MITSUBISHI A3VCPU Programming Manual (Common Instructions) PDF

Input and output points: 480 points.
Input / output data points: 480 points.
Program capacity: 8k.
Basic command processing speed (LD command) s:1.25.
RAM memory capacity: 32K, power supply A3VCPU PDF.
Modular: PLC is the basic components of a separate module.
Medium and large PLC used this way. Easy maintenance.
Relay output interface circuit of PLC
Working process: when the internal circuit output digital signal 1,
There is a current flowing through, the relay coil has a current, and then the normally open contact is closed,
Provide load current and voltage A3VCPU
When the internal circuit outputs a digital signal 0, there is no current flowing through it,
The relay coil does not have a current, and the normally open contact is broken off,
A current or voltage that is disconnected from the load A3VCPU PDF.
It is through the output interface circuit to the internal digital circuit into a signal to make the load action or not action A3VCPU PDF.
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 aas units A3VCPU Manual. 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 MITSUBISHI Programming Manual . Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4. Type of input: DC leakage.
Input points: 16 points.
Input voltage: 12/DC24.
Input current: 3/7.
Connection mode: terminal row
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 MITSUBISHI Programming Manual .
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 MITSUBISHI Programming Manual . 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,
Easy to remember, easy to grasp;
In the handheld programmer on the keyboard using the mnemonic representation, easy to operate, can be programmed in computer;
There is a one-tto-one correspondence between the ladder diagram and the ladder diagram A3VCPU Manual A3VCPU Programming Manual . Its characteristics are basically consistent with the ladder diagram language.
