PLC in the input and output processing, analog control, position control, the need for many data registers to store data and parameters. The data register is 16 bits and the most significant bit is the sign bit. Two data registers can be used to store bit data, the most significant bit is still the sign bit. The data registers are of the following types: 1. According to the parameter setting, D or higher can be used as the file register. The function of the special data register is used to monitor the running status of the PLC.

In Fig. The same circuit can be drawn using ladder diagram. A ladder diagram consists of individual rungs.

Each rung must contain one or more inputs and one or more outputs.

The first instruction on a rung must always be an input instruction and last instruction on a rung should always be an output coil.

The ladder diagram of Fig. Hence, in Fig. Each symbol or instruction has been given an address. This address sets aside a certain storage area in the PLC data files so that the status of the instruction i. Most PLCs uses 16 slots or bit storage locations. In the example given above, two different storage locations or PLC Register are used. In the tables of two registers 00 and 05 shown in Fig. Register 05 shows that bit 00 corresponding to output was a logic 0.

The logic 0 or 1 indicate whether an instruction is False or True. Hence, in the above example, SW1 must be logic 1 and SW2 must be logic 0, then and only then the output coil will be True, that is energized. If any instruction on the rung before the output coil is false, then the output coil will be false not energized. September 23, Helping rescue centres in the UK.

These Registers are used for performing the various Operations. This register is used to access data and instructions from memory during the execution phase of an instruction. Suppose CPU wants to store some data in the memory or to read the data from the memory. It places the address of the-required memory location in the MAR. It keeps track of the the next memory address of the instruction that is to be executed once the execution of the current instruction is completed.

In other words, it holds the address of the memory location of the next instruction when the current instruction is executed by the microprocessor.

RAMor the data after a fetch from the computer storage. It acts like a buffer and holds anything that is copied from the memory ready for the processor to use it. MDR hold the information before it goes to the decoder. MDR which contains the data to be written into or readout of the addressed location. For example, to retrieve the contents of cellwe would load the value in binary, of course into the MAR and perform a fetch operation. When the operation is done, a copy of the contents of cell would be in the MDR.

When the operation is completed the contents of cell 4 will have been set to 98, by discarding whatever was there previously. The MDR is a two-way register. When data is fetched from memory and placed into the MDR, it is written to in one direction. When there is a write instruction, the data to be written is placed into the MDR from another CPU register, which then puts the data into memory.

The Memory Data Register is half of a minimal interface between a micro program and computer storage, the other half is a memory address register. Also known as base register. An index register in a computer's CPU is a processor register used for modifying operand addresses during the run of a program. This register holds the contents of data or instruction read from, or written in memory.

Dinesh authors the hugely popular Computer Notes blog.To start a company which you own, manage and develop yourself is a wide-spread ambition. There are many attractions if you register a company - independence, challenge and excitement; meeting new people and new situations; financial rewards if the business 'takes off'. Equally, though, an 'own' business means hard work, determination, new obligations and responsibilities.

Each new situation needs research, judgement, decision-making - then standing by the consequences and reaping the rewards when you look to start a company. Whether to register a company as a Limited or PLC Company, and how to go about it are questions which can be time-consuming and confusing.

The guide is user-friendly yet comprehensive and covers everything you should know about how to start a company as a PLC - including the pitfalls, which we will service will ensure you avoid. There is one highly significant difference between a limited company and a Public Limited Company PLC and that is status.

Having 'PLC' or 'plc' at the end when you register a company adds prestige, respect and credibility. Customers, staff and suppliers are more aware of plc status rather than just a simple limited name. Even by not being listed you can sell as many shares to the public or employees as you wish and thereby raise working capital for company use. Obviously if you sell more shares than your own shareholding you can find yourself outvoted or not in control so read the share sections carefully.

No-one can ever buy shares in your company without your consent so you can keep your plc as private as you wish, a husband and wife business can still have the prestige and cachet of a PLC. If a normal Limited company fails, the limit of liability an owner must pay is governed by how many shares he has, ie. However, if you have invested money or assets into the PLC, then your liability has been paid up and creditors cannot come to you for more.

Obviously, if you use your PLC company properly these scenarios should not arise. Some people trade through a limited company and have a PLC for status, which does not do risky trading.

A PLC can be formed when you start a company and remain dormant, so it does not even trade at all. A PLC is seen as having greater prestige and status. This may be partly an image, but it does affect the behaviour of clients, customers, suppliers - and employees.

The ownership of a company is known precisely, so it is easier to value, buy and sell.

The owners are listed along with the proportion of the Company or Shareholding that they own. Starting a company as a PLC is not expensive, usually a small sum compared with the total investment required to establish a new business, and the prestige you get will outweigh the cost. This is how suppliers check up on a Company before opening a line of credit. PLC status gives suppliers and customers greater confidence.

Company assets belong to the Company and must be used for Company business. Directors benefit in other ways and can receive dividends on which the company pays tax and there is no National Insurance payable on Dividends. There are many technical matters with regards to tax and National Insurance you need to consider when you start a company, so talk to your accountant before deciding what is the most advantageous way for you to take drawings.

To start a company, it has to be owned. It must have at least two owners. Owners are technically Members.

If bit 9 is set then it is acknowledged. If there is an alarm i would like to present this alarm with name and value in a list. The program should read through these registers continuously and always check the bits. Can someone show me an example of this?

Is it best to dedicate a own thread for this or what? Should i use windows forms or WPF? You can get the same output using a bit-mask.

PLC Basics

Write string. You could also put all the registers in to a single BitArray. But remember that the LSB is index 0. I would have a system timer do the read operation and report any connection errors.

This would load the register values in to properties to allow external access. It also means that should you need UI then the read process is not hindered by UI thread operations and vice versa.

I will try this.

So basically what you mean is that i should use different threads for reading and writing? Do you have any thoughts about writing a realtime alarm handling application?

I was thinking about using MySQL as database for the system where alarm texts, attributes and logging of each alarm will be stored. This is necessary to ensure the PLC connection is not shared between threads; otherwise you will have trouble with synchronisation. This thread should put the data in to some common shared resource. This could be a database or an object instance of a custom class written for this purpose.

What those tasks do is down to your application.
