Source type output module (2 line type).SI-200/250 fiber optic cable.
Double loop.
Remote station.
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 AJ35T-M08B-K AJ35T-M08B-K
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 AJ35T-M08B-K . . Storage capacity: 64MB.
Applicable models: A985 (-V) /A975/A970/A960GOT (-B). Category: slave station.
Transfer speed: 125kbps/250kbps/500kbps/1Mbps.
Transmission line form: bus system.
Total distance: 125kbps:1000m/250kbps:800m/500kbps:480m/1Mbps:240m AJ35T-M08B-K .
The maximum connection units: 32.
Total points: input + output <=2048 point.
MITSUBISHI PLC detection, fault diagnosis and display and other procedures.
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. Input voltage range: AC100 ~ 120V/AC200 ~ 240V.
Output voltage: DC5/12V.
Output current: 2.3A/1.5A.
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 the analog quantity and switch quantity of the controlled object,
Generally an input / output element to take up an input / output point.
Taking into account the future adjustment and expansion,
In general should be estimated on the total number of points plus the amount of spare 20%~30%.
The following describes the centralized control system I/O points of the estimate.
Relay output interface circuit of PLC
Working process: when the internal circuit output digital signal 1,
There is a current flowing through, the relay coil has a current, and then the normally open contact is closed,
Provide load current and vvoltage AJ35T-M08B-K User's Manual.
When the internal circuit outputs a digital signal 0, there is no current flowing through it,
The relay coil does not have a current, and the normally open contact is broken off,
A current or voltage that is discoonnected from the load AJ35T-M08B-K User's Manual.
It is through the output interface circuit to the internal digital circuit into a signal to make the load action or not action.
