8 slots.
The main substrate needs to be equipped with CPU and power supply.
Support for high speed communication between multi CPU.
Requires 1 power modules.
Used to install Q series modules.
A variety of modules with excellent performance,
Meet the needs of various control from analog to location.
Q series module products include a variety of types of I/O, analog and positioning function module Q00JCPU-S8 Programming Manual Q00JCPU-S8
Can fully meet the switch, sensor, such as the input and output, temperature, weight, flow and motor, drive control,
As well as the requirements of high-precision control of the positioning of the industry, the control needs of various fields.
Can also be used in combination with the CPU module to achieve appropriate control Q00JCPU-S8 Programming Manual. 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.
So, sometimes also known as the order control Q00JCPU-S8 Programming Manual.
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 mmode Q00JCPU-S8 Manual .
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 Q00JCPU-S8 Manual .
Read only memory. Manufacturers use, content can not be changed, power does not disappear.
