Brand:
MITSUBISHI
Name: floor
Model: A37RHB
7 slots.
Power supply unit.
Q4AR power supply duplex.
Switch volume control is designed to,
According to the current input combination of the switch quantity and the history of the input sequence,
So that PLC generates the corresponding switching output,
In order to make the system work in a certain order.
So, sometimes also known as the order control.
And sequential control is divided into manual, semi-automatic or automatic.
And the control principle is decentralized, centralized and hybrid control three.
Each scanning process. Focus on the input signal sampling. Focus on the output signal to refresh.
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.
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.
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.
System program memory for storing system program,
Including management procedures, monitoring procedures, as well as the user program to do the compiler to compile the process of interpretation.
Read only memory. Manufacturers use, content can not be changed, power does not disappear.
Self service (IN, OUT): SI optical cable.
Other aspects (IN, OUT): SI optical cable.
Data link anomaly Bureau bypass.
Inter agency extension.
Cable transformation. Input and output points: 1024 points.
Input / output data points: 1024 points.
Program capacity: 14K.
Basic command processing speed (LD command) s:1 A37RHB MITSUBISHI. 0.
Coaxial data communication line function.
AnNCPU command processing time and ACPU compare to 10-20% high speed processing A37RHB
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 A37RHB MITSUBISHI.
General logical operation instructions each account for 1 words. 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 A37RHB MITSUBISHI.
Modular: PLC is the basic components of a separate module.
Medium and large PLC used this way. Easy maintenance. There are many A6TB models to different types of matching with the I/O module.
The cable can be connected to the I/O module of 32 points or 64 points by using the terminal row of the wire in advance.
These cables have a variety of lengths to be selected, so that
Using the module wiring and terminal is not only connected with the connector. Category: slave station.
Transfer speed: 125kbps/250kbps/500kbps/1Mbps.
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.
MITSUBISHII PLC detection, fault diagnosis and display and other procedures A37RHB.
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 A37RHB.
It can avoid the control logic confusion caused by illegal operations.
