Twisted pair cable.
Single bus.
Controller network (control station / common station).
MELSECNET/H network module capable of composing large scale flexible network system.
The MELSECNET/H network system includes the PLC network of the control station and the communication between the stations and the remote I/O network in the remote station remote I/O station QD75P1N datasheet PDF catalog QD75P1N PDF datasheet
QD75P1N
Optical fiber loop system...... High speed communication of 10Mbps/25Mbps is realized.
The distance between stations, the length of the total cable length, strong anti-interference.
Coaxial bus system...... Using low cost coaxial cable, the network construction cost is lower than that of the optical fiber loop network.
Twisted pair bus system QD75P1N datasheet PDF catalog QD75P1N PDF datasheet. ..... Combined with high performance price ratio network module and twisted pair cable,
The construction cost of network system is very low.Input and output points: 1024 points.
Input / output data points: 8192 points.
Program capacity: 60k.
Basic command processing speed (LD command) S:0.2.
PLC in the program execution stage: according to the order of the user program order to store the order of each instruction,
After the corresponding operation and processing, the result is written to the output status register,
The contents of the output status register are changed with the execution of the program QD75P1N datasheet PDF catalog QD75P1N PDF datasheet.
Output refresh phase: when all instructions are executed,
The output status register is sent to the output latch in the output refresh stage,
And through a certain way (relay, transistor or transistor) output, drive the corresponding output equipment. 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 battery,
To prevent the loss of the program and the paraameters due to forgetting to replace the battery QD75P1N datasheet PDF catalog QD75P1N PDF datasheet.
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 oother planned downtime,
The data is lost due to battery depletion QD75P1N datasheet PDF catalog QD75P1N PDF datasheet.
The next time the power is turned on, the backup data will be automatically restored.
