Data communication line module (optical cable) Master / local station for A3VTS multiplex 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.
MITSUBISHI PLC protection and chain procedures AC10TB-E PDF.
Protection and chain is an indispensable part of the program, must be carefully considered
AC10TB-E
It can avoid the control logic confusion caused by illegal operations. Output type: transistor output, source.
Output points: 16 points.
OFF leakage current: 0.1mA.
Output protection function.
Rated load voltage / current: DC12V/DC24V/0.1A.
External connection: 1 wire.
According to the external connection mode and the external equipment input and output specifications,
Choose from a rich product lineup AC10TB-E PDF.
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. Input points: 32 points.
Input voltage: AC200 ~ 240V.
Current: 5mA AC10TB-E PDF.
Response time: 55ms.
16 points / a common end.
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 compponent image register are changed with the change of the execution of the program AC10TB-E 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 AC10TB-E datasheet.
Centralized output mode.
There exist input / output hysteresis phenomena, i.e., the input / output response delay.
