This video will walk through our Week 5/6 lab in which we have calibrated a DP Cell to output a 4-20mA signal corresponding to 10-50 cm in the tank.
Next step is to create a PLC/HMI program to display the values coming back from the sensor and allow us to control the 0-5 V DC signal to the pump vfd.


This video will walk you through how to display the identical 4-20 mA current within your PLC program using the NORMx and SCALEx functions.


Note: Actual code for those not in our class starts at 26:00
