Keyence tech support doesn't have anything? I would imagine that they would normally have at least example programs for each of their products.
What kind of connection is this vision system using?
I'm using Ethernet/IP for both 2D&3D systems via hub. I contacted Keyence tech support. Turns out the sample .pc program for both systems are the same, and I could just use arguments for each .pc program to change between clients. ( which was not stated in the Keyence website's free user manual ). Anyway, the system's running fine now.
