8 channels.
Input: DC-10 ~ 10V/DC4 ~ 20mA.
Output (resolution): -1000 ~ 1000, -2000 ~ 2000.
Transform speed: 2.5ms/1 channel.
47 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 A1SJ71QE71N-B5 Manual.
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 A1SJ71QE71N-B5
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 A1SJ71QE71N-B5 Manual. 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 A1SJ71QE71N-B5 Manual.
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 A1SJ71QE71N-B5 User's Manual.
MITSUBISHI PLC is the main product in the production of MITSUBISHI motor in Dalian MITSUBISHI A1SJ71QE71N-B5 User's Manual.
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 A1SJ71QE71N-B5 User's Manual. Program memory capacity 14K.
Input and output points to the maximum 512 points.
A scan cycle of PLC must pass tthrough three stages: input sampling, program execution and output refresh A1SJ71QE71N-B5 Hardware.
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 A1SJ71QE71N-B5 Manual.
