File language: English
26 point with the connection transformation adapter 16 type 1 point input CC-Link unit to install the special connection transformation adapterInput and output points: 1024 points.
Input / output data points: 1024 points.
Program capacity: 14K.
Basic command processing speed (LD command) s:1.0.
Coaxial data communication line function A1SJCPU-S3 Dedicated Instructions Manual A1SJCPU-S3 Programming Manual A1SJCPU-S3
AnNCPU command processing time and ACPU compare to 10-20% high speed processing.
User program storage capacity: it is a measure of how much the user application can store the number of indicators.
Usually in words or K words as units. 16 bit binary number is a word,
Every 1024 words are 1K words. PLC to store instructions and data in words.
General logical operation instructions each account for 1 words A1SJCPU-S3 Dedicated Instructions Manual A1SJCPU-S3 Programming Manual. Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4.
Integral type: the PLC components are installed together or a few pieces of printed circuit board,
And together with the power supply installed in the casing to form a single overall called the host or the basic unit, small, ultra small PLC using this structure A1SJCPU-S3 Dedicated Instructions Manual A1SJCPU-S3 Programming Manual.
Modular: PLC is the basic components of a separate module.
Medium and large PLC used this way. Easy maintenance. A1SS91 is used to insert a fixed control program in front of the user program to monitor the specific Y output.
Monitoring is carried out only when the CPU is in a state of running or stopping, and the monitoring failure is monitored in the suspended state.
When using this module, you can output from the I/O bus error contact or output from the running contact or the general contact output,
DC5V check can also be performed.
The popularization and application of PLC programming has been developed rapidly in our country,
It has been widely used in all kinds of mechanical equipment and production process of electrical control devices,
All walks of life have emerged a large number of application of PLC transformation of the results of the equipment.
Understand the working principle of PLC, have the ability to design, debug and maintain the PLC control system,
Has become the basic requirements of modern industry for electrical technicians and engineering students.
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.
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-tto-one correspondence between the ladder diagram and the ladder diagram A1SJCPU-S3 Dedicated Instructions Manual A1SJCPU-S3 Programming Manual A1SJCPU-S3 Dedicated Instructions Manual A1SJCPU-S3 Programming Manual. Its characteristics are basically consistent with the ladder diagram language.
