Private vs Public limited company: Difference between them with definition \u0026 comparison chart

The data handling, storage, processing power, and communication capabilities of some modern PLCs are approximately equivalent to desktop computers.

Desktop computer controllers have not been generally accepted in heavy industry because the desktop computers run on less stable operating systems than PLCs, and because the desktop computer hardware is typically not designed to the same levels of tolerance to temperature, humidity, vibration, and longevity as the processors used in PLCs.

Operating systems such as Windows do not lend themselves to deterministic logic execution, with the result that the controller may not always respond to changes of input status with the consistency in timing expected from PLCs.

Desktop logic applications find use in less critical situations, such as laboratory automation and use in small facilities where the application is less demanding and critical.

The most basic function of a programmable controller is to emulate the functions of electromechanical relays.

Discrete inputs are given a unique address, and a PLC instruction can test if the input state is on or off.

Just as a series of relay contacts perform a logical AND function, not allowing current to pass unless all the contacts are closed, so a series of "examine if on" instructions will energize its output storage bit if all the input bits are on.

Similarly, a parallel set of instructions will perform a logical OR. In an electromechanical relay wiring diagram, a group of contacts controlling one coil is called a "rung" of a "ladder diagram ", and this concept is also used to describe PLC logic.

Some models of PLC limit the number of series and parallel instructions in one "rung" of logic. The output of each rung sets or clears a storage bit, which may be associated with a physical output address or which may be an "internal coil" with no physical connection.

Such internal coils can be used, for example, as a common element in multiple separate rungs. Unlike physical relays, there is usually no limit to the number of times an input, output or internal coil can be referenced in a PLC program.

Some PLCs enforce a strict left-to-right, top-to-bottom execution order for evaluating the rung logic. This is different from electro-mechanical relay contacts, which, in a sufficiently complex circuit, may either pass current left-to-right or right-to-left, depending on the configuration of surrounding contacts.

The elimination of these "sneak paths" is either a bug or a feature, depending on programming style. More advanced instructions of the PLC may be implemented as functional blocks, which carry out some operation when enabled by a logical input and which produce outputs to signal, for example, completion or errors, while manipulating variables internally that may not correspond to discrete logic.

Many of these protocols are vendor specific. This allows separate parts of a complex process to have individual control while allowing the subsystems to co-ordinate over the communication link.

These communication links are also often used for HMI devices such as keypads or PC -type workstations. Formerly, some manufacturers offered dedicated communication modules as an add-on function where the processor had no network connection built-in.

PLCs may need to interact with people for the purpose of configuration, alarm reporting, or everyday control. A human-machine interface HMI is employed for this purpose.

A simple system may use buttons and lights to interact with the user. Text displays are available as well as graphical touch screens.

More complex systems use programming and monitoring software installed on a computer, with the PLC connected via a communication interface.

A PLC works in a program scan cycle, where it executes its program repeatedly. The simplest scan cycle consists of 3 steps:.

The program follows the sequence of instructions. It typically takes a time span of tens of milliseconds for the processor to evaluate all the instructions and update the status of all outputs.

As PLCs became more advanced, methods were developed to change the sequence of ladder execution, and subroutines were implemented.

Newer PLCs now [ as of? This means that IO is updated in the background and the logic reads and writes values as required during the logic scanning.

Precision timing modules, or counter modules for use with shaft encoders , are used where the scan time would be too long to reliably count pulses or detect the sense of rotation of an encoder.

This allows even a relatively slow PLC to still interpret the counted values to control a machine, as the accumulation of pulses is done by a dedicated module that is unaffected by the speed of program execution.

In his book from , E. Parr pointed out that even though most programmable controllers require physical keys and passwords, the lack of strict access control and version control systems, as well as an easy to understand programming language make it likely that unauthorized changes to programs will happen and remain unnoticed.

Prior to the discovery of the Stuxnet computer worm in June , security of PLCs received little attention. Modern programmable controllers generally contain a real-time operating systems, which can be vulnerable to exploits in similar way as desktop operating systems, like Microsoft Windows.

PLCs can also be attacked by gaining control of a computer they communicate with. In recent years "safety" PLCs have started to become popular, either as standalone models or as functionality and safety-rated hardware added to existing controller architectures Allen-Bradley Guardlogix, Siemens F-series etc.

These differ from conventional PLC types as being suitable for use in safety-critical applications for which PLCs have traditionally been supplemented with hard-wired safety relays.

For example, a safety PLC might be used to control access to a robot cell with trapped-key access , or perhaps to manage the shutdown response to an emergency stop on a conveyor production line.

Such PLCs typically have a restricted regular instruction set augmented with safety-specific instructions designed to interface with emergency stops, light screens, and so forth.

The flexibility that such systems offer has resulted in rapid growth of demand for these controllers.

PLCs are well adapted to a range of automation tasks. These are typically industrial processes in manufacturing where the cost of developing and maintaining the automation system is high relative to the total cost of the automation, and where changes to the system would be expected during its operational life.

PLCs contain input and output devices compatible with industrial pilot devices and controls; little electrical design is required, and the design problem centers on expressing the desired sequence of operations.

PLC applications are typically highly customized systems, so the cost of a packaged PLC is low compared to the cost of a specific custom-built controller design.

On the other hand, in the case of mass-produced goods, customized control systems are economical. This is due to the lower cost of the components, which can be optimally chosen instead of a "generic" solution, and where the non-recurring engineering charges are spread over thousands or millions of units.

Programmable controllers are widely used in motion, positioning, or torque control. Some manufacturers produce motion control units to be integrated with PLC so that G-code involving a CNC machine can be used to instruct machine movements.

For small machines with low or medium volume. Similar to traditional PLCs, but their small size allows developers to design them into custom printed circuit boards like a microcontroller, without computer programming knowledge, but with a language that is easy to use, modify and maintain.

For high volume or very simple fixed automation tasks, different techniques are used. For example, a cheap consumer dishwasher would be controlled by an electromechanical cam timer costing only a few dollars in production quantities.

Automotive applications are an example; millions of units are built each year, and very few end-users alter the programming of these controllers. However, some specialty vehicles such as transit buses economically use PLCs instead of custom-designed controls, because the volumes are low and the development cost would be uneconomical.

Very complex process control, such as used in the chemical industry, may require algorithms and performance beyond the capability of even high-performance PLCs.

Very high-speed or precision controls may also require customized solutions; for example, aircraft flight controls.

Single-board computers using semi-customized or fully proprietary hardware may be chosen for very demanding control applications where the high development and maintenance cost can be supported.

The rising popularity of single board computers has also had an influence on the development of PLCs. A PID loop could be used to control the temperature of a manufacturing process, for example.

Historically PLCs were usually configured with only a few analog control loops; where processes required hundreds or thousands of loops, a distributed control system DCS would instead be used.

In more recent years, [ when? These small devices are typically made in a common physical size and shape by several manufacturers and branded by the makers of larger PLCs to fill out their low-end product range.

Most of these have 8 to 12 discrete inputs, 4 to 8 discrete outputs, and up to 2 analog inputs. Most have a small plug for connecting via RS or RS to a personal computer so that programmers can use simple Windows applications for programming instead of being forced to use the tiny LCD and push-button set for this purpose.

It is issued with and mentioned in the certificate of incorporation. Opening of Bank Account : Lastly, the PLC so formed, has to compulsorily open a current account with any bank, by submitting the registration certificate and the other required documents.

Public limited companies have contributed a lot to economic growth and development in a country.

The different benefits of a PLC are explained one by one in detail below:. Though PLC is an excellent option for the entrepreneurs who lack capital for starting a business, it has certain drawbacks making it unsuitable for business aspirants.

Following are the limitations of the public limited companies:. A public limited company is usually established to generate capital from external sources, i.

But a PLC is more suitable only to the large organizations which have a comprehensive perspective and higher growth possibilities, rather than a small shop located next door.

Other Documents : Other than the documents mentioned, the following are some more relevant documents need to be submitted under particular conditions or otherwise:.

As we already know about the various requirements and essential documents for the registration of the company, let us move forward towards the procedure of incorporation under the following eight steps:.

Name Reservation : The company needs to get the company name approved under the Companies Act, , which is valid up to twenty days from the date of approval.

Digital Signature Certificate DSC of Director : Filing of the online application form for a public limited company requires signatures supported by the DSC of the directors and the shareholders.

DSC can be taken by submitting a DSC application attached with identity proof, address proof, photographs of the respective signatory. Approval of Other Authorities : The applicant should next take and furnish the approval from the respective department, appropriate authority, regulatory body or ministry of Central or State Government depending on the type of business and the work, to the ROC.

Certificate of Incorporation : A registration certificate, also known as a certificate of incorporation is issued by the ROC after inspecting the application and documents submitted.

The business can be now commenced under the norms of a public limited company. It is issued with and mentioned in the certificate of incorporation.

Opening of Bank Account : Lastly, the PLC so formed, has to compulsorily open a current account with any bank, by submitting the registration certificate and the other required documents.

Each allotted share must be paid up to at least one quarter of its nominal value together with the whole of any premium.

A company can increase its authorised share capital by passing an ordinary resolution unless its articles of association require a special or extraordinary resolution.

A copy of the resolution — and notice of the increase on Form — must reach Companies House within 15 days of being passed. No fee is payable to Companies House.

A company can decrease its authorised share capital by passing an ordinary resolution to cancel shares which have not been taken or agreed to be taken by any person.

Notice of the cancellation, on Form , must reach Companies House within one month. A company may have as many different types of shares as it wishes, all with different conditions attached to them.

Generally share types are divided into the following categories:. Any existing bearer shares had to be converted to registered shares before February , or face cancellation.

A PLC has access to capital markets and can offer its shares for sale to the public through a recognised stock exchange.

It can also issue advertisements offering any of its securities for sale to the public. In contrast, a private company may not offer to the public any shares in itself.

The following documents, together with the registration fee are sent to the Registrar of Companies:. The key difference with the paper process is that there is no Form 12 and requirement for a statutory declaration.

This significantly speeds the process and Companies House's record for an Electronic Company formation is 23 minutes. Because the electronic process requires compatible software that works with Companies House eFiling service, [5] companies are usually formed through a Company Formation Agent.

Every company must deliver an annual return to Companies House at least once every twelve months. It has 28 days from the date to which the return is made up to do this.

The elimination of these "sneak paths" is either a bug or a feature, depending on programming style. More advanced instructions of the PLC may be implemented as functional blocks, which carry out some operation when enabled by a logical input and which produce outputs to signal, for example, completion or errors, while manipulating variables internally that may not correspond to discrete logic.

Unlike regular PLCs that are usually modular and greatly expandable, the PLRs are usually not modular or expandable, but their price can be two orders of magnitude less than a PLC, and they still offer robust design and deterministic execution of the logics.

Unlike factory automation using high speed Ethernet , communications links to remote sites are often radio based and are less reliable.

To account for the reduced reliability, RTU will buffer messages or switch to alternate communications paths. When buffering messages, the RTU will timestamp each message so that a full history of site events can be reconstructed.
