MITSUBISHI A171SHCPU Fundamentals Manual A171SHCPU Programming Manual

A1ST60 analog timer module has 8 analog timers.
Each timer can be set between 0.1-600S,
Its accuracy plus or minus 2%.
Dial setting on the timing constant panel of the timer,
With a small screwdriver can be easily adjusted. Output points: 16 points.
Voltage: DC12/24V.
OFF leakage current: 0.1mA.
Output type: transistor output (type sink) A171SHCPU Fundamentals Manual A171SHCPU Programming Manual.
Response time: 2ms A171SHCPU
8 points / a common end.
20 point terminal station.
With short circuit protection.
With the surge absorber.
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 A171SHCPU Fundamentals Manual A171SHCPU Programming Manual.
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.
The length of the scan cycle is determined by the three.
CPU the speed of executing instructions.
Time of instruction.
Instruction count A171SHCPU Fundamentals Manual A171SHCPU Programming Manual.
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.
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 perrformance to price ratio, a reasonable choice of PLC A171SHCPU Fundamentals Manual A171SHCPU Programming Manual.
System program memory for storing system program,
Including management procedures, monitoring procedures, as well as the user program tto do the compiler to compile the process of interpretation A171SHCPU Fundamentals Manual A171SHCPU Programming Manual.
Read only memory. Manufacturers use, content can not be changed, power does not disappear.
