I have developed a custom OPC client which picks up data from LCN and writes back to specific TDC3000 tags. I want to include an additional point that whenever an OPC Server is writing to LCN it should invoke alarms to notify the operators that OPC Server is writing. Can someone help me exactly In what format the code should be in VB6 and what should be the parameters to be taken from LCN side.

Thanks,
sid

 

Could you please let me know which PC interface card did you use to connect to LCN?

 

Thanks for your response.
Actually I have craeted a DLL in Visual Basic and a GUI in same to demonstrate the OPC client connectivity.

The same DLL is to be used by someone for further programming. The requirement is that we have an ESVT Server with OPC Data Server license enabled.The Level 2 system will be writing back to LCN.

But the request is that the operator shoudl get to know that level2 is writing back to LCN so I want to know how to srtie alarms to level 1 or LCN so that operators are notified. Will it be a point or something.? to be created.

 

Dear sid,

i intend to develop more-or-less same software as what you have developed. i wud appreciate if you guide me towards some ideas? links? sites? guidelines? anything that can help me!

Actually, one of our clients has installed Honeywell's TDC3000. Now our client wants to interface Honeywell's TDC3000 with some open network like ethernet (perhaps to analyze the data accoding to its own needs).

I'll be glad if you can send me any kind of information that may help me develop the software/hardware which can communication the tdc3000 lcn or data hiway?

Thank you,
Kamran

ps: any other techincal information will be highly appreciated.

 

Kamran,

You should have installed APP to connect other systems over ethernet. I'm sure local Honeywell distributor/representative would help you.

Yes! Install APP and write the value you want in a AM point. Then the AM Point can be displayed in the Operator Screen.
