MITSUBISHI Q3MEM-4MBS-SET datasheet PDF

Twisted pair cable.
Single bus.
Controller network (control station / common station).
MELSECNET/H network module capable of composing large scale flexible network system.
The MELSECNET/H network system includes the PLC network of the control station and the communication between the stations and the remote I/O network in the remote station remote I/O station Q3MEM-4MBS-SET PDF.
Optical fiber loop system Q3MEM-4MBS-SET..... High speed communication of 10Mbps/25Mbps is realized.
The distance between stations, the length of the total cable length, strong anti-interference.
Coaxial bus system...... Using low cost coaxial cable, the network construction cost is lower than that of the optical fiber loop network.
Twisted pair bus system Q3MEM-4MBS-SET PDF. ..... Combined with high performance price ratio network module and twisted pair cable,
The construction cost of network system is very low.8 slots.
Requires 1 power modules.
Used to install the old section of the large A series PLC module.
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 Q3MEM-4MBS-SET PDF.
So, sometimes also known as the order control.
And sequential control is divided into manual, semi-automatic or automatic.
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.
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.
Instruction count.
Due to the adoption of centralized sampling.
Centralized output mode.
TThere exist input / output hysteresis phenomena, i Q3MEM-4MBS-SET datasheet. 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 Q3MEM-4MBS-SET datasheet.
Read only memory. Manufacturers use, content can not be changed, power does not disappear.
