PLC is introduced by the relay control technology after the development of micro processing technology,
Can be easily and reliably used for switching control A3NCPU Programming Manual A3NCPU
As the analog quantity can be converted into digital quantity, the number of digital quantity is just a number of switching value,
Therefore, after the conversion of analog, PLC can also be reliable for processing control.
Because the continuous production process often has the analog quantity, the analog quantity control is sometimes called process control A3NCPU Programming Manual.
Analog quantity is not electricity, and PLC can only handle digital quantity, quantity of electricity.
All to realize the conversion between them to have the sensor, the analog quantity into a number of power.
If this power is not standard, but also through the transmitter,
The non-standard power into a standard electrical signal, such as 1-5V, 4-20mA, 0-10V, etc A3NCPU Programming Manual. .
At the same time, there is also an analog input unit (A/D),
Transform these standard electrical signals into digital signals,
The analog output unit (D/A), in order to transform the digital quantity after PLC processing into analog quantity -- standard electric signal MITSUBISHI A3NCPU Manual .
So the standard telecommunication number, the conversion between the number of operations to use a variety of computing MITSUBISHI A3NCPU Manual .
This requires the resolution of the analog unit and the standard electrical signal. Memory card interface, serial interface.
On-line debugging is the process that will through the simulation debugging to further carry on the on-line unification to adjust MITSUBISHI A3NCPU Manual .
On-line debugging process should be step by step,
From MITSUBISHI PLC only connected to the input device, and then connect the output device, and then connect to the actual load and so on and so on step by step.
If you do not meet the requirements, the hardware and procedures for adjustment.
Usually only need to modify the part of the program can be. SI-200/250 fiber optic cable.
Double loop.
MELSECNET (II) (Master / local station).
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.
Design PLC peripheraal hardware circuit A3NCPU Dedicated Instructions.
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..
The electrical schematic diagram of the system compoosed of I/O PLC connection diagram and PLC peripheral electrical circuit diagram A3NCPU Programming Manual.
So far the system''s hardware electrical circuit has been determined.
