opc server

[arrowminds]

Dear Friends

I have used Labview for small tasks like serial communication, TCP/IP communication and building some graphical interfaces. At the moment, I have to develop an application which involves OPC server. As a newbie to opc server, I have watched couple of webcasts and read some stuff related to opc server. But frankly speaking I couldnt understand the following things in a possible scenario

Scenario

PC A: Labview installed and running OPC server

PC B: Generating some results based on the main hardware

Hardware: Receiving and sending signals from the handheld device like joystick

1)The communication medium used will be ethernet cable and do all of the systems need to be on same domain or work group?

2)How PCB and hardware can find OPC server as they themself are clients.

  I would be very greatful if you guys refer me some tutorials or pdf's which can help me in understanding opc servers.

Regards

Hi arrowminds,

1)The communication medium used will be ethernet cable and do all of the systems need to be on same domain or work group?

>Yes, all systems needs to be in same network/domain 

2)How PCB and hardware can find OPC server as they themself are clients.

>When you connect the hardware in the network and run the following example VI, it will show you all the available servers.

..National Instruments\LabVIEW 2009\examples\comm\opc.llb\Browse To OPC Item.vi

Hope this helps.

I have studied more about opc server and found that opc server needs to be installed on hardware and the PC needs to have Labview DSC.

Infact I am thinking of having real time target module of national instruments which will talk with my hardware. So in this case, can you help me where should be opc server and client.

And how I can National Instruments Real Time target module will find my hardware I/O ports which are having digi serial connector of (Digi Ports 16/EM).

This Digi Ports 16/EM is serial expander having a different kind of connector for output. I will also try to find out connector name.

Hi Arrowminds,

Could you explain your question. What do you mean by "where should be opc server and client"

Did you find the name of the connector? Do you have drivers for the hardware?

Kind Regards,
