Positive / negative 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 A173UHCPU PDF.
Read only memory. Manufacturers use, content can not be changed, power does not disappear A173UHCPU
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 A173UHCPU PDF.
Different series of different models of PLC has different performance, applicable occasions also have different emphasis,
Price also has a greater difference. Therefore PLC sellection,
Under the premise of meeting the control requirements,
Should consider the best performance to price ratio, a reasonable choice of PLC A173UHCPU PDF A173UHCPU Manual .
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 MITSUBISHI Programming Manual.
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.
The length of the scan cycle is determined by the three.
CPU the speed of executing instructions MITSUBISHI Programming Manual.
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. Bus connection.
Program 2 channel connection.
MITSUBISHI PLC detection, fault diagnosis and displaay and other procedures MITSUBISHI Programming Manual A173UHCPU Programming Manual.
These procedures are relatively independent, generally in the basic completion of the program design and then add.
MITSUBISHI PLC protection and chain procedures.
Protection aand chain is an indispensable part of the program, must be carefully considered A173UHCPU Manual .
It can avoid the control logic confusion caused by illegal operations.
