The main unit of the AS-i system
The response time of PLC is the interval between the time of the change of the external output signal of the PLC and the time of the change of the external output signal which is controlled by it,
Lag time, this is the time constant of the input circuit,
The time constant of the output circuit, the arrangement of the user statement and the use of the instruction,
The cycle scan mode of PLC and the way of PLC to refresh the I/O and so on MITSUBISHI Serial communication module PDF datasheet AJ71QC24-R4
This phenomenon is called the I/O delay time effect.
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 MITSUBISHI Serial communication module PDF datasheet.
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. I/O points: 1024.
Processing speed: sec/ 0.15u step.
Memory capacity: 256K bytes.
Program capacity: 30K step.
PLC programming is a digital computing operation of the electronic system,
Designed for applications in industrial environments MITSUBISHI Serial communication module PDF datasheet.
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 AJ71QC24-R4 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 AJ71QC24-R4 PDF datasheet. 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 AJ71QC24-R4 PDF datasheet.
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 execuution stage AJ71QC24-R4 PDF catalog. Cable length: 3 meters.
