AJ71ME81 ME-NET module Data needed to restore some of the data area, MITSUBISHI AJ71ME81

Output points: 32 points.
Voltage: DC12/24V.
OFF leakage current: 0.1mA.
Output type: transistor output (type sink).
Response time: 2ms.
38 point terminal station.
With the surge absorber.
The number of I/O thyristor DC motor control required tube DC motor speed control system is the main form of DC speed regulation,
The thyristor rectifieer unit is used to supply power to the DC motor AJ71ME81.
PLC control of the DC drive system, the input of the PLC in addition to the main signal outside the signal,
We need to consider the switching signal, the fault signal transmission device, brake signal and fan fault signal AJ71ME81.
The output of the PLC mainly consider the speed command signal positive 1~3 level, 1~3 level, allowing reverse switching signal and brake open signal etc AJ71ME81..
In general, a reversible DC drive system controlled by PLC is approximately 12 input points and 8 output points,
An irreversible DC drive system requires 9 inputs and 6 output points.
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 arithmetic operations, user oriented instruction,
And through digital or analog input / output control of various types of machinery or production process MITSUBISHI AJ71ME81.
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 MITSUBISHI AJ71ME81 MITSUBISHI AJ71ME81. Output points: 24 points.
Output voltage and current: DC24V/AC240V, 2A/1 point, 5A/1 common end.
Response time: 12ms.
8 point /1 a public side.
36 point terminal station.
Number of stations: 4 stops.
Compact remote I/O unit.
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.
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.
Q series PLC in the use of CC-Link function better,
And easier to use.
Mitsubishi Co PLC network inherited the traditional use of the MELSEC network,
And make it better in terms of performance, function, easy to use etc..
Provides a layer of three layers of clear network, to provide the most suitable network products for a variety of uses.
The information layer /Ethernet (Ethernet) information layer is the highest level of the network system,
Mainly in the PLC, the device controller and production management with PC transmission between production management information, quality management information and the operation of equipment, etc.,
Information layer using the most common Ethernet.
It is not only able to connect the PC system UNIX, windows system, etc.,
And can connect a variety of FA devices.
The Ethernet module has the function of Internet e-mail receiving and sending,
The user can send and receive the production information conveniently in any place of the world,
Build a remote monitoring management system.
At the same time, the use of the Internet FTP server functions and MELSEC protocol can be very easy to achieve the program upload / download and transfer of information.
ME-NET interface unit.
According to the control requirements of the system, using the appropriate design method to design MITSUBISHI PLC program.
Procedures to meet the requirements of system control as the main line,
Write one by one to achieve the control function or the sub task of the program,
Gradually improve the functions specified by the system.
MITSUBISHI PLC initialization procedure. After MITSUBISHI PLC on power, the general need to do some of the initial operation,
In order to start making necessary preparations, to avoid the wwrong operation of the system AJ71ME81.
The main contents of the initialization program are: to some data area, counter and so on,
Data needed to restore some of the data area,
Set or reset some relays,
For some initial state display, etc..
