CRIO Array to Analog Output

Hello everyone,

I am working with CRIO9074 (mcu side) with the block below I transfer the data  (from lvm file) consisting of "variable and voltage columns" to both the array and the graph with 1 millisecond intervals.

However, when I want to take the data from the array and transfer it to the CRIO analog output, the software cycle slows down a lot. How should I do this?

Best regards..
