Introduction
Industrial Computer
PLC
programming language, which expresses a program as a series of “coils” and “contacts”, simulating the operation of electromechanical relays. The resultant program is the equivalent of an equation, which is executed continuously in a combinatorial manner.
What is ladder diagram
In this setting . . if the teacher pushes on with new concepts, the struggling students will fall farther behind
What is "Traditional Schools Practices?"
unit is the small collection of hard ware in the system that can do closed loop control. Local control unit interfaces directly to the process.
What Is Lcu?
any action which can reduce human efforts.
What is Automation?
PLC plays most important role in automation. All the monitoring as well as the control actions are taken by PLCs. PLC Senses the input through I/P modules, Processes the logic through CPU and memory and gives output through output module.
Role of PLC in Automation
Electronic plug in units used for interfacing the i/p and o/p device in the machine or process to be controlled.
What is role of I/O modules?
Perceived as achievable by those who set them.
What are "Attainable Goals?"
DCS is used for interfacing and computing functions and also provides the means of communication between the other devices. It consists of local control unit, low level interface, high level interface, shared communication facility
What Is The Significance Of Dcs?
The process of using special software tools or scripts to perform testing tasks such as entering data, executing the test steps and comparing the results
What is Automation testing?
In non modular PLCs the processor will have inbuilt power supply and I/Os in one unit. The modular PLC, will have separate slots for components like Power supply, I/O modules. You can select the I/Os or power supply as per the need.
Difference Between Fixed and Modular PLCs ?
PLC follows the following path
Scan cycle of PLC?
Learning that uses the same instrument or a common process utilizing the same criteria for determining the quality of student work.
What is a "Common Assessment?"
The Package based on a client server architecture consisting of servers and viewers. Servers are responsible for the collection and distribution of data. Viewers connect into servers and have full access to the collected data for viewing and control actions.
What Is Cimplicity?
Its a set of the structure of the entire automation suite. It is also a guideline, which if followed can result in a structure which is easy to maintain and enhance.
What is a framework?
Time required to read the I/P, Process the logic and update the output in one cycle.
What is meaning of scan time in PLC?
The system uses multiple processors, has a central database and the functionality is distributed.
The system has processor & I/O’s and some functional units like basic modules, communication modules and so on
Difference between PLC & DCS ?
sharing diverse ideas and making compromises so that all people are satisfied with the direction in which the school is moving.
What is "Top-down and Bottom-up Process?"
Industrial process: chemical plants, power generation and distribution, Metallurgy etc and nuclear process: reactors, nuclear waste etc
Application Areas Of Scada?
Open source tool like Selenium, JMeter etc.
Paid tools like QTP, Load Runner, Ranorex, RFT, and Rational Robot.
different types of an automation tool that you are aware of?
The capacity to switch from primary equipment to standby equipment automatically without affecting the process under control.
What is redundancy in PLC?
Difference between PLC & Relay ?
Data that represents facts or figures that, standing along, will not inform practice or lead to informed decisions versus data that is transformed putting data in context, and typially requires a basis for comparison.
What is "Data versus Information?"
The computerised hardware and software based project that provides a single integrated view of all control and information resources, enable engineers, supervisors, operators to view and interact with the working of an entire operation through graphical representation of their product process.
SCADA
Test Assertion Tool
Data Setup
Reporting tool
logging tool
Continous Integration tool
What are the important modules of an automation testing framework?
