in the the positions of 1 off, 2 off, 3 on, 4 off, 5 off, 6 off, 7 on, 8 off. Any help would be greatly appreciated! Share this post Link to post Share on other sites
Posted 6 May 2015 Dipswitch 5 is off which means serial settings according to user setup, if you don't know these I suggest to put dipswitch 5 to on and select Toolbus, 9k6, 7,e,2 in CX-Programmer. CQM1 Dipswitches.pdf Share this post Link to post Share on other sites
Posted 6 May 2015 I changed the dipswitch 5 to on, and I had no change.... The pic of the "PLC Change with Network Settings [Tool Bus]" I'm not sure how to pull that up? The CX-Programmer Version I'm using is 9.0. I've checked the Device Manager on my PC for the driver and there doesn't seem to be any problems there... Is there any thing else I can try?

Posted 6 May 2015 Well setting Dipswitch 5 on alone is not enough, you have to make sure the settings are as in the picture, and select the correct COM port. To pull up the settings see below picture. 1 person likes this Share this post Link to post Share on other sites
