SI/QSI/H-PCF/ wide range H-PCF fiber optic cable.
Double loop.

How to choose MITSUBISHI PLC.
MITSUBISHI PLC options include the choice of MITSUBISHI PLC models, capacity, I/O module, power, etc..
MITSUBISHI PLC distribution I/O points and design MITSUBISHI PLC peripheral hardware circuit
Draw the I/O point of the PLC and the input / output device connection diagram or the corresponding table,
This part also can be carried out in second steps A1NCPUP21 User's Manual A1NCPUP21
Design PLC peripheral hardware circuit.
Draw the electrical wiring diagram of the other parts of the system,
Including the main circuit and the control circuit does not enter the PLC, etc A1NCPUP21 User's Manual. .
The electrical schematic diagram of the system composed of I/O PLC connection diagram and PLC peripheral electrical circuit diagram.
So far the system''s hardware electrical circuit has been determined. Cable length 0.6m; used in A6TE2-16SRN.Cable length: 30 meters.
PC to GOT long distance connection cable.
For connection between GOT and GOT. For A6TBXY36/A6TBXY54/A6TBX70E (common cathode; drain type) long 3m A1NCPUP21 User's Manual. 32 point connector for compressed flat cable (37 pin D-Sub connector).Output points: 64 points.
Voltage: DC12/24V.
OFF leakage current: 0.1mA.
Output type: transistor output (type sink).
Response time: 2ms.
32 points / a common end.
40 pin connector.
With the surge absorber (optocoupler diode).
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 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.
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 performance to price ratio, a reasonable choice of PLC A1NCPUP21 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 A1NCPUP21 Manual .
Read only memory. Manufacturers use, content can not be changed, power does not disappear.
