Type of input: DC leakage.
Input points: 64 points.
Input voltage: DC24.
Input current: 5mA.
Connection mode: terminal row.
Common common point: 32.
Functional block diagram language is a kind of PLC programming language, which is similar to digital logic circuit.
Different function modules have different functions.
Functional module figure programming language features: functional block diagram programming language is characterized by a functional module for the unit,
Analysis and understanding of the control scheme is simple and easy: function module is to use graphical form of expression,
Intuitive, for a digital logic circuit based on the design of the staff is very easy to master the programming;
Because the function module diagram can clearly express the function relation, the programming debugging time is greatly reduced.
Liquid crystal display: 16 characters x 2 lines,
For data access (the state of operation of the central processor, device monitor / change). Using a modem middle modular connector unit faces to transmit data transmission speed: 0.3-14.4kbps.
PLC is the use of " sequential scanning, and constantly circulating " way to work MITSUBISHI A1SX42-S2.
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 A1SX42-S2

Also complete the sampling of the input signal and the output status of the refresh and other work MITSUBISHI A1SX42-S2. Input and output points: 1024 points.
Input / output data points: 8192 points.
Program capacity: 60k.
Basic command processing speed (LD command) S:0.2.
PLC in the program execution stage: according to the order of the user program order to store the order of each instruction,
After the corresponding operation and processing, the reesult is written to the output status register,
The contents of the output status register are changed with the execution of the program A1SX42-S2.
Output refresh phase: when all instructions are executed,
The output status register is sent to the ooutput latch in the output refresh stage,
And through a certain way (relay, transistor or transistor) output, drive the corresponding output equipment A1SX42-S2.
