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 A273UHCPU-S3 Programming Manual A273UHCPU-S3
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 engineering and safety systems engineering to study the specific solutions and measures to the safety of human computer science and technology A273UHCPU-S3 Programming Manual.
It realizes the transformation between the internal form of information and the acceptable form of human being A273UHCPU-S3 Programming Manual. SI-200/250 fiber optic cable.
Double loop.
MELSECNET (II) (remote I/O station).
According to the control requirements of the system, using the appropriate design method to design MITSUBISHI PLC program.
Procedures to meet the requirements of system control as the main line,
Write one by one to achieve the control function or the sub task of the program,
Gradually improve the functions specified by the system.
MITSUBISHI PLC initialization procedure. After MITSUBISHI PLC on power, the general need to do some of the initial operation,
In order to start making necessary preparations, to avoid the wrong operation of the system.
The main contents of the initialization program are: to some data area, counter and so on,
Data needed to restore some of the data area,
Set or reset some relays,
For some initial state display, etc.. Program memory capacity: 8k.
Input / output points: maximum 256 points.
A scan cycle of PLC must pass tthrough three stages: input sampling, program execution and output refresh A273UHCPU-S3 Manual .
PLC in the input sampling phase: first of all, in order to scan the sequence of all existing input latches in the input terminal of the state or input data read,
And write it into the corresponding input status register,
Refresh the input, then close the input port, enter the program execution stage A273UHCPU-S3 Manual .
