Meet safety standards: EN954-1 class 4, 13849-1 PL e ISO.
Safe input points: 1 points (2 input).
Start input points: 1.
Input type: N type (positive public end / negative public end input)
Safe output points: 1 points (3 output).
Spring clip terminal.
Additional security system.
Simply connect to the existing CC-LINK, you can add an independent security features Q172CPUN-T PID Control Instructions Manual Q172CPUN-T Programming Manual Q172CPUN-T
Saving wiring by CC-link connection.
The wiring is not needed in particular to the condition monitoring of the safety relay module, and realizes the wiring of the cabinet and the other provinces.
Visualization of installation status.
Can monitor the safe output, as well as the safety input and the internal state of the relay, in the safety circuit to facilitate the identification of the reasons for the start Q172CPUN-T PID Control Instructions Manual Q172CPUN-T 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 Q172CPUN-T PID Control Instructions Manual Q172CPUN-T 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 hysteresis phenomena, ii Q172CPUN-T PID Control Instructions Manual Q172CPUN-T 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 Q172CPUN-T PID Control Instructions Manual Q172CPUN-T Programming Manual .
Read only memory. Manufacturers use, content can not be changed, power does not disappear.
