Some mechanical industries, such as machine tools, textile machinery, electronic equipment and other industries,
In the country has bbeen developed for decades of history, relatively speaking, is relatively mature industry, in the long run,
These industries also exist the needs of equipment upgrades AJ71C21-S1 AJ71C21-S1.
In this upgrading process, there will be some small, has been using relatively low-end products manufacturers are eliminated,
But there are also a lot of enterprises in the process of equipment renewal,
Re positioning the needs to find those that can meet their development plans,
Equipment suppliers to help them improve their productivity AJ71C21-S1. Input and output points: 1024 points.
Input / output data points: 1024 points.
Program capacity: 14K.
Optical data communication line function (GI cable).
Each scanning process. Focus on the input signal sampling MITSUBISHI AJ71C21-S1. 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 MITSUBISHI AJ71C21-S1.
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 MITSUBISHI AJ71C21-S1.
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.
RS-232:1 channel, RS-422:1 channel.
BASIC program mode (A3MCPU corresponding): BASIC console interface to use.
Sequential program mode (program controller CPU correspondence): non sequential computer connection interface and use.
How to choose MITSUBISHI PLC.
MITSUBISHI PLC options include the choice of MITSUBISHI PLC models, capacity, I/O module, power, etc..
MITSUBISHI PLC distribution I/O points and design MITSUBISHI PLC peripheral hardware circuit
Draw the I/O point of the PLC and the input / output device connection diagram or the corresponding table,
This part also can be carried out in second steps.
Design PLC peripheral hardware circuit.
Draw the electrical wiring diagram of the other parts of the system,
Including the main circuit and the control circuit does not enter the PLC, etc AJ71C21-S1..
The electrical schematic diagram of the system composed of I/O PLC connection diagram and PLC peripheral electrical circuit diagram.
So far the system''s hardware electrical circuit has been determined.
