hi experts,

I need Some gauge Components ( Analog with pointer or Digital with 7-seg ). for example for use as Pressure gauge or humidity gauge and ...( thay are only for monitoring )

Do you Know any Site with Free ActiveX or Delphi Component for this application. There Is some OPCs ( OLE For process control ) for it. but I didnt find any Free Version.

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

dear bnemmers,

I see http://www.opc.dial.pipex.com/delphi.shtml.
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
hamed

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 ;)
