dear bnemmers,

I see
I never used OPCs but I think I can not find my need in an OPC site.becouse I see almost every OLEs in that site are complex components not for example a gauge.

I will be pleased to know more about you.have you ever use OPCs? are you a control Eng(or student of control Eng.?

best regards

Yes, I'm a controls eng. and sys programmer.
I've spent the last 5 years in the MES area.

I've used OPC for reading and writing to PLC, SCADA system
I use AB PLC mostly but I talk through RSLinx OPC server
which you can use with many PLC's.
Also I used OPC to create a Client/Server to work with DeltaV system, etc..

Delphi is a great tool when working with OPC & DTL.
because I placed most of the OPC stuff in NT server apps.

Good luck and happy coding.
Bill ;)
