Can I (and if so, how would I) connect two encoders (one linear and one angular) to the same chassis (NI 9401) and get their respective NI MAX tasks to run as simultaneously as possible?

Question

Sorry, but I am still rather new to LabVIEW and NI MAX. I connected both devices (a linear probe and an angular encoder) to my NI 9401 chassis. I figured out how to create tasks for each and get continous samples readings from each. When trying to run both in LabVIEW, I get the error saying that I cannot run multiple tasks at once. It suggests the Control Task VI, but I did not see any help in that. Any advice?
Here is some general information, whatever it is worth: Both encoders are operating off of the same clock source, PFI4, which to my knowledge corresponds to CTR 1 A, where the angular encoder's A signal is wired in. The linear's physical channel is ctr0 and the angular's is ctr1.
Thank you very much for taking the time to look at this and help me out!

Answer 1

So if I go the Edge Counter route, is there any way for the task to figure out direction of the encoders? It looks like my options are always counting up or always counting down whenever the encoder is read... For my application, I need it to read when the linear encoder goes in and when it goes out... Am I doing something incorrectly with it?
I am using a probe to measure the contour of a part, and using a motor to spin the part, with one encoder measuring the angle of the motor and the other measuring the displacement of the probe.
Also I am still not seeing a way to simultaneously read both devices in NI MAX... I cannot use two counter inputs from the same device at once in the same task it seems.
