MITSUBISHI PLC protection and chain procedures.
Protection and chain is an indispensable part of the program, must be carefully considered.
It can avoid the control logic confusion caused by illegal operations AX21EU PDF datasheet .
MITSUBISHI PLC initialization procedure. After MITSUBISHI PLC on power, the general need to do some of the initial operation,
In order to start making necessary preparations, to avoid the wrong operation of the system AX21EU
The main contents of the initialization program are: to some data area, counter and so on,
Data needed to restore some of the data area,
Set or reset some relays,
For some initial state display, etc AX21EU PDF datasheet . .
MITSUBISHI PLC program simulation debugging
The basic idea of program simulation debugging is,
In order to facilitate the form of simulation to generate the actual state of the scene,
Create the necessary environmental conditions for the operation of the program.
Depending on the way the field signals are generated,
The simulation debugging has two forms of hardware simulation and software simulation AX21EU PDF datasheet . Cable length: 20 meters.
PC to GOT long distance connection cable.
For connection between GOT and GOT. Cable length: 30 meters.
For QCPU and GOT (need A9GT-QCNB) connection.
For the connection between GOT and GOT MITSUBISHI AX21EU PDF catalog. Output type: transistor output, drain type.
Output points: 8 points.
OFF leakage current: 0.1mA.
Output protection function: No MITSUBISHI AX21EU PDF catalog.
Rated load voltage / current: DC12V/DC24V/0.5A.
External connection: 2 wire.
According to the external connection mode and the external equipment input and output specifications,
Choose from a rich product lineup.
Finger protection through the upper part of the terminal,
The human body will not be exposed to live parts,
Therefore, the terminal station type remote I/O module can be directly mounted to the machine tool MITSUBISHI AX21EU PDF catalog. Enter points: 64 points.
Voltage: DC12/24V.
Current: 3/7mA.
Response time: 10ms.
32 points / a common end.
Cathode common.
40 pin connector.
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 componeent image register are changed with the change of the execution of the program AX21EU datasheet.
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 AX21EU PDF datasheet .
Centralized output mode.
There exist input / output hysteresis phenomena, i.e., the input / output response delay.
