5 slots.
No need to install power.
For QnA/A series.
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.
And sequential control is divided into manual, semi-automatic or automatic NZ2AW1C2AL
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, 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. "Input points: 16 points.
Rated input voltage and frequency: DC24V.
Rated input current: TYP 7.0mA.
Response time: 0.1 ~ 70ms.
Common way: 16 point / public end.
Interrupt function: have.
External wiring connection mode: 18 point screw terminal.
The input and output module is the interface between the switch, sensor, actuator, and other control system of the ON/OFF signal processing.
Compared with the previous series, iQ-R MELSEC series of input and output modules have more features,
1 modules can be used for a variety of purposes, to help reduce the cost of deployment and maintenance costs.
The module design of the pursuit of convenience".
Paste the white label on the input module and paste the red label on the output module,
The rated specifications are clearly marked on the front of the module, which can prevent the use of errors.
The input and output number stamped on the top of the front display input and output module LED, can easily confirm the status of the ON/OFF.
The terminal arrangement of each signal is recorded on the wiring terminal of the 16 point module, and the false wiring can be prevented.
The 64 point module can be 32 points as the unit, through the switch to switch to display the input and output number.
In addition, serial number tag in the front of the module, can be easily recognized. "
