Output type: transistor source / drain type.
Output points: 8 points.
Load voltage: DC5/12/24/48.
Load current: 2A.
Connection mode: terminal row.
Common public end points: 1.
Switching value, also known as logic, refers to only two values, 0 or 1, ON or OFF.
It is the most common control, it is the advantage of PLC control,
Is also the most basic application of PLC MITSUBISHI AC30B-UL Manual.
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 AC30B-UL
So, sometimes also known as the order control.
And sequential control is divided into manual, semi-automatic or automatic MITSUBISHI AC30B-UL Manual.
And the control principle is decentralized, centralized and hybrid control three. Analog channel: 16 channels.
Input / output (resolution): 0 ~ 4000.
Conversion speed: 100ms/16 channel.
Analog module installation.
Power supply: AC85 ~ 132V.
According to the control requirements of the system, using the appropriate design method to design MITSUBISHI PLC program MITSUBISHI AC30B-UL Manual.
Procedures to meet the requirements of system control as the main line,
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 detection, fault diagnosis and display and other procedures.
These procedures are relatively independent, generally in the basic completion of the program design and then add.
Hardware simulation method is to use a number of hardware equipment to simulate the generation of the signal,
The signals are connected to the input end of the PLC system in a hard wired way, and the timeliness is strong.
Software simulation method is in the MITSUBISHI PLC in the preparation of a set of simulation program,
The simulation provides the field signal, which is simple and easy to operate, but it is not easy to guarantee the timeliness.
Simulation of the process of debugging, debugging method can be used to segment, and the monitoring function of programmer. Input points: 32 points.
Input voltage: DC12V/DC24V.
Current: 3/7mA.
Response time: 10ms.
16 points / a common end.
Positive pole sharing.
50 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 componennt image register are changed with the change of the execution of the program AC30B-UL 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 thhe adoption of centralized sampling AC30B-UL User's Manual.
Centralized output mode.
There exist input / output hysteresis phenomena, i.e., the input / output response delay.
