Input and output points: 1024 points.
Input / output data points: 1024 points.
Program capacity: 14K.
Basic command processing speed (LD command) s:0.20 A0J2HCPU-DC24 PDF.
Optical data communication line function (GI cable).
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 A0J2HCPU-DC24
Modular: PLC is the basic components of a separate module.
Medium and large PLC used this way. Easy maintenance.
Each scanning process A0J2HCPU-DC24 PDF. Focus on the input signal sampling. Focus on the output signal to refresh.
Input refresh process. When the input port is closed,
Program in the implementation phase, the input end of a new state, the new state can not be read.
Only when the program is scanned, the new state is read.
A scan cycle is divided into the input sample, the program execution, the output refresh A0J2HCPU-DC24 PDF.
The contents of the component image register are changed with the change of the execution of the program.
The length of the scan cycle is determined by the three.
CPU the speed of executing instructions.
Time of instruction MITSUBISHI Programming Manual.
Instruction count.
Due to the adoption of centralized sampling.
Centralized output mode.
There exist input / output hysteresis phenomena, i.e., the input / output response delay.
User program storage capacity: it is a measure of how much the user application can store the number of indicators MITSUBISHI Programming Manual.
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 MITSUBISHI Programming Manual. Output points: 8 points.
Output voltage and current: DC12/24V, 0.1A/1 point, 0.8A/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).
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-mmachine 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 A0J2HCPU-DC24 Manual .
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 mmodule 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 A0J2HCPU-DC24 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 A0J2HCPU-DC24 Manual .
