8 channels.
Input: DC-10 ~ 10V, DC4 ~ 20mA.
Output (resolution): -2000 ~ 2000.
Transform speed: 2.5ms/1 channel.
47 point terminal station.
Each channel D can be set A/ transform the.
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 A2NCPU Common Instructions Manual A2NCPU Programming Manual .
And then combine the data and the program with CPU A2NCPU
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 A2NCPU Common Instructions Manual A2NCPU Programming Manual .
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 A2NCPU Common Instructions Manual A2NCPU Programming Manual .
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 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. DC input points: 16 points.
Input voltage and current: 3/7mA, DC12/24V.
Response time: 10ms.
Positive pole sharing.
16 point /1 a public side.
Bidirectional thyristor output points: 12 points.
Output voltage and current: AC100 ~ 240V, 0.6A/1 point, 2.4A/1 public end.
Response time: 0.5Hz1ms.
8 point /1 a public end, 4 point /1 a public end.
36 point terminal station.

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-maail 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 A2NCPU Common Instructions Manual A2NCPU Programming Manual .
At the same time, tthe use of the Internet FTP server functions and MELSEC protocol can be very easy to achieve the program upload / download and transfer of information A2NCPU Common Instructions Manual A2NCPU Programming Manual .
