MITSUBISHI PLC program simulation debugging
The basic idea of program simulation debugging is,
In order to facilitate the form of simulation to generate the actual state of the scene,
Create the necessary environmental conditions for the operation of the program.
Depending on the way the field signals are generated,
The simulation debugging has two forms of hardware simulation and software simulation A32B. Cable length: 30 meters.
For QnA/A/FX (FX1, FX2, FX2C) CPU and GOT connection between.
For connection between FA-CNV_CBL and GOT A32B.
For connection between FX-2PIF and GOT.
For connection between FX-422AW0 and GOT.
For serial communication module AJ71QC24 (N) -R4 and GOT connection between.
For connection between AJ65BT-G4-S3 and GOT.
2 slots.
Can be installed in the power supply unit for A series units installed QnA/ A32B.

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 MITSUBISHI A32B.
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 MITSUBISHI A32B.
It is through the output interface circuit to the internal digital circuit into a signal to make the load action or not action.
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 MITSUBISHI A32B.
The input and output points and types of PLC should be determined according to the analog quantity and switch quantity of the controlled object,
Generally an input / output element to take up an input / output point.
Taking into account the future adjustment and expansion,
In general should be estimated on the total number of points plus the amount of spare 20%~30%.
The following describes the centralized control system I/O points of the estimate. QnA/ACPU bus connection.

Man machine interface is the interface between man and machine in the field of information exchange and function contact or influence,
Information exchange, functional contact or mutual influence, the hard contact and soft touch of a person and machine,
This interface includes not only the direct contact point line side,
It also includes the function of remote information transmission and control.
The man-machine interface is the central link in the man-machine system,
Mainly from the safety engineering branch of the safety ergonomics to study and put forward the basis for the solution,
And over the safety engineering equipment engineering, safety management engineerinng and safety systems engineering to study the specific solutions and measures to the safety of human computer science and technology A32B.
It realizes the transformation between the internal form of information and the acceptable form of human being.
