measuring encoders using PXI-6602 in LabVIEW Continuous Measurement Sample Project

[Joseph@EM32]

i'm trying to read position data from 4 linear encoders connected to a PXI-6602. i'm also trying to use the LabVIEW "Continuous Measurement" sample project. i have been trying to use a dummy analog input task to start the timing. i keep getting errors like Error -200216 which says that i cannot used interrupts or DMA for the data transfer mechanism. i also get error -200557. but i think that i know how to solve this error. i can provide a copy of the sample project that i have modified or just the counter vi's that i have developed.

Please share your code, preferably in version 2019 as most forum users don't have access to the latest version.
