Mitsubishi PLC Ethernet with VB.net

Hi,
How do I pool PLC's data memory with vb.net via Ethernet?
I have an Aseries PLC with A1SJ71E71N ethernet module. I am trying to develop something with VB.net to pool PLC's data memory.

So far,I have the Ethernet module's manual, and it has settings in ladder diagram for connection purpose only.

What do i need to do with vb.net to pool the data from the PLC?

Thanks !

Maybe Look at this !!

I'm not sure about Mitsubishi, but I'm using a sweet package for the AB PLC. Using Visual Studio 2005 express, (free) with the Ingear ABlink software, I've made a nice data logging program for monitoring and storing data over the company network.
The site is http://www.ingearnet.com. Maybe they plan to add support for the Mitsubishi, I hope.

Good luck,
Terry

well you could write your own OPC Server in VB or you could buy one... And then only write a opc client to connect to the server and read / write values...


Here is an example (beijer) of how to do a OPC Client (but its made in VB6 (sorry)) but if you google OPC client + VB.Net you may get some answers...

Kepware also have a nice download(to the .Net platform), KEPServerEX OPC Server (Super Server Pack).

"The Server Super Pack (SSP) contains the latest version of KEPServerEX, all of our currently available OPC Drivers, the full featured OPC Quick Client, Comprehensive Visual Basic examples, and more all in a single download."

Go to Download and create a account and then you will find it...

contact Mitsubishi and ask about MX Component

Thanks for the reply everyone, finally I bought Mitsubishi MX Component for USD$500.
Just add mitsubishi component reference into the VB program, follow the example and the rest is as easy as A B C.
