Hi all, I'm experiencing an interesting phenomenon and was wondering if anyone more wise than me could explain it. I'm running a trial of KepwareServerEx over ethernet to a Melsec/A PLC. I've finally gotten that part working (by using UDP instead of TCP as I found in a forum today), but while testing everything I've found that if I go online with the PLC through the serial connection that I'll start getting communication errors in Kepware. I thought maybe it was an issue with having two connections from the same PC, so I installed Kepware on another computer to see if I could recreate the event and as soon as my laptop completed connecting the error started showing up on the desktop. The error comes up saying the device is not responding. I had it come up twice after making the connection with the desktop PC prior to going online from my laptop, and once I was connected it showed every 2-6 seconds. If anyone has some ideas I'd love to know what to try.
