Siemens s7-200 PLC & Visual Basic
Siemens s7-200 PLC & Visual Basic
(OP)
I'm new to all this so bare with me...
I have a Siemens S7-200 series with a network module up and running and doing what I need it to do. Now I'm trying to write a Visual Basic program to access some of the memory locations so that I can do some DHTML programming...
I know there is an Alan Bradley plug in for VB that you can purchase to communicate with their PLC's. I've called Siemens and the only response I get out of them is they don't support Visual Basic. Does anyone know if there is a way to make Visual Basic talk to a Siemens PLC?
Thanks!
OR
A way to publish some data stored in the memory locations of a Siemens PLC into an HTML file. I know you can get an internet module, but I'm trying to gather a bunch of information from many PLC's. I would perfer to stick with VB...

Of course Siemens don't support VB, it is obsolete!
You don't say which network module you are using, The CP243-IT module already has a webserver onboard, so you can use HTML directly, embedding java applets allows direct access to all the memory and IO images. there is an online demo at http://s7-200.germainesystems.co.uk.
If you are using the CP243 then consider Libnodave, this will also work with the serial ports on the CPU. - I believe that it supports legacy VB too :) it's open source and free at http://libnodave.sourceforge.net/
