OFF leakage current: 0.1mA.
Output type: transistor output (type sink).
Response time: 2ms.
16 points / a common end.
38 point terminal station.
With the surge absorber.
Each scanning process. Focus on the input signal sampling. Focus on the output signal to refresh A73CPUP21-S1 Common Instructions Manual A73CPUP21-S1 Programming Manual .
Input refresh process A73CPUP21-S1 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.
The contents of the component image register are changed with the change of the execution of the program A73CPUP21-S1 Common Instructions Manual A73CPUP21-S1 Programming Manual .
The length of the scan cycle is determined by the three.
CPU the speed of executing instructions.
Time of instruction.
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.
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 A73CPUP21-S1 Common Instructions Manual A73CPUP21-S1 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.
System program memory for storing system program,
Including management procedures, monitoring procedures, as well as the user program to do the compiler to compile the process of interpretation.
Read only memory. Manufacturers use, content can not be changed, power does not disappear. A65B/A68B/A55B/A58B connection cable.
Length: 400mm. Output points: 24 points.
Output voltage and current: AC100 ~ 240V, 0.6A/1 point, 2.4A/1 public end.
Response time: 0.5Hz+1ms.
Output form: bidirectional thyristor output.
8 point /1 a public side.
36 point terminal station.
Number of stations: 4 stops.
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-mail receivingg and sending,
The user can send and receive the production information conveniently in any place of the world,
Build a remote monitoring management system A73CPUP21-S1 Common Instructions Manual A73CPUP21-S1 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 A73CPUP21-S1 Common Instructions Manual A73CPUP21-S1 Programming Manual .
