CPU connection program input device.
ACPU use. Multi axis positioning controller.
Program capacity: Max 60K step.
Input / output points: 1920 points.
Control solenoid valve required I/O points by the action principle of the solenoid valve can be known,
A single coil solenoid valve with PLC control to 2 input and 1 output,
A double coil solenoid valve requires 3 inputs and 2 outputs,
A button needs an input; a light sensitive switch needs 4 or 2 inputs,
A signal lamp needs 1 output, band switch,
Several bands are required for several inputs,
In general, a variety of position switches are required to take up 2 input points A1S62RD3 PDF A1S62RD3 PDF A1S62RD3 Output points: 32 points.
Voltage: DC5/12/24V.
OFF leakage current: 0.1mA.
Output type: bidirectional thyristor output (type sink).
Response time: 10ms.
8 points / a common end.
50 point terminal station.
With the surge absorber.
Each scanning process. Focus on the input signal sampling A1S62RD3 PDF. 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 A1S62RD3 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 MITSUBISHI User's Manual.
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 MITSUBISHI User's 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 MITSUBISHI User's Manual.
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 controll requirements,
Should consider the best performance to price ratio, a reasonable choice of PLC A1S62RD3 User's 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 A1S62RD3 Manual .
Read only memory. Manufacturers use, content can not be changed, power does not disappear.
