1. What is the setpoint in a control chain?
   1. The desired value for a specific process variable 
   2. The calculated value for the control variable fitting the reference value 
   3. The measurement of the process value coming from the process 
2. What is the accuracy in a sensor?

10. What is the best definition of an asset model?
    1. The asset model is the conceptual model of the physical or logical assets that the company uses to perform its business 
    2. The asset model is the master data of a MES system
    3. The asset model is the logical model that allows for the exchange of information between the MES and ERP system
