2 channels.
10/7kpps.
Count input signal: DC5/12/24V, 2-5mA.
External input: DC5V/DC12V/DC24V.
External output: Transistor (open collector) DC12/24V, 0.5A.
36 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 A2SCPU.
And thenn 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 A2SCPU.
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 A2SCPU. 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 MITSUBISHI A2SCPU.
When the switch is off, the diode does not emit light, and the transistor is not on the way. Internal circuit input signal MITSUBISHI A2SCPU.
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.
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 A2SCPU. Series Name: A985GOT.
Size: 12 inches.
Resolution: 800 * 600.
Display equipment: high brightness TFT color display.
Display color: 256 color.
Power supply: AC100-240V.
Man machine interface (Machine Interaction Human, referred to as HMI), also known as the user interface or user interface,
Is a communication interface between human and computer,
Is an important part of the computer system.
Is a medium for interaction and information exchange between the system and the user,
It realizes the transformation between the internal form of information and the acceptable form of human being.
Where there is a man-machine interface in the field of human computer information exchange.
Program memory capacity 14K.
Input and output points to the maximum 512 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 sccan 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 A2SCPU.
