Can both Analog Input and Analog Output function at the same time?

Yes, both Analog Input and Analog Output can function at the same time. However, there will be some minor delays when using the Measurement Manager (AMM) software and VEE. If you are using AMM, you will need to start both functions on different windows which will create some delay in starting time. The same applies to VEE since VEE is running on Flow Chart basis.
