8 slots; requires 1 AnS series PLC power modules;
Used to install large AnS series PLC module.
Base plate of AnS series PLC.
QA1S series PLC 8 slot main substrate.
AnS series of modules can be installed. 5 slots.
Requires 1 power modules.
Used to install the old section of the large A series PLC module Q172HCPU-T Structured Text Manual Q172HCPU-T Programming Manual.
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 Q172HCPU-T
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 Q172HCPU-T Structured Text Manual Q172HCPU-T Programming Manual.
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 Q172HCPU-T Structured Text Manual Q172HCPU-T Programming Manual.
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 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 ssystem Q172HCPU-T Structured Text Manual Q172HCPU-T 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 Q172HCPU-T Structured Text Manual Q172HCPU-T 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.
