Twisted pair cable.
Single bus.
Remote I/O 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 A1SJ71LP21 Manual A1SJ71LP21 Reference Manual A1SJ71LP21
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 wrong operation of the system.
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 A1SJ71LP21 Manual A1SJ71LP21 Reference Manual. . Output points: 8 points.
Output voltage and current: DC12/24V, 0.5A/1 point, 3.2A/1 common end.
Response time: 2ms.
8 point /1 a public side.
Output form: transistor output, leakage type.
26 point terminal station.
Number of stations: 1 stops.
Type remote I/O unit (twisted pair data connection) A1SJ71LP21 Manual A1SJ71LP21 Reference Manual.
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 off 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 A1SJ71LP21 Manual A1SJ71LP21 Reference 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 A1SJ71LP21 Manual A1SJ71LP21 Reference Manual.
