Multiple CPU units for A3VTS multiplex system.
Modular: PLC is the basic components of a separate module.
Medium and large PLC used this way. Easy maintenance.
User program storage capacity: it is a measure of how much the user application can store the number of indicators.
Usually in words or K words as units. 16 bit binary number is a word,
Every 1024 words are 1K words. PLC to store instructions and data in words A2NCPU
General logical operation instructions each account for 1 words. Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4.
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.
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.
It is through the output interface circuit to the internal digital circuit into a signal to make the load action or not action. Input voltage range: AC100-240V.
Output voltage: DC5V.
Output power: 8.5A.
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 battery,
To prevent the loss of the program and the parameters due to forgetting to replace the battery.
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 other planned downtime,
The data is lost due to battery depletion.
The next time the power is turned on, the backup data will be automatically restored.
