!how  are plc  programmed?

The answer to your question depends greatly upon the brand and model of PLC that you wish to learn to program. If the PLC in question is a currently-supported product, then find the manufacturer's website, and look for links to customer training. There is a standard for PLC programming, IEC 1131, but different brands can still be quite different. If you don't already have a good understanding of relay logic, then you should brush up on those skills before trying to learn PLC programming, as "ladder logic" is based on relay logic. Some PLC's are also programmed in Statement List logic and/or Flow Chart logic. Some programs may also use different languages in different sections of the program. You should get some good troubleshooting experience in your PLC programming class. Some manufacturers also offer "starter kits" at good prices for the go-getter who wants to learn on their own. A starter kit generally includes a small PLC, interface cable, and software.

Threw the books away years ago so dont have a pinout...If its the DB62 to DB15 cable Pacific Cable has it for $24.\nhttp://www.pacificcable.com/Allen-Bradley-Rockwell-Automation-Cables.html\n\nThat's an old plc...sorry for your luck.

Process control is usually done by programming the various regulatory elements (pumps, valves...). Much of this is done with symbolic objects which then receive alpha-numeric data for their operation levels.\n\nA basic understanding of programming is necessary if you are to configure a process.\n\nMore familiar desktop programming is required mainly for producers of process or analytical equipment, or for creating your own analytical programs which deal with measured data. Most laboratories will rely on standard equipment and desktop software to process their raw data and manage their final data in an information system. The better information systems have programmable interfaces for special problems, which is where good programming knowledge gives a clear advantage.

Run it through a compiler. That is what they do. Convert symbollic text (software code) into binary. The compiler you use all depends on the language you are programming in.\n\nFor example, for c/++, in linux you could use gcc/gpp to compile an application. It could then be ran standalone on other linux computers. Windows/Mac/all computers in the world work this way. Just FYI the most basic compiler is called an assembler, it takes symbollic assembly language (the most basic human readable computer code) and converts it directly to the hex equivelant, i.e. binary. Many high level languages like C convert to assembly before the final compilation into hex (binary).

Allen Bradley has PLC simulator software.  I believe it will simulate the usual SLC500 and micrologix line of PLCs.  As for a book, start at www.AB.com and check out their knowledge base.

it depends on what the board is going to do, and what micro you are using. for just the micro alone, you will need a power supply, a crystal (usually, some have an internal osc.), a reset circuit (as simple as a cap, and a resistor), and some sort of output for the ports on the micro, like LED's. if the micro is a DIP package, then an IC socket so you can remove it so you can program the code into it. \n\nyou also need software to write your code (in C or assembly), and a programmer to program it into the micro.

I am willing to bet (but am not completely sure) that the LED pulses, which can be interpreted digitally, to perform the different actions (how else would the TV "know" to adjust volume, channel, ect?). The universal remotes would simply have all those different coding systems preprogrammed into it (notice how you have to select one with a universal remote). You could probably figure it out for sure by probing the input trace to the LED with an oscilliscope and enter in various commands, but who has the time right?

An automated system for controlling acces to an area.  If you use a simple set of sensors, a PLC and a program that says how many people, machines or boxes should enter an area, and you wire that to an alarm or an automatic door, you can make sure that only the number you programmed on the PLC can enter a building, a storehouse, etc.  This kind of project is easy to build and it can be very useful in almost any kind of industry.

Verilog is a lot like C or Java, with some syntax differences. The real trick is learning how to apply the key areas of the language to a specific task, for example, synthesizable digital logic design or verification. Your best bet is always to learn by example, so that you can focus your energy on the subset of the language and syntax you'll need to get the job done.\n\nYou may be able to find resources on www.synopsys.com in terms of how to write synthesizable code. Also search the web and you'll find some freeware verilog simulators which will help you run your code. There are also some books available on amazon.com.

How to work it? It's not very difficult. You just need to write your code and compile it.\n\nUnfortunately I can't send you anything, but you can check out my first source for more information.
