VB communication component

[Sergiopd]

Hello,

A few months ago I've used a visual basic component (ocx) to make a ethernet link between my application (made in VB code) and a GEFANUC 90-30 but that was expensive enough to make me think about another choice. Does anyone know a free visual basic component that would allow me to make an ethernet link between the PC and a GE or Allen Bradley PLC?

When I was in my early teens in Columbus Ohio a neighbor and I filled a box with dog poop, wrapped it in wrapping paper, put a big bow on it and left it on the sidewalk to see what would happen. Eventually someone came along and discovered the find and brought it into her friends house. A few minutes later she came running out of the house frantically wiping her hands.

Moral of the story, you don't get something for nothing.

This said, I recommend paying the $600-$800 price tag for an activeX or OPC server. You'll save yourself a lot of headaches, have a complete protocol command set, and save money in the end.

Automated Soloutins has an ActiveX for GE Ethernet. You can download a demo here:

They've also got ActiveX controls for A-B.

For an OPC server, check out Kepware or Matrikon. For A-B you can use RSLinx OEM or better.

Good Luck,

We always use the winsock component to connect with our Festo PLC's. Both UDP & TCP protocols can be used and it's easy to configure. If you're using VB6 I can have a look if I can send you a small example program with WinSock communication.
Let me know!
