Hello all, I have two scenarios i am looking to find answers for. I had an old laptop that the serial port stopped working on so i purchased a Dynex USB to Serial adapter which worked just fine for a short while. After using for a couple of weeks I all of the sudden would get a blue screen of death pop up for a few seconds after 3-5 minutes of being connected to an active PLC and the laptop would shut itself down. Figuring it was the cheap Dynex adapter I purchased the EA-PGM-CBL adapter, but the problem still persisted. After some crying to the boss, figuring the laptop was on its last leg, the company recently purchased me a brand new, fairly higher end Dell with Windows 10 PRO. The old problem has gone away, but two new ones have popped up. 1: If the cable gets right next to a functioning GS1 drive it sometimes (not always) will lock up DS6. 2: if there is a rapidly firing motor starter or relay, say like in a bump starting situation, it will also lock up DS6. In both scenarios I have to close all programs and restart my laptop and reopen the programs before I am able to reconnect again. COM port becomes unavailable. I am connecting to either a DL06 or 250 with the EA-PGM-CBL on either COM port 3 or 4. I have tried both to see if it made a difference, but it has not.

Dell laptops are not high on my desirability list for industrial duty. Their touchpads have been very prone to erratic behavior around VFDs and Static Eliminators. It is pretty disconcerting to have your mouse pointer moving itself around and clicking things all by itself. It has definitely been a Dell "feature ". I'm not sure if my newer one is as bad, but that may be because I use an old Gateway most of the time simply because it is rock solid around electrical noise and I love its touchpad.
I have no idea if this is related to your issue.

Get rid of the Dynex USB to serial converter. I saw the same thing on a customer PC when upgrading the OS and the proper driver not installed. Buy one of these:

I prefer Windows 7 over Windows 10, but sometime all too soon, I will be forced to surf the bleeding edge too. I like Dell Latitude laptops for a reasonable compromise between price and durability. Everyone has their favorite. I am going on two years and 90,000 truck miles on my Latitude with no problems. I am still able to buy Windows 7 Pro on the aftermarket and MacroShaft claims they will support it until 2020. Hopefully 3 more years is enough time for all the software I need to be fully debugged and operational on that OS. I wouldn't hesitate to spend a hundred dollars to revert a new PC to Windows 7 Pro.

I think a better quality converter will help, but it is a good idea to keep the sensitive cables away from high voltage and especially VFD motor leads. Have you ever looked at a VFD "waveform " on an o-scope? Understanding induction and seeing that will help you understand why there is a whole marketplace for VFD noise mitigation products.
I try not to put any PLC in the same panel with a VFD, but if forced to do that, I always try to make sure that the spacing is as good as possible, especially with the VFD output wiring.

I 've noticed the same thing with a Dell laptop I have at work. Does it to a lesser degree on a Asus laptop I have. I made a new d-sub to RJ11 cable out of 26awg cable with a braided shield, and the two times I 've used that cable in a cabinet with a GS3 and DL-06 I didn't have any problems. The Dell laptop was unusable on a test bench I had set up with a H2-DM1E and Yaskawa servo when hooked up over ethernet or usb.
