Program memory capacity: 8k.
Input / output points: maximum 256 points.
With base plate and power supply.
PLC is the use of " sequential scanning, and constantly circulating " way to work.
That is, in the operation of CPU, PLC according to the user according to the control requirements of the coexistence of the user in the memory of the program,
According to the instruction sequence number (or address number) for periodic cyclic scan, such as no jump instruction,
From the first instruction to the user program execution sequence one by one, until the end of the program,
And then return to the first command, start the next round of the new scan, in the process of each scan,
Also complete the sampling of the input signal and the output status of the refresh and other work.
With the rapid development of microprocessor, computer and digital communication technology,
Computer control has been extended to almost all industrial fields.
Production of small quantities, multi varieties, multi specifications, low cost and high quality products,
Production equipment and automatic production line control system must have high reliability and flexibility,
PLC programming is to comply with the requirements of the emergence of it is based on a microprocessor based general industrial control device.
Designed for applications in industrial environments.
An instruction used to perform logical operations, 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.
Should be easy to make the industrial control system to form a whole, easy to expand the principle design of its functions.
Type of input: DC leakage.
Input points: 32 points.
Input voltage: DC12/24.

PLC is introduced by the relay control technology after the development of micro processing technology,
Can be easily and reliably used for switching control MITSUBISHI A1SJCPU-S3.
As the analog quantity can be converted into digital quantity, the number of digital quantity is just a number of switching value,
Therefore, after the conversion of analog, PLC can also be reliable for processing control
A1SJCPU-S3
Because the continuous production process often has the analog quantity, the analog quantity control is sometimes called process control MITSUBISHI A1SJCPU-S3.
Analog quantity is not electricity, and PLC can only handle digital quantity, quantity of electricity.
All to realize the conversion between them to have the sensor, the analog quantity into a number of power.
If this power is not standard, but also through the transmitter,
The non-standard power into a standard electrical signal, such as 1-5V, 4-20mA, 0-10V, etc..
At the same time, there is also an analog input unit (A/D),
Transform these standard electrical signals into digital signals,
The analog output unit (D/A), in order to transform the digital quantity after PLC processing into analog quantity -- standard electric signal MITSUBISHI A1SJCPU-S3 MITSUBISHI CPU unit.
So the standard telecommunication number, the conversion between the number of operations to use a variety of computing.
This requires the resolution of the analog unit and the standard electrical signal MITSUBISHI CPU unit. Cable length: 0.7 meters
Extending cable to connect CPU main substrate and extended substrate,
According to the model can provide different cable length,
If you need to connect the AnN type expansion substrate is required,
Selection of A1SC05NB (A1SC07NB) cable MITSUBISHI CPU unit. CPU:A2SHCPU PLC is the same.
PLC program capacity: 30K step.
I/O points: 1024 points.
Processing speed (sequential order): 0.25 s/ step.
Control axis: up to 8.
Servo program capacity: 13K step.
Servo amplifier: SSCNET connected external servo amplifier.
PLC programming has a wide range of applications, powerful, easy to use, has become one of the main devices of modern industrial automation,
In all areas of industrial production has been widely used,
Applications in other areas (such as civil and home automation) have also been rapidly developed.
It uses programmable memory,
An instruction used to perform logical operations, sequence control, timing, counting and arithmetic operations in its internal storage,
And through digital, analog input and output,
Control of various types of machinery or production processes. Programmable controller 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 A1SJCPU-S3.
As can be seen from the above definition, PLC is a program to change the control function of the industrial conttrol computer,
In addition to the completion of a wide variety of control functions, as well as with other computer communications networking features MITSUBISHI A1SJCPU-S3.
