8 slot, PID special substrate.
When the programmer input programinto the user program memory,
Then CPU according to the function of the system (the system program memory to explain the compiler),
Translate the user program into PLC internally recognized by the user to compile the program.
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 voltage Q172J2BCBL1M-B
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 disconnected from the load Q172J2BCBL1M-B.
It is through the output interface circuit to the internal digital circuit into a signal to make the load action or not action.
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 Q172J2BCBL1M-B.
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. Power: 22kw.
Voltage: 200V.
The surge voltage of the motor can be suppressed when the 400V motor is driven by a frequency converter.
Motor suitable for 5.5 to 37kW. Input voltage range: AC100-240V.
Output voltage: DC5V/24V.
Output power: 0.6A.
Simplified program debugging.
Can use the software with the implementation of the conditions of the test function, any step in the program,
Changes the value of the soft component to a user specified value.
In the past, when debugging the specific loop process, the need to add a set of soft components of the program,
At present, through the use of the function, no need to change the program, you can make a specific loop program segment execution action.
Therefore, do not need to change the program separately in order to debug, debugging operation is more simple.
Through the expansion of soft components, more convenient to create the program.
M soft components and B soft components can be expanded to 60K points, making the program easier to understand.
Auto backup key data.
Save the program and parameter files automatically to the program memory (ROM Flash) without using the backup batteery,
To prevent the loss of thhe program and the parameters due to forgetting to replace the battery MITSUBISHI Q172J2BCBL1M-B.
In addition, the soft component data and other important data can be backed up to the standard ROM,
In order to avoid during the long holiday and oothher planned downtime,
The data is lost due to battery depletion MITSUBISHI Q172J2BCBL1M-B.
The next time the power is turned on, the backup data will be automatically restored.
