please help to solve the data type problem

[LCHEN5154]

Hello, In short I am building a application to control the NI5154 high speed digitizer. I want to build a master/slave loop to perform the acquisition and

data saving. I need to pass the fetched data array to the slave loop. The data to pass is a cluster which contains a array of "wfm info" cluster and a array

 of "wfmform" cluster. I dont't know how to define a data type which I can wire to the "open/create/replace datalog" function and the "Obtain Queue"

 function.

 I attached the vi and please see the broken lines.

 thanks a lot.

That's simple. Right click on the output of the bundle function and select 'Create Constant'.

Well when you read a datalog file you still need to tell the data type for the function to read data.
