Output points: 64 points.
Voltage: DC5/12V.
Output type: Sink type.
Response time: 1ms.
32 points / a common end.
40 pin connector.
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 A273UHCPU Dedicated Instructions A273UHCPU
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.
The length of the scan cycle is determined by the three.
CPU the speed of executing instructions A273UHCPU Dedicated 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 A273UHCPU Dedicated Instructions.
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. CPU:A2SHCPU PLC is the same.
PLC program capacity: 30K step.
I/O points: 1024 points.
Processing speed (sequential order): 0.25 s/ step.
Control axis: up to 8.
Servo program capacity: 13K step.
Servo amplifier: SSCNET connected external servo amplifier.
PLC programming has a wide range of applications, powerful, easy to use, has become one of the main devices of modern industrial automation,
In all areas of industrial production has been widely used,
Applications in other areas (such as civil and home automation) have also been rapidly developed.
It uses programmable memory,
An instruction used to perform logical operations, sequence control, timing, counting and arithmetic operations in its internal storage,
And through digital, analog input and output,
Control of various types of machinery or production processes. Programmable controller and related equipment,
Should be easy too make the industrial control system to form a whole, easy to expand the principle design of its functions A273UHCPU Programming Manual.
As can be seen from the above definition, PLC is a program to change the control function of the industrial conttrol computer,
In addition to the completion of a wide variety of control functions, as well as with other computer communications networking features A273UHCPU Programming Manual.
