3C-2V/5C-2V coaxial cable between the single bus PC network (control station / common station) / remote I/O network (remote master).
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,
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.
This phenomenon is called the I/O delay time effect.
According to the current input combination of the switch quantity and the history of the input sequence,
In order to make the system work in a certain order.
So, sometimes also known as the order control.
And sequential control is divided into manual, semi-automatic or automatic.
And the control principle is decentralized, centralized and hybrid control three.
Ethernet network module 10BASE-T / 10BASE5.Input voltage: AC100-240V.
Rated output: DC5V, 5A.
The power supply module is connected with the external power supply,
AnS programmable controller to provide the required DC5V,
They are inserted in the slot of the special power supply component on the base board,
The output of the DC5V is powered by the power supply on the substrate to the component MITSUBISHI A1SJ71BR11
A1SJ71BR11
The input voltage of the component is related to the selected model.

Functional block diagram language is a kind of PLC programming language, which is similar to digital logic circuit MITSUBISHI A1SJ71BR11.
The function module is used to represent the function of the module,
Different function modules have different functions.
Functional module figure programming language features: functional block diagram programming language is characterized by a functional module for the unit,
Analysis and understanding of the control scheme is simple and easy: function module is to use graphical form of expression,
Intuitive, for a digital logic circuit based on the design of the staff is very easy to master the programming;
Control system with complex scale and complex control logic,
Because the function module diagram can clearly express the function relation, the programming debugging time is greatly reduced MITSUBISHI A1SJ71BR11 MITSUBISHI Network module MITSUBISHI Network module. I/O points: 1024.
Processing speed: 0.09 sec/ 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.
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 MITSUBISHI Network module.
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. Program memory capacity: 8k.
Input / output points: maximum 256 points.
A scan cycle of PLC must pass tthrough three stages: input sampling, program execution and output refresh A1SJ71BR11.
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 MITSUBISHI A1SJ71BR11.
