Can connect the transmitter units 2 units using radius of about 50 meters (outdoor 200 meters).
According to the control requirements of the system, using the appropriate design method to design MITSUBISHI PLC program.
Write one by one to achieve the control function or the sub task of the program,
Gradually improve the functions specified by the system.
MITSUBISHI PLC initialization procedure. After MITSUBISHI PLC on power, the general need to do some of the initial operation,
In order to start making necessary preparations, to avoid the wrong operation of the system.
The main contents of the initialization program are: to some data area, counter and so on,
For some initial state display, etc..
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 MITSUBISHI AD22-S1. Input and output points: 1024 points.
Input / output data points: 1024 points
AD22-S1
Program capacity: 14K.
Basic command processing speed (LD command) s:1.0.
Coaxial data communication line function.
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 AD22-S1. 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.
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 MITSUBISHI AD22-S1.
Modular: PLC is the basic components of a separate module.
Medium and large PLC used this way. Easy maintenance. Input points: 16 points.
Voltage: AC100 ~ 120V.
Current: 10mA.
Response time: 25ms.
16 points / a common end..
20 point terminal station.
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.
PLC selection with the development of PLC technology, more and more types of PLC products,
Function is becoming more and more perfect, and its application is more and more extensive.
Different series of different models of PLC has different performance, applicable occasions also have different emphasis,
Price also has a greater difference. Therefore PLC selection,
Under the premise of meeting the control requirements,
Should consider the best performance to price ratio, a reasonable choice of PLC.
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 AD22-S1.
The length of the scan cycle is determined by the three.
CPU the speed of executing instructions.
Time of instruction.
Instruction count.
Due to thhe adoption of centralized sampling AD22-S1.
Centralized output mode.
There exist input / output hysteresis phenomena, i.e., the input / output response delay.
