QJ71LP21S-25 MITSUBISHI QJ71LP21S-25 Optical fiber loop system High speed communication of 10Mbps/25Mbps is realized 
Brand: MITSUBISHI
Name: Optical fiber loop (SI) module
Model: QJ71LP21S-25
SI/QSI/H-PCF/ broadband H-PCF optical cable.
Double circuit.
Controller network (control station / common station) / remote I/O network (remote master station).
With external power supply function.
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.
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...... Combined with high performance price ratio network module and twisted pair cable,
The construction cost of network system is very low.

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 MITSUBISHI QJ71LP21S-25 QJ71LP21S-25
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 MITSUBISHI QJ71LP21S-25.
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 MITSUBISHI QJ71LP21S-25.
The next time the power is turned on, the backup data will be automatically restored MITSUBISHI Optical fiber loop (SI) module. For A6TBXE/A6TBY36E/A6TBX54E/A6TBY54E/A6TBX70E (common cathode; source) long 0.5m.Input: 4 channels.
Thermocouple (C1602-1995 JIS) MITSUBISHI Optical fiber loop (SI) module.
Conversion speed: 40ms/1 channel.
18 point terminal station.
Most suitable for process control of isolated analog modules.
Temperature data can be collected by connecting thermocouple / thermal resistance.
Products can choose multi-channel (8 channel) input type and channel isolation type MITSUBISHI Optical fiber loop (SI) module.
Customers can choose the most suitable model according to the intended use.
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.
Reduce system downtime recovery time.
With a simple operation, you can back up all the data in the CPU to the memory card.
Throughh regular backup, can be the latest parameters, procedures, etc QJ71LP21S-25. to save the storage card.
In the event of a CPU failure, after the replacement of CPU, can be a simple operation,
Restore the system by using the data storage ccard in advance MITSUBISHI QJ71LP21S-25.
Therefore, it is not necessary to spend time to manage the backup data, but also can shorten the recovery time of the system shutdown.
