How to choose MITSUBISHI PLC A975GOT-TBA-B PDF.
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 A975GOT-TBA-B
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 A975GOT-TBA-B PDF. .
The electrical schematic diagram of the system composed of I/O PLC connection diagram and PLC peripheral electrical circuit diagram.
So far the system''s hardware electrical circuit has been determined A975GOT-TBA-B PDF. QCPU (Q mode) bus connection.
1 joint.
Applicable model: A956WGOT. Axis of control: 1.
A1SD75 series components show the MITSUBISHI in the manufacture and design of CNC, frequency converter,
Integrated technical experience in servo system and PLC.
These components have a wealth of features that are sufficient to meet the highest requirements in the application of positioning control MITSUBISHI Operating Manual.
A1SD75M, SCC net compatible controller, SSC network is the MITSUBISHI servo system control network.
In this network, the MR-H-13, MR-J-B, and MR-J2 servo amplifiers can be connected to a controller via a network system,
The connection is replaced by a pulse sequence and a voltage signal MITSUBISHI Operating Manual. 26 point line conversion adapter 1 line type 16 input CC-Link unit installation special connection conversion adapterNSD servo system.
A73CPU (P21/R21) -S3 dedicated.
Relay output interface circuit of PLC
Working proccess: 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 MITSUBISHI Operating Manual A975GOT-TBA-B Manual.
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.
When the programmer input programinto the user program memory,
Then CPU according to the function of the system (the system program memory to explain the compiler),
Translate the user program into PLC internally recognized by the user to compile the program.
I/O points is an important indicator of PLC.
Reasonable selection of I/O points can not only satisfy the control requirements of the system,
And the total investment of the system is the lowest.
The input and output points and types of PLC should be determined accordinng to the analog quantity and switch quantity of the controlled object,
Generally an input / output element to take up an input / output point A975GOT-TBA-B Operating Manual.
Taking into account the future adjustment and expansion,
In general should be estimaated on the total number of points plus the amount of spare 20%~30% A975GOT-TBA-B Manual.
The following describes the centralized control system I/O points of the estimate.
