TCA9548A I2C multiplexer with Ni-8452
I recommend a slightly different approach. Use a FOR loop. This would make it expandable to the number of sensors you are using. The idea is to set the MUX channel, and then get the data from the sensor. You can repeat this any number of times as needed.
The idea of using the error wire is to use Data Flow to set the order that things happen. You have to set the mux channel before you can talk to the desired sensor. Because of this, you cannot talk to another sensor under the first sensor is complete.
