Input and output points: 512 points.
Input / output data points: 512 points.
Program capacity: 14K.
Basic command processing speed (LD command) s:0.20.
Optical data communication line function (GI cable).
Integral type: the PLC components are installed together or a few pieces of printed circuit board,
And together with the power supply installed in the casing to form a single overall called the host or the basic unit, small, ultra small PLC using this structure HC-SFS502G2 1/9
Modular: PLC is the basic components of a separate module.
Medium and large PLC used this way. Easy maintenance.
Each scanning process. Focus on the input signal sampling. Focus on the output signal to refresh HC-SFS502G2 1/9.
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 HC-SFS502G2 1/9.
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.
User program storage capacity: it is a measure of how much the user application can store the number of indicators.
Usually in words or K words as units. 16 bit binary number is a word,
Every 1024 words are 1K words. PLC to store instructions and data in words.
General logical operation instructions each account for 1 words. Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4. Series Name: F920GOT with buttons, with a series of effective functional modules.

Display device: LCD STN.
Resolution: 128 * 64.
Installation type: panel mounting.
The built-in communication port: RS-422 (1ch) /RS-232C (1ch).
Power supply voltage: DC24V.
The touch screen is the interface between people and machines in the field of information exchange and function contact or interact with each other,
Information exchange, functional contact or mutual influence, the hard contact and soft touch of a person and machine,
This interface includes not only the direct contact point, including long-distance information transmission aand control function space HC-SFS502G2 1/9.
The man-machine interface is the central link in the man-machine system,
Mainly from the safety engineering branch of the safety ergonomics to study and put forward the basis for the solution,
And over safety engineering equipment engineeriingg,
Safety management engineering and safety systems engineering to study the specific solutions and measures of the safety of human computer science HC-SFS502G2 1/9.
