Output points: 64 points.
Voltage: DC12/24V.
OFF leakage current: 0.1mA.
Output type: transistor output (type sink).
Response time: 2ms.
32 points / a common end.
40 pin connector.
With the surge absorber.
Each scanning process. Focus on the input signal sampling. Focus on the output signal to refresh MITSUBISHI I/O Module User's Manual.
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 A1SY81EP
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 MITSUBISHI I/O Module User's 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.
Centralized output mode.
There exist input / output hysteresis phenomena, i.e., the input / output response delay.
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 MITSUBISHI I/O Module User's Manual.
Different series of different models of PLC has different performance, applicable occasions also have different emphasis,
Price also has a greater difference A1SY81EP User's Manual. Therefore PLC selection,
Under the premise of meeting the control requirements,
Should consider the best performance to price ratio, a reasonable choice of PLC A1SY81EP User's Manual.
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 A1SY81EP User's Manual. A set of 5 (LOGO removable, man-machine interface provides one).
Applicable model: A956WGOT. I/O points: 512.
Processing speed: sec/ 0.2u step.
Memory capacity: 64K bytes.
Program capacity: 14K step.
With the rapid development of microprocessor, computer and digital communication technology,
Computer control has been extended to almost all industrial fields.
Modern society requires manufacturing to respond quickly to market demand,
Production of small quantities, multi varieties, multi specifications, low cost and high quality products,
In order to meet this requirement,
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.
PLC programming is a digital computing operation of the electronic system,
Designed for applications in industrial environments.
It uses programmable memory,
An instruction used to perform logical operations, sequeence 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 A1SY81EP Manual.
Programmable controlller 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 MITSUBISHI I/O Module User's Manual.
