Available network: 10BASE2.
Max / total distance: 185/925m.
A1SJ71E71 is a compact Ethernet interface module,
Used to hang PLC series ANS to ethernet.
There are two kinds of hanging network modules: A1SJ71E71-B2-S3 and A1SJ71E71-B5-S3 respectively corresponding to 10BASE2 and 10BASE5,
So that the vast majority of installed cable can continue to use A68RD4 User's Manual. Input and output points: 224 points A68RD4
Input / output data points: 224 points.
Program capacity: 14K.
Basic command processing speed (LD command) s:0.25.
Internal storage RAM memory capacity: 64k.
Internal storage E2PROM memory capacity: 32k.
The popularization and application of PLC programming has been developed rapidly in our country,
It has been widely used in all kinds of mechanical equipment and production process of electrical control devices,
All walks of life have emerged a large number of application of PLC transformation of the results of the equipment A68RD4 User's Manual.
Understand the working principle of PLC, have the ability to design, debug and maintain the PLC control system,
Has become the basic requirements of modern industry for electrical technicians and engineering students A68RD4 User's Manual.
Switching value, also known as logic, refers to only two values, 0 or 1, ON or OFF.
It is the most common control, it is the advantage of PLC control,
Is also the most basic application of PLC MITSUBISHI A68RD4 Manual .
Structured text language is a programming language that describes a program with a structured description of the text.
It is a programming language similar to a high level language MITSUBISHI A68RD4 Manual . In large and medium-sized PLC systems, structured text is often used to describe the relationship between the variables in the control system.
Mainly used for other programming languages more difficult to achieve the user program.
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 MITSUBISHI A68RD4 Manual .
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. Pulse input: differential input.
Preset input: differential input.
Count range: 0~16777215.
Number of stations: 4 stops.
Station type: remote equipment station.
Configuration of master / local station,
In addition to the other site network with different CC-Link in addition to the main station and the remote station configuration can also be the main station and the local station configuration.
A local PLC can communicate with the master station PLC and other remote workstations.
MITSUBISHI PLC hardware implementation
Hardware implementation is mainly for the control cabinet and other hardware design and field construction.
Design control cabinet and the operating table and other parts of the electrical wiring diagram and wiring diagram.
Electrical interconnection diagram of each part of the design system.
According to the construction drawings of the site wiring, and carry out a detailed inspection.
Because the program design and hardware implementation can be carried out at the same time,
So the design cycle of the MITSUBISHI PLC control system can be greatly reduced.
MITSUBISHI PLC online debugging.
On-line debugging is the process that will through the simulation debugging to further carry on the on-linne unification to adjust A68RD4 .
On-line debugging process should be step by step,
From MITSUBISHI PLC only connected to the input device, and then connect the output device, and then connect to the actual load and so on and so on stepp by step A68RD4 User's Manual.
If you do not meet the requirements, the hardware and procedures for adjustment.
Usually only need to modify the part of the program can be.
