Error Code -50103 "Resources reserved".

[Norbert B]

Carnot,

i asume that when you talk about "aiX" you think of the inputchannels
you can connect on the SCXI 1308. these channels are multiplexed in the
SCXI 1100 to a single inputchannel which is acquired by the DAQ-card in
the end. since you create DAQmx-channels for the DAQ-card, i think,
this short  explaination (which in fact is simplified in a certain
way) shows the problem: you want to use the same resource (channel or
better said "functionality") of the DAQ-card in to different programms
at the same time. the driver therefore catches this and creates the
error-message you are seeing.
to solve the problem, you must put all inputchannels in one DAQmx-task.

Carnot,

your solution is working if you do not need to acquire all channels at
the same time (simultaneously). so if it is working for you in this
case, thats fine, except i would advice you to use the errorcluster to
synchronize the vis instead of a sequenxe-structure.

Carnot,

Please refer to the examples delivered with NI DAQ. there you can find
special examples for synchronisation of multiple functions. they should
point out what i meant :)

Hello this example does not do the job because of the bugging error?
