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 Q00JCPU-SET Common Instructions Manual Q00JCPU-SET Programming Manual Q00JCPU-SET
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 Q00JCPU-SET Common Instructions Manual Q00JCPU-SET Programming 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 Q00JCPU-SET Common Instructions Manual Q00JCPU-SET Programming Manual.
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 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.Master station.
Support DB A20 AnyWire systemm Q00JCPU-SET Common Instructions Manual Q00JCPU-SET Programming Manual.
DB A20 AnyWire system uses a separate transmission mode,
Sensor networks to achieve high speed and high reliability.
The transmission distance of 50m/200m/1km/3km can be selectted Q00JCPU-SET Common Instructions Manual Q00JCPU-SET Programming Manual.
1 modules can be up to 512 points of the input, 512 points of output (standard setting).
Even branch wiring, but also to detect transmission lines.
