Program 2 FX3G PLCs from one 'puter via usb?

[larry818]

Hi, I've got two FX3G PLCs that I'm developing code for and I'd like to program them from the same PC (simultaneously, not by swapping files & cables). Both PLCs are connected by USB, and I'm using GX Developer 8.9 something. Is this even possible? The manual has diagrams that say both yes and no. Thanks, Larry

To throw a question back; how will you distinguish between two FX3G's from GX Developer? Where do you set any variables that indicate a unique value for each PLC? I'm pretty sure you cannot do that, though I must admit I haven't read the manual on the specific topic.

I guess that's what I'm asking. I have two plugged in now but nothing jumps out at me. I think I'll have to do one by serial.

Cannot have more than one USB plugged in at once. The software cannot differentiate more than one connection.
