MITSUBISHI A1SCPU Product information and technical parameters:
Brand: MITSUBISHI
Name: CPU unit
Model: A1SCPU
Program memory capacity: 8k.
Input / output points: maximum 256 points.
A scan cycle of PLC must pass through three stages: input sampling, program execution and output refresh.
PLC in the input sampling phase: first of all, in order to scan the sequence of all existing input latches in the input terminal of the state or input data read,
And write it into the corresponding input status register,
Refresh the input, then close the input port, enter the program execution stage.

Input type: AC.
Input points: 16 points.
Input voltage: AC200-240V.
Input current: 9mA.
Connection mode: terminal row.
Common common point: 16.
The instruction list programming language is a programming language similar to assembly language mnemonic,
As well as assembly language by the operation code and the number of operations A1SCPU.
In the case of the computer for the PLC handheld programmer compile user program A1SCPU
At the same time, the programming language of the instruction list corresponds to the ladder diagram programming language,
In PLC programming software can be converted to each other. Figure 3 is the instruction sheet corresponding to the ladder diagram of figure 2PLC.
The characteristics of instruction table programming language is used to represent mnemonic operation function,
Easy to remember, easy to grasp;
In the handheld programmer on the keyboard using the mnemonic representation, easy to operate, can be programmed in computer;
There is a one-to-one correspondence between the ladder diagram and the ladder diagram A1SCPU. Its characteristics are basically consistent with the ladder diagram language A1SCPU. I/O slots: 8 slots.
Can you install the power module.
Outline dimension: 365*130.
There are two types of extended floor,
A power module can be inserted, and the other one is not.
The choice of any type of substrate depends on the total DC5V current consumption and the power supply on the CPU main substrate.
If the total demand is less than the power output, no additional power supply,
Then you can choose a more economical expansion board.
Both ends of the main base plate of the CPU have an expansion interface, and can be used for extending the cable connection. Ethernet network module 10BASE-T / 10BASE5.Input and output points: 512 points.
Input / output data points: 8192 points.
Program capacity: 14K.
Basic command processing speed (LD command) s:0.2.
Internal storage RAM memory capacity: 64K
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 result is written to the output status register,
The contents of the output status register are changed with the execution of the program A1SCPU.
Output refresh phase: when all instructions are executed,
The output status register is sent to the ouutput latch in the output refresh stage,
And through a certain way (relay, transistor or transistor) output, drive the corresponding output equipment A1SCPU. .
