AJ71C21 Terminal interface module MITSUBISHI AJ71C21

CC-link remote device station.
CC-link/LT master function.
Consumption current: 75mA (DC24V, power supply through the power adapter)
Current at startup: 165mA (DC24V, power supply through the power adapter)
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 AJ71C21..<
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 AJ71C21 AJ71C21.,
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 MITSUBISHI AJ71C21.
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. Input and output points: 512 points MITSUBISHI AJ71C21.
Input / output data points: 512 points.
Program capacity: 14K.
Basic command processing speed (LD command) s:1.0.
Coaxial data communication line function.
It is possible for AnNCPU to use ACPU as a sequential program.
The order of the ACPU program is to the following command;
In addition to a special broadcast on that can be used with AnNCPU MITSUBISHI AJ71C21.
User program storage capacity: it is a measure of how much the user application can store the number of indicators.
Usually in words or K words as units. 16 bit binary number is a word,
Every 1024 words are 1K words. PLC to store instructions and data in words.
General logical operation instructions each account for 1 words. Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4.
Integral type: the PLC components are installed together or a few pieces of printed circuit board,
And together with the power supply installed in the casing to form a single overall called the host or the basic unit, small, ultra small PLC using this structure.
Modular: PLC is the basic components of a separate module.
Medium and large PLC used this way. Easy maintenance.
RS-232:1 channel, RS-422:1 channel.
BASIC program mode (A3MCPU corresponding): BASIC console interface to use.
Sequential program mode (program controller CPU correspondence): non sequential computer connection interface and use.
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.
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 AJ71C21..
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.
