There are many A6TB models to different types of matching with the I/O module.
The cable can be connected to the I/O module of 32 points or 64 points by using the terminal row of the wire in advance.
Using the module wiring and terminal is not only connected with the connector.
SI-200/250 fiber optic cable.
Double loop.
MELSECNET (II) (Master / local station).
How to choose MITSUBISHI PLC.
MITSUBISHI PLC options include the choice of MITSUBISHI PLC models, capacity, I/O module, power, etc..
MITSUBISHI PLC distribution I/O points and design MITSUBISHI PLC peripheral hardware circuit
Draw the I/O point of the PLC and the input / output device connection diagram or the corresponding table,
This part also can be carried out in second steps MITSUBISHI A6TB
A6TB
Design PLC peripheral hardware circuit.
Draw the electrical wiring diagram of the other parts of the system,
Including the main circuit and the control circuit does not enter the PLC, etc..
The electrical schematic diagram of the system composed of I/O PLC connection diagram and PLC peripheral electrical circuit diagram MITSUBISHI A6TB.
So far the system''s hardware electrical circuit has been determined. 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.
Modular: PLC is the basic components of a separate module MITSUBISHI A6TB.
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 A6TB MITSUBISHI.
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 A6TB MITSUBISHI.
It is through the output interface circuit to the internal digital circuit into a signal to make the load action or not action A6TB MITSUBISHI.
User program storage capacity: it is a measure of how much the user application can store the number of indicators A6TB.
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 MITSUBISHI A6TB. Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4.
