SI/QSI/H-PCF/ wide range H-PCF fiber optic cable.
Double loop.
Remote I/O network (remote control 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 peripheral hardware circuit.
Including the main circuit and the control circuit does not enter the PLC, etc..
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.
RS-232 2 channel.
Transmission speed: 2 channel total is 115.2kbps.
Equipment layer / field bus CC-Link device layer is the PLC and other control devices and sensors and drive devices connected to the field network,
Network for the lowest layer of the whole network system.
Using CC-Link field bus connection, the number of wiring is greatly reduced,
Improve the maintainability of the system MITSUBISHI AJ72QLP25
AJ72QLP25
And, not just the amount of data ON/OFF and other switches,
Can also be connected to the ID system, bar code reader, inverter, man-machine interface and other intelligent devices,
From the completion of a variety of data communication, the management of the terminal production information can be realized,
On the centralized management of the state of the machine movement,
Make maintenance work efficiency also greatly improved MITSUBISHI AJ72QLP25.
Q series PLC in the use of CC-Link function better,
And easier to use. 2 channels.
Input: DC0 ~ 10V, DC4 ~ 20mA.
Output (resolution): 0 ~ 4000.
Transform speed: 15ms/2 channel.
20 point terminal station.
Input status and input information input from the input interface,
CPU will be stored in the working data memory or in the input image register MITSUBISHI AJ72QLP25.
And then combine the data and the program with CPU.
The result is stored in the output image register or the working data memory,
And then output to the output interface, control the external drive.
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.
The working process of the input interface circuit: when the switch is closed, the diode light,
The transistor is then guided to the internal circuit and input signal under the irradiation of the light.
When the switch is off, the diode does not emit light, and the transistor is not on the way. Internal circuit input signal.
It is through the input interface circuit to the external switch signal into PLC internal can accept the digitaal signal AJ72QLP25.
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 arithhmetic operations, user oriented instruction,
And through digital or analog input / output control of various types of machinery or production process AJ72QLP25.
