Input and output points: 1024 points.
Input / output data points: 8192 points.
Program capacity: 14K.
Basic command processing speed (LD command) s:0.20 A73CPU-S1 PDF.
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 A73CPU-S1
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 A73CPU-S1 PDF.
Input refresh process. 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 A73CPU-S1 PDF.
The contents of the component image register are changed with the change of tthe execution of the program A73CPU-S1 Manual.
The length of the scan cycle is determined by the three.
CPU the speed of executing instructions.
Time of instruction.
Instruction count.
Due to the adoption of centralized sampling MITSUBISHI Programming Manual .
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 MITSUBISHI Programming Manual . 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. Category: Master station.
Transfer speed: 125kbps/250kbps/500kbps/1Mbps MITSUBISHI Programming Manual .
Transmission line form: bus system.
Total distance: 125kbps:1000m/250kbps:800m/500kbps:480m/1Mbps:240m.
The maximum connection units: 32.
Total points: input + output <=2048 point.
MITSUBISHI PLC detecction, fault diagnosis and display and other procedures A73CPU-S1 Programming Manual .
These procedures are relatively independent, generally in the basic completion of the program design and then add.
MITSUBISHI PLC protection and chain procedures.
Protection aand chain is an indispensable part of the program, must be carefully considered A73CPU-S1 Manual.
It can avoid the control logic confusion caused by illegal operations.
