If you have basic knowledge in relays and what PLC is made of and how it works, it is much easier to understand the programming language that is used for it. But even without this information, these programming languages are easy to learn, it just takes practice to adapt to as many situations as possible.
Because PLCs are basically computers, the programming languages work the same as for the computer. The IT technicians are most likely to learn this, but like every language it is manageable. Online PLC Support is there always to help you out if you are stuck because there will always be situations where there is a better way to do it then you know.
There are several number systems made use of in the human interface to programmable logic controllers. At the fundamental level, at the actual computer electronic level, everything in any computer is binary. It is a base 2 number system, 2 states 0 and 1. Therefore, decimal, hexadecimal, octal and binary coded decimal are used to interpret the binary values present in the memory of the programmable logic controller and display them on the screen in the programming software whereas they are always binary in the PLC on the graphical user interface like rslogix 500, or any programming software, you may see a decimal value, hexadecimal, but they are representing binary numbers.
The binary numbers system is second nature to us, so we will use it as a springboard into binary. To have more information, look at the decimal system where you have indexing, exponential, and positional notation. Indexing would be like an odometer. Numbers at indexing are placed from 0 to 9 in various vertical positions, so if you take the least significant digit, which would be the zero on …Read more
