Cable 3M for the expansion of the floor, the expansion of a floor for every 1 units.8 channels.
Input: DC0 ~ 20mA.
Output (resolution): 0 ~ 4000/0 ~ 8000/0 ~ 12000.
Transform speed: 40ms/8.
38 point terminal station.
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 A970GOT-TBD-CH Manual.
And then combine the data and the program with CPU
A970GOT-TBD-CH
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.
PLC selection with the development of PLC technology, more and more types of PLC products,
Function is becoming more and more perfect, and its application is more and more extensive A970GOT-TBD-CH Manual.
Different series of different models of PLC has different performance, applicable occasions also have different emphasis,
Price also has a greater difference. Therefore PLC selection,
Under the premise of meeting the control requirements,
Should consider the best performance to price ratio, a reasonable choice of PLC.
The working process of the input interface circuit: when the switch is closed, the diode light,
The transistor is then guided to the internal circuit and input signal under the irradiation of the light A970GOT-TBD-CH Manual.
When the switch is off, the diode does not emit light, and the transistor is not on the way MITSUBISHI touch screen Manual. Internal circuit input signal.
It is through the input interface circuit to the external switch signal into PLC internal can accept the digital signal MITSUBISHI touch screen Manual.
MITSUBISHI PLC is the main product in the production of MITSUBISHI motor in Dalian.
It uses a kind of programmable memory for its internal storage procedures,
Execute logic operation, sequence control, timing, counting and arithmetic operations, user oriented instruction,
And through digital or analog input / output control of various types of machinery or production process MITSUBISHI touch screen Manual. The A1SD61 high speed counting module can receive up to 50KHz of pulse signals,
The signal can be counted when the input pulse is rising and the falling time is greater than 500.
This component has a 32 bit signed binary count range,
Counter can be preset, can also use the external signal or the control program will stop counting.
Structured text language is a programming language that describes a program with a structured description of the text.
It is a programming language similar to a high level language. In large and medium
Structured text is often used to describe the relationship between the various variables in the control system based on the PLC system.
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 of tthe 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 A970GOT-TBD-CH Manual A970GOT-TBD-CH Operating Manual.
