Type of input: DC leakage.
Input points: 16 points.
Input voltage: 12/DC24.
Input current: 3/7.
Common common point: 16.
The instruction list programming language is a programming language similar to assembly language mnemonic,
As well as assembly language by the operation code and the number of operations.
In the case of the computer for the PLC handheld programmer compile user program.
At the same time, the programming language of the instruction list corresponds to the ladder diagram programming language,
In PLC programming software can be converted to each other. Figure 3 is the instruction sheet corresponding to the ladder diagram of figure 2PLC.
The characteristics of instruction table programming language is used to represent mnemonic operation function,
In the handheld programmer on the keyboard using the mnemonic representation, easy to operate, can be programmed in computer;
There is a one-to-one correspondence between the ladder diagram and the ladder diagram. Its characteristics are basically consistent with the ladder diagram language.
I/O slots: 5 slots.
Outline dimension: 325*130.
CPU basic board can be plugged into 1 power modules,
1 CPU components and a maximum of 2, 3, 5, or 8 single slot size special function components and I/O components are respectively inserted and arranged.
Expansion ports are arranged on both sides of the base plate,
For connecting the expansion board for A1SX40.
Up to 3 extension substrates. CPU:A2SHCPU PLC is the same
A1SX40
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 A1SX40.
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 A1SX40. Programmable controller and related equipment,
Should be easy to make the industrial control system to form a whole, easy to expand the principle design of its functions.
As can be seen from the above definition, PLC is a program to change the control function of the industrial control computer,
In addition to the completion of a wide variety of control functions, as well as with other computer communications networking features. SRAM+E2PROM memory card.
RAM capacity: 32KB.
E2PROM capacity: 32KB. AnS, QnAS bus connection, the reader to write program 2 channel connection.
Input status and input information input from the input interface,
CPU will be stored in the working data memory or in the input image register.
And then combine the data and the program with CPU.
The result is stored in the output image register or the working data memory,
And then output to the output interface, control the external drive.
The response time of PLC is the interval between the time of the change of the external output signal oof the PLC and the time of the change of the external output signal which is controlled by it,
Lag time, this is the time constant of the input circuit,
The time constant of the output circuit, the arrangement of the user statement and the usse of the instruction,
The cycle scan mode of PLC and the way of PLC to refresh the I/O and so on A1SX40 A1SX40.
This phenomenon is called the I/O delay time effect.
