Input voltage range: AC100-120V/AC200-240V.
Output voltage: DC24V.
Output current: 1.2A additional power supply unit.
I/O points is an important indicator of PLC.
Reasonable selection of I/O points can not only satisfy the control requirements of the system,
And the total investment of the system is the lowest MITSUBISHI A2CCPU-DC24V.
The input and output points and types of PLC should be determined according to the analog quantity and switch quantity of the controlled object,
Generally an input / output element to take up an input / output point A2CCPU-DC24V
Taking into account the future adjustment and expansion,
In general should be estimated on the total number of points plus the amount of spare 20%~30%.
The following describes the centralized control system I/O points of the estimate MITSUBISHI A2CCPU-DC24V. Two slots in one side.
Power supply unit.
Q4AR duplex system.
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 MITSUBISHI A2CCPU-DC24V.
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 A2CCPU-DC24V MITSUBISHI. 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 A2CCPU-DC24V MITSUBISHI.
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 A2CCPU-DC24V MITSUBISHI.
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.
TThere exist input / output hysteresis phenomena, i A2CCPU-DC24V. e., the input / output response delay.
System program memory for storing system program,
Including management procedures, monitoring procedures, as well as the user program tto do the compiler to compile the process of interpretation MITSUBISHI A2CCPU-DC24V.
Read only memory. Manufacturers use, content can not be changed, power does not disappear.
