Synchronously control several hardward

[飘零]

In my VI , there is a Flat sequence structure. In the first frame, three VIs to be run , they are D1(to read date from hardware1's data1), D2(to read data from hardware1's data2) and T(to read data from hardware2's temperature). In the second frame , I use the D1 and T to make up of spreadsheet D1~T, similarly the spreadsheep D2~T, and then portray their graph by the Express Graph VI.

Then the problem occour , it is  error 1073807339. As I know the error offen cause by "timeout  before operation complete" but I have not any problem in using the three VI D1.vi D2.vi and T.vi one by one.How can I solve the problem?

Thanks a lot!

Can you make your VI run in highlight mode to check at which node does the error occurs?

Acutally, this error usually happened with VISA Write.
This error usually occurs when you are writing large amounts of data. You will receive this error if it takes longer than the default timeout to send your data. The easiest solution to this problem is to increase the default value for your VISA Session. You can do this using the VISA Set Timeout VI located on the VISA Advanced Pallet in LabVIEW.

Maybe the same reason for your application.
