AJ71AR21 In order to start making necessary preparations, to avoid the wrong operation of the system MITSUBISHI AJ71AR21

Input type: DC input, positive public end / negative public end.
Input points: 16 points.
Enter the response time: 1.5ms the following.
Rated input voltage / current: DC24V/5mA.
Output form: transistor output, leakage type.
Output points: 16 points.
OFF leakage current: 0 AJ71AR21.1mA.
Output protection function.
Rated load voltage / curreent: DC12V/DC24V/0.1A.
External connection: 1 line /1 line type.
40 pin connector type (FCN connector type).
Through the 40 pin connector type (FCN connector type) can be connected to a variety of devices AJ71AR21.
Can be installed along the 6 direction.
Hardware simulation method is to use a number of hardware equipment to simulate the generation of the signal,
The signals are connected to the input end of the PLC system in a hard wired way, and the timeliness is strong AJ71AR21.
Software simulation method is in the MITSUBISHI PLC in the preparation of a set of simulation program,
The simulation provides the field signal, which is simple and easy to operate, but it is not easy to guarantee the timeliness.
Simulation of the process of debugging, debugging method can be used to segment, and the monitoring function of programmer MITSUBISHI AJ71AR21. Output points: 8 points.
Output voltage and current: DC24V/AC240V, 2A/1 point, 5A/1 common end.
Response time: 12ms.
8 point /1 a public side.
26 point terminal station MITSUBISHI AJ71AR21.
Number of stations: 1 stops.
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 AJ71AR21.
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.
3C-2V/5C-2V coaxial cable.
Double circuit.
MELSECNET (II) (Master / local station).
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 AJ71AR21.
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..
