how can i transfer the data to the iFIX application?Thanks

[lct0811]

I have writen a program to sample the data via RS232, I can save the data in the txt file and display them in the control of Table!

Now there is a task that i must transfer the sampling data to the application of iFix.

How can I complete this task?

Can DDE  realize this project? If yes ,how can I do that?

Thanks

For iFix the data (which is transferred by DDE) can be add by this form:

‘ABCNDDE$’|‘DMDATA.DDE’! ‘SCADA1.AI1.A-CV’

ABCNDDE is the name of .exe file

DMDATA.DDE is the panel name of .exe file

SCADA1.AI1.A-CV is the control name of the .exe file

there is a successful application for this task ,the sample software is produced by VB6.0...  I will add some other channels to sample the field data , so i will realize this task by CVI.

In the VB6.0 the .exe file name is  ddeserver.exe   THere is a panel named as "ddesv"  to display the data sampled . There is a text control named as "text1" to display the data.

‘ABCNDDE$’|‘DMDATA.DDE’! ‘SCADA1.AI1.A-CV’  is written as  "ddeserver|ddesv|text1"  more or less.(I will check the exact synax later)

Similar to the sample program written by VB, How can I written the ‘ABCNDDE$’|‘DMDATA.DDE’! ‘SCADA1.AI1.A-CV’?

my sample program written by CVI is named as TPG.exe

the displaying panel is named as Panel

I use a table  control to display the data. And the data is at row2 column 3.

the IFIX reference is as below:
