Hello, I'm planning to use a NI DAQ-card (PCI-622x) with Xenomai and Analogy.
The idea is to synchronize a camera setup with a robot. The robot is controlled via UDP-packets that are transmitted periodically with a cycle-time of 1 ms. The initiator of this communication is the robot controller (KUKA FRI setup with LWR 4+ robot). With every 20th datagram a camera setup shall be triggered via the DAQ-card. The delay between the data-transfer and the trigger-activation should be minimal or at least known with a reasonable small jitter (magnitudes smaller than 1 ms). But before buying the card I'd like to have some information about the timing-performance of this setup: 1) What execution time (or magnitude of execution time) for DIO, especially output, from command execution until change of signal on the output can be achieved? 2) How much jitter in this execution time can be expected?
