Reducing Communication Time for High-Speed Control with PXIe-8861 and I/O Modules

[Rez_konj]

I am attempting to utilize the PXIe-8861 in conjunction with the PXI-7604 and PXI-6363 I/O modules to manage a system. Despite the fact that the I/O modules possess a 1 microsecond response time, it appears that the communication between the module and the CPU takes around 1 millisecond. Is there any way to decrease the communication duration to a frequency below 1 kilohertz? Thanks,

Why do you need low latency? you may have to rethink your application architecture.

If you need ultra-low latency you need to implement your application on an FPGA and not an OS-based system.

The driver layer and OS will definitely hinder your latency.
