This set of Flexible Manufacturing System Multiple Choice Questions & Answers (MCQs) focuses on “Industrial Control Requirements”.
1. Which is a controller that is able to respond to the process within the short time so that the performance of the process is not degraded?
a) Time driven Controller
b) State driven Controller
c) Event driven Controller
d) Real Time Controller
View Answer
Explanation: The controller which is able to respond to the process within the short time so that the performance of the process is not degraded is known as real time controller. They are designed to communicate and interact with the process.
2. What is the special feature of real time controllers?
a) Seasoning
b) Multitasking
c) Pointing
d) Driving
View Answer
Explanation: The special feature of real time controllers is multitasking. The real time controllers have the capability to respond to more than one task and can operate it effectively.
3. Which can be generated at regular time intervals ranging from low values to several minutes in real time control?
a) Operator related Actions
b) Spacing related Actions
c) Time initiated Actions
d) Interval related Actions
View Answer
Explanation: In a real time control, time initiated actions can be generated at regular time intervals ranging from low values to several minutes in real time control. Re computation of optical process parameter will be required at specific times.
4. Which is often triggered by abnormal operating conditions in a real time control?
a) Condition initiated Interrupt
b) Process initiated interrupt
a) Execution initiated interrupt
b) Operator initiated interrupt
View Answer
Explanation: In a real time control, Process initiated interrupts are often triggered by abnormal operating conditions. This urges the need for some correction should be taken accordingly.
5. Which of the following events are related to the computer system itself?
a) Operator initiated events
b) Signal initiated events
c) System and Program initiated events
d) Control initiated events
View Answer
Explanation: The events which are related to the computer system itself are known as system and program initiated events. These events are similar to that of the common engineering and business related applications.
6. Which of the following events involve entering new programs, editing existing programs and emergency stops?
a) Operator initiated events
b) Signal initiated events
c) System and Program initiated events
d) Control initiated events
View Answer
Explanation: The events which involve entering new programs, editing existing programs and emergency stops are known as operator initiated events. It should be done exclusively by the operator personnel in order to give inputs to the control system.
