Functional block diagram language is a kind of PLC programming language, which is similar to digital logic circuit AC300VG datasheet PDF catalog AC300VG PDF datasheet.
The function module is used to represent the function of the module,
Different function modules have different functions AC300VG
Functional module figure programming language features: functional block diagram programming language is characterized by a functional module for the unit,
Analysis and understanding of the control scheme is simple and easy: function module is to use graphical form of expression,
Intuitive, for a digital logic circuit based on the design of the staff is very easy to master the programming;
Control system with complex scale and complex control logic,
Because the function module diagram can clearly express the function relation, the programming debugging time is greatly reduced AC300VG datasheet PDF catalog AC300VG PDF datasheet. Input and output points: 1024 points.
Input / output data points: 1024 points AC300VG datasheet PDF catalog AC300VG PDF datasheet.
Program capacity: 14K.
Optical data communication line function (GI cable).
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.
User program storage capacity: it is a measure of how much the user applicaation can store the number of indicators AC300VG datasheet PDF catalog AC300VG PDF datasheet.
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 llogical operation instructions each account for 1 words AC300VG datasheet PDF catalog AC300VG PDF datasheet. Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4.
