i use both of them ladder and function block and both of them is very easy
The Ladder logic is the best one because It's very easy and the same of electrical diagram
and for the programing by functional blocks or statement list or C++ or assambly all of them very hard and for big projects and for us all our projects sample and small for that Ladder logic is the best
according to me ladder diagram is easier it's very easy to do and easily understandable
The Ladder logic is best for simple application and for complex application Sequential Function Charts (SFC)
اكيد Ladder ايسر يمكن عشان اتعرضت ليها اكتر من ال function block
Ladder, FBD and CFC are easy to use and understand, but when you have calculations and comparisons it is better to use IL (instruction list) or ST (structured text) and also if you want to hide your know-how
Ladder Diagram ............................easier to learn
I Prefer Ladder It is easy for me
There are Three Progrmming Modes
Programming has many formats, The most used is 'List' This is a textual Programming system.
special abbrevations called mnemonics are used to identify the diffrent comands being accessed. This types of programming is usually associated the diffrent commands with hand held programming units. These can also be classified as "On line" programmers; for a program to be written, The programming Unit must be connected to the PC.
An alternative to Instruction fomat programming is the grphical system called 'LADDER' programming. This system uses graphical picture or icons to represent the commands (unlike the mnemonics used the instruction progrmming). Ladder Programming is typically used on portable, dedicated programming equipment. This equipment alows "off line" programming. Off line means that the programming equpment does not have to be connected to the PC. This Allows the programs to be written in the lexury of as office. Once the programme is complete, the PC to be used is connected to the computer & the program is transfered to the PC.
Then i use the Ladder logic... that's it..
The last programming softeware is called SFC (sequential Function Chart). In SFC the graphical used are representative of the logic flow through a task i.e Program merely constant of a flow diagram of a flow diagram of the desired responceses.
