Error -200022 on NI-9401 with DIO and Clock Task

[QRP]

Could someone kindly look at this VI and explain how I can resolve getting the reserved task error of - 200022? The VI sets up a clock task to monitor motor steps and another task to monitor inputs from the motor on the NI-9401. There has to be a way to do both tasks together I would hope somehow without this reserve error showing up. If not, how would I manage to do this differently?

Thanks.

BTW, the NI-9401 is being used in slot 3 of the NI-9188. I hope this helps to answer my problem. Thanks again for any help.

Is this question really that difficult that no one knows how to resolve it?

You are getting that error message because you are accesing the same resource for two different tasks.

error -200022

To run your VI there is needed the emaxState.ctl. I got broken arrow.

Thanks. Yes I realize what the error is, but need to know how to resolve it. I'm currently using cnt1 and inputs 4-7 on the 9401. Would moving the counter down to cnt0 and leaving the other inputs I need on lines 5-7 solve the problem since they would be on difffernt nibbles of that port or would this still throw the reserved error? I attached the missing .ctl file so you can run the VI and maybe help me reconfigure the port setup so I can have a counter with inputs I can monitor on this module.

Thanks so much.

-          When I ran the VI I got error -200463. I could solve that issue changing in the DAQmx create channel the input line grouping to one channel for each line.

-          Then I ran the VI and I got error -200022. So as workaround you need to change the counter (ctr0) if you are using 4, 5, 6 and 7 as digital lines. However if you make that change you are going to get error -201133. Check the link below to solve that issue:

Thanks. I wondered if using the counter task on the same nibble of the port as the input line task would cause a conflict. I actually moved my inputs up to Line0-2 and left my PWM line on Line 4 keeping the counter at cnt1. I reserved the counter task, then started the input line task for lines0-3 then started the counter task and it all worked! Thanks again for the heads up on the 201133 error too.

Thanks again.
