Twisted pair / rubber insulated cable.
Single bus.
LINK MELSEC-I/O (control unit).
According to the control requirements of the system, using the appropriate design method to design MITSUBISHI PLC program.
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 MITSUBISHI A70BDE-J71QLP23GE A70BDE-J71QLP23GE
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.
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 MITSUBISHI A70BDE-J71QLP23GE. . Input voltage: AC100 ~ 120V/AC200 ~ 240V.
Output voltage: DC5V.
Output current: 8A.
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 MITSUBISHI A70BDE-J71QLP23GE.
Different series of different models of PLC has different performance, applicable occasions also have different emphasis,
Price also has a greater difference. Therefore PLC selection,
Under the premise of meeting the control requirements,
Should consider the best performance to price ratio, a reasonable choice of PLC MITSUBISHI Communication module. Bus connection.
Program 2 channel connection.
MITSUBISHI PLC detection, fault diagnosis and display and other procedures MITSUBISHI Communication module.
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 MITSUBISHI Communication module.
It can avoid the control logic confusion caused by illegal operations. Input voltage range: DC110V.
Output voltage: DC5V.
Output current: 8A.
I/O points is an important indicator of PLC.
Reasonable selection of I/O points can not only satisfy the control requirements of the system,
And the total investment of the system is the lowest.
The input and output points and types of PLC should be determined according to thee analog quantity and switch quantity of the controlled object,
Generally an input / output element to take up an input / output point A70BDE-J71QLP23GE.
Taking into account the future adjustment and expansion,
In general should be estimaated on the total number of points plus the amount of spare 20%~30% MITSUBISHI A70BDE-J71QLP23GE.
The following describes the centralized control system I/O points of the estimate.
