CC-Link master / slave station.
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.

RS-232 2 channel.
Transfer speed: 0.3-19.2kbps.
Input status and input information input from the input interface,
CPU will be stored in the working data memory or in the input image register.
And then combine the data and the program with CPU.
The result is stored in the output image register or the working data memory,
And then output to the output interface, control the external drive MITSUBISHI A1SJ61QBT11
A1SJ61QBT11
Semiconductor circuit with memory function.
System program memory and user memory.
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 MITSUBISHI A1SJ61QBT11. Output type: transistor source.
Output points: 16 points.
Load voltage: DC5/12/24.
Load current: 2A.
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 MITSUBISHI A1SJ61QBT11.
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.
And the control principle is decentralized, centralized and hybrid control three. I/O slots: 5 slots.
Could you install the power module.
Outline dimension: 315*130.
There are two types of extended floor,
A power module can be inserted, and the other one is not.
Thhe choice of any type of substrate depends on the total DC5V current consumption and the power supply on the CPU main substrate A1SJ61QBT11.
If the total demand is less than the power output, no additional power supply,
Then you can choose a more ecconomical expansion board A1SJ61QBT11.
Both ends of the main base plate of the CPU have an expansion interface, and can be used for extending the cable connection.
