Input and output points: 512 points.
Input / output data points: 512 points.
Program capacity: 14K.
Basic command processing speed (LD command) s:0.20.
Optical data communication line function (GI cable).
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 A1S62LS datasheet A1S62LS
Modular: PLC is the basic components of a separate module.
Medium and large PLC used this way. Easy maintenance.
Each scanning process. Focus on the input signal sampling. Focus on the output signal to refresh.
Input refresh process A1S62LS datasheet. When the input port is closed,
Program in the implementation phase, the input end of a new state, the new state can not be read.
Only when the program is scanned, the new state is read.
A scan cycle is divided into the input sample, the program execution, the output refresh.
The contents of the component image register are changed with the change of the execution of the program.
The length of the scan cycle is determined by the three A1S62LS datasheet.
CPU the speed of executing instructions.
Time of instruction.
Instruction count.
Due to the adoption of centralized sampling.
Centralized output mode.
There exist input / output hysteresis phenomena, i.e., the input / output response delay.
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. Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4. I/O points: 1024.
Processing speed: 0.09 sec/ step.
Memory capacity: 256K bytes.
Program capacity: 30K 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 opeerations, 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 A1S62LS PDF datasheet.
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 A1S62LS PDF datasheet.
