AJ71VP21 MITSUBISHI PLC detection, fault diagnosis and display and other procedures MITSUBISHI AJ71VP21 Multiple system module

Position detection axis number: 2 axis.
Resolution: 4096 * 32 ~ 409.6 * 320 rotation (multi turn).
Number of output channels: 16 channels.
When communicating in the PLC network of MITSUBISHI,
There is no sense of difference and discontinuity in the network,
Can carry on the remote monitoring, modification, debugging and other work of data communication and prograam,
Without taking into account the level and type of network AJ71VP21.
MELSECNET/H and CC-Link use the way of loop communication,
Periodically automatically send and receive messages,
Does not require specialized data communication procedures,
Simple parameters can be set AJ71VP21.
MELSECNET/H and CC-Link are used to transmit and receive the broadcast mode,
This can be done on the network data sharing.
For the use of Ethernet, MELSECNET/H, CC-Link network,
Can set the network parameters and various functions, simple and convenient in the Developer GX software screen AJ71VP21. 26 point line conversion adapter 1 line type 16 input CC-Link unit installation special connection conversion adapter
Data communication line module (optical cable) Master / local station for A3VTS multiplex system
MITSUBISHI PLC detection, fault diagnosis and display and other procedures MITSUBISHI AJ71VP21.
These procedures are relatively independent, generally in the basic completion of the program design and then add.
MITSUBISHI PLC protection and chain procedures MITSUBISHI AJ71VP21.
Protection and chain is an indispensable part of the program, must be carefully considered.
It can avoid the control logic confusion caused by illegal operations. 8 channels.
Input: DC-10 ~ 10V/DC4 ~ 20mA.
Output (resolution): -1000 ~ 1000, -2000 ~ 2000 MITSUBISHI AJ71VP21.
Transform speed: 2.5ms/1 channel.
47 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.
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 digital signal.
MITSUBISHI PLC is the main product in the production of MITSUBISHI motor in Dalian.
It uses a kind of programmable memory for its internall storage procedures,
Execute logic operation, sequence control, timing, counting and arithmetic operations, user oriented instruction,
And through digital or analog input / output control of various types of machinery or production process AJ71VP21.
