Say I have a cdaq with 1 analog output card and 1 digital output card and I want to use these cards in a state machine (in labview) with different states doing different things - perhaps one state allows the user to issue manual analog output commands and manual digital output commands on a subset of channels and another state generates waveforms that are output to all channels on both cards. The only way I've been able to do this is to place the create task, configure task, timing, write, start, stop, and clear functions inside each specific state (so it fully creates, executes, and clears the task before going back to the "waiting/idle" state). If I try to create a task using all the channels outside of the state machine and then just start/stop inside the state machine states I get an error about resources being reserved. Is there a way to create global tasks that contain all the channels I'm interested in using outside of the primary state machine and then "reconfigure" the task (or perhaps this isn't the correct terminology) in each state machine state so I can just configure, start, write, and then stop the task without having to also create, set timing, and clear the task as I'm doing now?

Task/Channel Reconfiguration in State Machine

Attached is the latest version with a bunch of the suggestions you guys have made incorporated (or at least to the best of my abilities as a labview rookie!)

Thanks all!
