CC-Link peripheral device connection.
RS-422 + CC-Link. Input points: 32 points.
Voltage: DC5/12/24V.
Current: 2.5/5mA.
Response time: 3ms.
8 points / a common end.
Positive / negative sharing.
38 point terminal station.
Each scanning process. Focus on the input signal sampling. Focus on the output signal to refresh AnS Series LR AnS Series Lloyd's Register.
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 AnS Series
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 AnS Series LR AnS Series Lloyd's Register.
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.
Centralized output mode.
There exist input / output hysteresis phenomena, i.e., the input / output response delay.
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 AnS Series LR AnS Series Lloyd's Register.
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.
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. Cable length 1m; used in A6TE2-16SRN.10BASE-T.
Q mode.
MITSUBISHI PLC is the main product in the production of MITSUBISHI motor in Dalian.
It uses a kind of programmable memory for its internal storage procedures,
Execute logic operation, sequence control, timing, counting and arithmetic operations, user oriented instruction,
And throuugh digital or analog input / output control of various types of machinery or production process AnS Series LR AnS Series Lloyd's Register.
When the programmer input programinto the user program memory,
Then CPU according to the function of the sysstem (the system program memory to explain the compiler),
Translate the user program into PLC internally recognized by the user to compile the program AnS Series LR AnS Series Lloyd's Register.
