Hello together, I've a test bench with one Test station. The test bench includes one test mechanical setup to contact and put strain on the DUT, controlled by a cRio 9045. Data Aquistion is also done via the cRio. The test bench is now being expanded to include three more identical test setups. In advance I'm thinking about the software structure, so that the BD will not to extensive and confusing. There are two approaches I think. 1. I build a few Vi's. One for Data Aquistion, one for each test setup control. But what are the oppertunites to communicate between the Vi's? The test setup has to interact with the measured Data, if there any limits overshouted. The communication should be fast and save ressource. 2. I build one Vi' which contains many SubVi's to keep the BD clear Did anyone have experince what is the best way to handle multiple test setups? Maybe we can discuss advantages and disadvantages. Further suggestions are welcome.

You didn't mention how you connect inputs and outputs of your testbenches to the cRIO. I guess you use dedicated IOs for each testbench!? Like using a NI9205 to measure valtages and using channels 0-3 for testbench1 and channels 4-7 for testbench2? (And the same scheme for any output signals to control the testbenches?) Then all you need is one mainVI with as many "units" as exist in the frontpanel. Each "unit" could be a cluster of IO values. In the background you could use (reentrant) subVIs for each testbench and provide each instance some configuration information about the needed IO channels. (Or you use DQMH and create one clonable module representing one testbench. Then call that module as often as needed.)
