Input points: 32 points.
Input voltage: AC100 ~ 120V.
Current: 6mA.
Response time: 30ms.
16 points / a common end.
50 point terminal station.
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 GT2708-STBA
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 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.
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. Input points: 16 points.
Rated input voltage: AC100 ~ 120V.
Common way: 16 point / public end.
Input / output occupied points: 16 points (I/O distribution: 16 points).
External wiring connection: 18 point terminal.
The input and output module is also called control module, which can output signal when there is control requirement,
Or provide a switch signal to the controlled device,
At the same time, the feedback signal of the equipment can be received to report to the host computer,
Is an important part of the fire alarm linkage system,
The input and output modules in the market can provide a pair of passive normally open / normally closed contacts,
For controlling the controlled equipment, the module of the part can be set by the parameters,
Set to active output, corresponding to the two input and output modules, multiple input and output modules, and so on.
