Input points: 32 points.
Voltage: DC12/24V.
Current: 4/10mA.
Response time: 10ms.
8 points / a common end.
Negative utility.
38 point terminal station.
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 A0J2HCPU Manual A0J2HCPU Programming Manual A0J2HCPU
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 A0J2HCPU Manual A0J2HCPU Programming Manual.
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 A0J2HCPU Manual A0J2HCPU 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. 2 channel analog output module.
As well as aanalog input modules, the A1S62DA analog output component is built into a microprocessor,
It can convert binary data into voltage or current signals,
Offset and gain are set and stored in a microprocessoor,
It also includes other features as follows:
2 output channels A0J2HCPU Manual A0J2HCPU Programming Manual A0J2HCPU Manual A0J2HCPU Programming Manual.
High resolution digital input, plus or minus 12000.
