Multimode fiber optic cable.
Double circuit.
Controller network (control station / common station).
Decentralized control of large scale controller,
IE CC-Link controller network module connected with various field network.
Effectively using Ethernet cable and connector on the market, can reduce the cost Q06HCPU Structured Text Manual Q06HCPU Programming Manual.
The performance of the cycle data update is improved Q06HCPU
The transmission delay time is shortened, and the synchronous waiting time of the application can be shortened.
On the same network to achieve the 256KB network shared memory (cycle data).
No need to distinguish the network can handle large capacity data.
QJ71GP21S-SX, CC-Link can be used as the control station of IE QJ71GP21-SX controller network, common station Q06HCPU Structured Text Manual Q06HCPU Programming Manual. SRAM+E2PROM memory card.
RAM capacity: 64KB.
E2PROM capacity: 64KB. 5 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 Q06HCPU Structured Text Manual Q06HCPU Programming Manual.
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.
There exist input / output hysteressis phenomena, i Q06HCPU Structured Text Manual Q06HCPU Programming Manual. 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 Q06HCPU Structured Text Manual Q06HCPU Programming Manual.
Read only memory. Manufacturers use, content can not be changed, power does not disappear.
