8 channel analog input module.
This is a high density of 8 channel A/D components,
Can receive voltage and current input, with the installation of the inside of the cover plate switch,
The input type and range of each channel can be set up according to the application requirements:
12 bit resolution,
Automatic drift correction function,
0 AI61-S1.5msec/1 cchannel,
-10-0-10V or 0-20mA input. 8 slots.
To install the power supply.
For Q4AR power 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 AI61-S1.
So, sometimes also known as the order control.
And sequential control is divided into manual, semi-automatic or automatic AI61-S1.
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 MITSUBISHI AI61-S1.
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 AI61-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 the adoption of centralized sampling MITSUBISHI AI61-S1.
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.
Enter 16 points.
Voltage and current: 14mA DC24V.
Response time: 8ms.
16 point 1 public end, 20 point terminal.
Detailed analysis of the process and work characteristics of the controlled object,
To understand the coordination between the controlled object machine, electricity and liquid,
The control requirements of the controlled object for MITSUBISHI PLC control system are put forward,
Determine the control program, to develop a design task book.
How to determine the input / output device of MITSUBISHI plc.
Acccording to the control requirements of the system,
All input devices and output devices required for the determination of the system,
To determine the input / output device related to the MITSUBISHI PLC,
To determine the I/O PLC points AI61-S1.
