how to get started using VB6 to program HMI's
(OP)
Hello!
I was wondering if anyone had some tips on how to get started using VB6 to program HMI's. I have lots of PLC and HMI experience. I understand how you create display items for variable set points, but how does the data get to the PLC?
If you know of a good tutorial let me know!

Give this a try:

http://sourceforge.net/projects/advancedhmi/
It's based on VB.NET, is all free, and will get you making HMIs in minutes.

I'm thinking that we'll probably put a new SCADA front end on this system. So, a couple of questions for you:
1. I have a SLC5/05 with built in ethernet. I assume that this VB.NET application handles TCP/IP as well as serial(?)
2. How would you expect the performance of the workstations to be if I had 3 operator stations? Like I said, my current 3 station architecture is pretty slow. If I drop the stations back to a single workstation, then performance is reasonable. I've already optimized the network too so that there are no other conflicts.
Thanks

The performance is dependent on a lot of factors such as how many registers you will be reading and if they are consectutive in memory. The AdvancedHMI driver will be able to outperform other drivers, such as OPC, since the driver is compiled directly as part of the application.
