This set of Flexible Manufacturing System Multiple Choice Questions & Answers (MCQs) focuses on “Discrete Process Control”.
1. Which control systems consist of variables and parameters that are discrete in nature?
a) Arbitrary process Control
b) Discrete Process Control
c) Numerical Process Control
d) Transmission Process Control
View Answer
Explanation: The control systems which consist of variables and parameters those are discrete in nature are known as Discrete Process Control. These control systems change value at discrete moments in time.
2. What type of variables and parameters are used in Discrete Process Control?
a) Ternary
b) Quaternary
c) Unary
d) Binary
View Answer
Explanation: The variables and parameters used in Discrete Process Control are usually binary in nature. These binary variables in discrete process control system are associated with the signals transmitted to and from the controller.
3. Binary Variables have only one possible value.
a) True
b) False
View Answer
Explanation: Binary Variables have two possible values. They are 1 or 0. The values differ according to the applications they are used like ON or OFF, object present or not present, high voltage value and low voltage value and so on.
4. Which signals are generated by binary sensors?
a) Input Signals
b) Modulated Signal
c) Output Signals
d) Built in Signal
View Answer
Explanation: The binary sensors generate input signals. Typical applications include photo sensors and limit switches which generate input signals are then interfaced to the process.
5. Which signals are generated by the controller?
a) Output Signals
b) Input Signals
c) Nodular Signals
d) Bipolar Signals
View Answer
Explanation: The Controller generates Output signals. The function of this system is to operate the process in response to the input signals. The objective of the system is to perform with respect to time.
6. Which of the following is used to coordinate the various functions of a physical system?
a) Controller
b) Moderator
c) Vibrator
d) Coordinator
View Answer
Explanation: The various functions of a physical system are coordinated by the controller. Transferring of parts into a work holder and feeding a machining work head are the typical applications of a controller in a controller system.
7. How are Discrete process control system classified?
a) Intermittent and Distributor Control
b) Logic Control and Sequence Control
c) Machining and Operator Control
d) Binary and Algebraic Control
View Answer
Explanation: Logic Control and Sequence Control are the two broad categories of Discrete Process Control. These systems are operated by turning on and off the switches. It is operated in response to the operating conditions.
8. Which of the following is carried out by event driven changes in a system?
a) Logic Control
b) Sequence Control
c) Data Control
d) Event System
View Answer
Explanation: Logic Control System is carried out by event changes in the system. It is also termed as Combinational Logic Control. The Output from this system depends on the system inputs which is accomplished through switching system.
9. Both Logic Control and Sequence Control systems are referred to as switching systems.
a) True
b) False
View Answer
Explanation: Logic control and Sequence control systems are both termed as switching systems. This is because of the usage of the switching systems which are used to switch their output values on or off in response to time or events.
10. Which of the following system is driven by the time changes in the system?
a) Dynamic Control
b) Logic Control
c) Modular Control
d) Sequence Control
View Answer
Explanation: The Control system which is driven by the time changes in the system is known as Sequence Control System. This system uses internal timing devices to determine when the changes are to be initiated in the system.
11. Which layer handles the process of transferring information?
a) Physical Layer
b) Data Link Layer
c) Transport Layer
d) Process Layer
View Answer
Explanation: The process of transferring information is handled by Data Link layer. It transfers information by sending blocks of data across the physical link. It is the second layer of OSI model of communication architecture.
