MITSUBISHI A960GOT-EBA-EU Hardware Manual A960GOT-EBA-EU User's Manual

A3VTS with additional floor.
Switch volume control is designed to,
According to the current input combination of the switch quantity and the history of the input sequence,
So that PLC generates the corresponding switching output,
In order to make the system work in a certain order.
So, sometimes also known as the order control A960GOT-EBA-EU Hardware Manual A960GOT-EBA-EU User's Manual.
And sequential control is divided into manual, semi-automatic or automatic A960GOT-EBA-EU
And the control principle is decentralized, centralized and hybrid control three.
Each scanning process. Focus on the input signal sampling. Focus on the output signal to refresh.
Input refresh process. When the input port is closed,
Program in the implementation phase, the input end of a new state, the new state can not be read A960GOT-EBA-EU Hardware Manual A960GOT-EBA-EU User's Manual.
Only when the program is scanned, the new state is read.
A scan cycle is divided into the input sample, the program execution, the output refresh.
The contents of the component image register are changed with the change of the execution of the program.
The length of the scan cycle is determined by the three.
CPU the speed of executing instructions.
Time of instruction A960GOT-EBA-EU Hardware Manual A960GOT-EBA-EU User's Manual.
Instruction count.
Due to the adoption of centralized sampling.
Centralized output mode.
There exist input / output hysteresis phenomena, i.e., the input / output response delay.
System program memory for storing system program,
Including management procedures, monitoring procedures, as well as the user program to do the compiler to compile the process of interpretation.
Read only memory. Manufacturers use, content can not be changed, power does not disappear. MELSECNET/B.
Twisted pair bus. Using A6SIM-X64Y64 simulation I/O module in the system before the connection can be carried out to control the process of debugging.
The simulation unit consists of 16 blocks of 4 switches and 4 LED LEDs. Twisted pair cable.
Single bus.
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 generral need to do some of the initial operation,
In order to start making necessary preparations, to avoid the wrong operation of the system A960GOT-EBA-EU Hardware Manual A960GOT-EBA-EU User's Manual.
The main contents of the initialization program arre: 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 A960GOT-EBA-EU Hardware Manual A960GOT-EBA-EU User's Manual. .
