MITSUBISHI PLC detection, fault diagnosis and display and other procedures AJ71ME81 PDF.
These procedures are relatively independent, generally in the basic completion of the program design and then add AJ71ME81
MITSUBISHI PLC protection and chain procedures.
Protection and chain is an indispensable part of the program, must be carefully considered.
It can avoid the control logic confusion caused by illegal operations. Output type: relay output.
Output points: 8 points AJ71ME81 PDF.
OFF leakage current: -.
Output protection function: No.
Rated load voltage / current: DC24V/AC240V/2A.
External connection: 2 wire.
According to the external connection mode and the external equipment input and output specifications,
Choose from a rich product lineup.
Finger protection through the upper part of the terminal,
The human body will not be exposed to live parts,
Therefore, the terminal station type remote I/O module can be directly mounted to the machine tool AJ71ME81 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 (DC24V).
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.
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.
It is through the output interface circuit to the internal digital circuit into a signal to make the load action or not action.
User program storage capacity: it is a meaasure of how much the user application can store the number of indicators AJ71ME81 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 AJ71ME81 datasheet. Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4.
