Request Report Methodology Programmable Logic Controller PLC technology is not recent in the industry, and is still in usage at a great extent by manufacturing companies. Programmable Logic Controller smoothens the mechanical automation process in manufacturing units and construction buildings.
November 8th, Explain and justify the factors that must be considered when choosing the size and type of PLC required for a given application i. Rick Densing November 8th, I have searched on this site and all that comes up are posters who continually moan at the original poster but yet fail to answer the question directky with any decent information Tom Jenkins November 8th, Logic Controllers Rick Densing November 8th, You might get some more help if you posted what you thought the answers were.
You would then get some feedback.
NitrogenY3K November 8th, I dont have the slightest clue what the answer is. I had a look at that pdf file and there wasnt much info on the types of plc, only a coupke of lines. They are attached to the machine being controlled.
The basic modules are the power supply, the main module containing the CPU, the input module and the output module. The main advantage is that the number of input and output terminals can be expanded to cope with changes to the hardware system.
Go back to basics and research this a bit more, use books! I will even recommend one for you.
Programmable Logic Controllers by W Bolton. See if your college library has a copy.
You might find it useful for the PLC module. Paul Steve Bailey November 8th, Yours is a question asked by nobody except the HNC proctors. Why would you check the internet first? Is there a text book for this class?
It should have an index. I believe the freestudy site offers an abundance of information especially for those taking the HNC courses. NitrogenY3K, get off your sorry backside and read Noone is going to hold your hand nor provide more than I already have.
Splitter (in Rack Mount) Modules for today’s high-port count applications that demand the best performance and the highest reliability under the most adverse of. Up to two modules can be mounted per CPU, allowing direct control of four motion axes. Using dedicated instructions, these axes can be controlled directly by the PLC . 3 plc units are unitary modular and rack mounted. i need to identify and describe the 3 type of programme logic controllet and explain their corresponding pratical application to the system, for example in a traffic light system.
Your attitude is just asking for more derision which IMHO you are highly deserving of. I regret wasting my time on you. The term modular is used for many systems AB describes the SLC as modular: It uses backplane and rack mounting so could be used as an example for "rack" http: This is a simplistic overview because the dividing lines between the types are decreasing DonsDaMan November 8th, Instead of having a single box with X number of inputs of type M and Y number of outputs of Type N, some engineer came up with the concept of putting the data and address bus in a single rack, similar to the way many "rack mounted," systems were operating at the time.
Marketing needed a way to show the world that this was the way to go. Of course, at another company, they had a fixed number of slots pre-determined in their rack, and called it "rack mounted," again taking its cue from marketing.
Then, around that time, someone was making up the curriculum for some standardized testing. They said, "Hey, the people should know the difference between these systems, since the salesmen think it is so important Lots of electronic devices like PLCs, computers, monitors, amplifiers, flux capacitors, and rheostatisticians were packaged so that they could be mounted in these racks.
As electronic equipment has gotten progressively smaller over the years, the 19" rack has fallen out of favor.
Today, the preferred standard is the DIN rail. There is some truth and a lot of fiction in the above.Modular PLC series. CQM1H. The original modular PLC system for versatile machine control Distributed control with the high-speed, high-capacity Controller Link network.
A Controller Link Unit can be mounted on the CQM1H CPU unit, and connected to . On the basis of product type, Programmable Logic Controls (PLC) market is segmented into Unitary PLCs, Modular PLCs, and Rack mount PLCs.
Unitary Programmable Logic Controls segment, due to its cost-effectiveness, small size, and less downtime; has been considered as the major PLC segment.
Rack mounted PLC's are the most practical of all three as they make the multi-adaptive features of the modular PLC's a lot more compact and able .
Modular PLC (Programmable Logic Controller) is preferred over fixed PLC owing to its capability to execute complex processes. Furthermore, modular PLCs are also called rack-mounted units, consisting of bases for installation of various I/O modules, which are easier to repair.
A Programmable Logic Controller, or PLC for short, is simply a special computer device used for industrial control systems. They are used in many industries such as oil refineries, manufacturing lines, conveyor systems and so on. A PLC (programmable logic controller) is the heart of an automated industrial system.
It executes control functions based on its internal program and data received from sensors.
