RS-232 2 channel.
Transmission speed: 2 channel total is 115.2kbps.
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 A1SJ71UC24-R2 Manual A1SJ71UC24-R2 User's Manual A1SJ71UC24-R2
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 A1SJ71UC24-R2 Manual A1SJ71UC24-R2 User's Manual.
Q series PLC in the use of CC-Link function better,
And easier to use. Input points: 32 points.
Voltage: AC100 ~ 120V.
Current: 12mA.
Response time: 25ms.
32 points / a common end.
38 point terminal station.
CE certification.
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 A1SJ71UC24-R2 Manual A1SJ71UC24-R2 User's Manual.
Read only memory. Manufacturers use, content can not be changed, power does not disappear.
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.
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.
Each scanning process. 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.
The contents of the component image register are changedd with the change of the execution of the program A1SJ71UC24-R2 Manual A1SJ71UC24-R2 User's 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 thhe adoption of centralized sampling A1SJ71UC24-R2 Manual A1SJ71UC24-R2 User's Manual.
Centralized output mode.
There exist input / output hysteresis phenomena, i.e., the input / output response delay.
