PLC is the use of " sequential scanning, and constantly circulating " way to work.
That is, in the operation of CPU, PLC according to the user according to the control requirements of the coexistence of the user in the memory of the program,
According to the instruction sequence number (or address number) for periodic cyclic scan, such as no jump instruction,
From the first instruction to the user program execution sequence one by one, until the end of the program,
And then return to the first command, start the next round of the new scan, in the process of each scan,
Also complete the sampling of the input signal and the output status of the refresh and other work MITSUBISHI A1SJ71PB93D MITSUBISHI A1SJ71PB93D A1SJ71PB93D

Output points: 16 points.
Load voltage: DC12/24.
Load current: 0.8A.
Connection mode: terminal row.
Common public end points: 8.
Switching value, also known as logic, refers to only two values, 0 or 1, ON or OFF.
It is the most common control, it is the advantage of PLC control,
Is also the most basic application of PLC.
Switch volume control is designed to,
According to the current input commbination 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 A1SJ71PB93D.
So, sometimes also known as the order control.
And seqquential control is divided into manual, semi-automatic or automatic A1SJ71PB93D.
And the control principle is decentralized, centralized and hybrid control three.
