Fiber optic cable / twisted pair cable.
Single bus.
Control unit.
According to the control requirements of the system, using the appropriate design method to design MITSUBISHI PLC program A0J2CPUR23 PDF.
Procedures to meet the requirements of system control as the main line,
Write one by one to achieve the control function or the sub task of the program,
Gradually improve the functions specified by the system A0J2CPUR23
MITSUBISHI PLC initialization procedure. After MITSUBISHI PLC on power, the general need to do some of the initial operation,
In order to start making necessary preparations, to avoid the wrong operation of the system A0J2CPUR23 PDF.
The main contents of the initialization program are: to some data area, counter and so on,
Data needed to restore some of the data area,
Set or reset some relays,
For some initial state display, etc.. Bus connection.
Program 1 channnel connection A0J2CPUR23 Manual.
MITSUBISHI PLC detection, fault diagnosis and display and other procedures A0J2CPUR23 PDF.
These procedures are relatively independent, generally in the basic completion of the program design and then add.
MITSUBISHI PLC protection and chain procedures.
Protection and chain is an indispensable part of the program, must be carefully considered.
It can avoid the control logic confusion caused by illegal operations MITSUBISHI Programming Manual . Type of input: DC leakage.
Input points: 32 points.
Input voltage: DC24.
Input current: 7mA.
Connection mode: terminal row.
Common common point: 32.
Functional block diagram language is a kind of PLC programming language, which is similar to digital logic circuit MITSUBISHI Programming Manual .
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 mmodule 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 thee function module diagram can clearly express the function relation, the programming debugging time is greatly reduced MITSUBISHI Programming Manual A0J2CPUR23 Manual A0J2CPUR23 Programming Manual .
