The instruction list programming language is a programming language similar to assembly language mnemonic,
As well as assembly language by the operation code and the number of operations A3ACPUP21-S1 Fundamentals Manual A3ACPUP21-S1 Programming Manual.
In the case of the computer for the PLC handheld programmer compile user program.
At the same time, the programming language of the instruction list corresponds to the ladder diagram programming language,
In PLC programming software can be converted to each other. Figure 3 is the instruction sheet corresponding to the ladder diagram of figure 2PLC.
The characteristics of instruction table programming language is used to represent mnemonic operation function,
Easy to remember, easy to grasp;
In the handheld programmer on the keyboard using the mnemonic representation, easy to operate, can be programmed in computer;
There is a one-to-one correspondence between the ladder diagram and the ladder diagram A3ACPUP21-S1 Fundamentals Manual A3ACPUP21-S1 Programming Manual. Its characteristics are basically consistent with the ladder diagram language. I/O points: 512.
Processing speed: sec/ 0.2u step.
Memory capacity: 64K bytes.
Program capacity: 14K step.
PLC programming is a digital computing operation of the electronic system,
Designed for applications in industrial environments.
It uses programmable memory,
An instruction used to perform logical operations, sequence control, timing, counting and arithmetic operations in its internal storage,
And through the digital, analog input and output, control of various types of machinery or production process A3ACPUP21-S1 Fundamentals Manual A3ACPUP21-S1 Programming Manual.
Programmable controlller and related equipment,
Should be easy to make the industrial control system to form a whole, easy to expand the principle design of its functions A3ACPUP21-S1 Fundamentals Manual A3ACPUP21-S1 Programming Manual.
