PLC programming is a digital computing operation of the electronic system,
Designed for applications in industrial environments.
It uses programmable memory,
An instruction used to perform logical operations, sequence control, timing, counting and arithmetic operations in its internal storage,
And through the digital, analog input and output, control of various types of machinery or production process AJ71C21-S1 datasheet PDF catalog AJ71C21-S1 PDF datasheet.
Programmable controller and related equipment,
Should be easy to make the industrial control system to form a whole, easy to expand the principle design of its functions. For common cathode input module (2 line type).16 channels.
Input: DC0 ~ 20mA.
Output (resolution): 0 ~ 4000.
Conversion speed: 0 AJ71C21-S1 datasheet PDF catalog AJ71C21-S1 PDF datasheet. 5ms * channel number +2ms.
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.
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.
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.
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.
When the switch is off, the diode does not emit light, and the transistor is not on the way. 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 PLC is the main product in the production of MITSUBISHI motor in Dalian AJ71C21-S1 datasheet PDF catalog AJ71C21-S1 PDF datasheet.
It uses a kind of programmable memory for its internal storage procedures,
Execute logic operation, sequence control, timing, counting and arithhmetic operations, user oriented instruction,
And through digital or analog input / output control of various types of machinery or production process AJ71C21-S1 datasheet PDF catalog AJ71C21-S1 PDF datasheet.
