1MB extended memory.
Applicable models: A985 (-V) /975/970/A960GOT (-B) /A956WGOT A1SJHCPU-S8 PDF. Input and output points: 480 points.
Program capacity: 7K step.
Basic command processing speed: 4.4 ~ 5.6us.
Power supply: input AC100 ~ 120/200 ~ 240V/ output 2A DC24V, 0.5A DC5V.
Modular: PLC is the basic components of a separate module A1SJHCPU-S8
Medium and large PLC used this way. Easy maintenance.
User program storage capacity: it is a measure of how much the user application can store the number of indicators A1SJHCPU-S8 PDF.
Usually in words or K words as units. 16 bit binary number is a word,
Every 1024 words are 1K words. PLC to store instructions and data in words.
General logical operation instructions each account for 1 words. Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4 A1SJHCPU-S8 PDF.
Relay output interface circuit of PLC
Working process: when the internal circuit output digital signal 1,
There is a current flowing through, the relay coil has a current, and then the normally open contact is closed,
Provide load current and voltage.
When the internal circuit outputs a digital signal 0, there is no current flowing through it,
The relay coil does not have a current, and the normally open contact is broken off,
A current or voltage that is disconnected from the load MITSUBISHI User's Manual.
It is through the output interface circuit to the internal digital circuit into a signal to make the load action or not action MITSUBISHI User's Manual. 2 channels.
200/10kpps.
Count input signal: RS-422-A (gap dynamic appearance of rye).
External input: RS-422-A (gap dynamic appearance rye).
Compare output: transistor DC12/24V, 0.5A/1 point, 2A/1 common.
20 point terminal station.
Structured text language is a programming language that describes a program with a structured description of the text MITSUBISHI User's Manual.
It is a programming language similar to a high level language. In large and meddium
Structured text is often used to describe the relationship between the various variables in the control system based on the PLC system A1SJHCPU-S8 Manual .
Mainly used for other programming languages more difficult to achieve the user program.
Sequential function flow chart language is designed to satisfy the sequential logic control.
The process of sequential process action is divided into steps and transformation conditions,
According to the transfer condition, the control system is distributed in the function flow sequence,
Step by step according to the sequence of actions.
Each step represents a control function, represented by the box.
In the box, the ladder logic is used to complete the task of the corresponding control function.
This programming language makes the program structure clear and easy to read and maintain,
Greatly reduce the programming workload, shorten the programming and debugging time.
Used in the system of the size of the school, procedures for more complex occasions.
Sequence function flow chart programming language features: to function as the main line, in accordance with the functional flow off the order of distribution, clear, easy to understand the user program,
Avoid the defect of ladder diagram or other languages,
At the same time, the use of ladder language to avoid the use of ladder programming,
Due to the compllicated mechanical interlock, the structure of the user program is complex and difficult to understand,
User program scan time is also greatly reduced A1SJHCPU-S8 Manual A1SJHCPU-S8 User's Manual.
