Hi,

I am using DELTA PLC. I want to pick up the hi speed counter value from PLC. The data I am getting on Modscan software. But how should I get the data in vb 6.0?

Presently I am breaking my head on this same topic. Delta connects on Modbus OPC, so thru this you can get data in VB. It is also possible to link using DVP protocol developed by Delta which is closely simmilar to Modbus. I could read/write on this protocol thru Hyper terminal. Now next step is thru VB.

Read Delta PLC's protocol document and InTouch connectivity document ( Available on Delta's site for free download). If you successfully do this pls inform me too.

Thanks and regards,
Shriram Pendse

Well,
As Delta PLC supports Modbus, it is very easy to Connect it to VB application. delta site now has posted sample code for this, it works, I have already used it in my VB based SCADA.

Hi,

The most reliable way to integrate Modbus communication in VB is to use a professional ActiveX control. You can visit http://www.automationcorner.com or http://automationcorner.wikispaces.com

Hello!
you can communication with Delta PLC use Delta Modbus DLL Library. Maybe you can find it in this path.

http://www.delta.com.tw/product/em/download/download_main.asp?act=3 &pid=3&cid=1&tpid=3

when you install it, you can get sample about communication code (vb code). if you don't find it still. then give you my bolg path. you can download it in first page. but my bolg's language is Chinese format.
