QJ71LP21-25 Optical fiber loop (SI) module MITSUBISHI QJ71LP21-25 MELSECNET/H network module capable of composing large scale flexible network system 
Brand: MITSUBISHI
Name: Optical fiber loop (SI) module
Model: QJ71LP21-25
SI/QSI/H-PCF/ broadband H-PCF optical cable.
Double circuit.
Controller network (control station / common station) / remote I/O network (remote master station).
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.

4 axis, differential drive output type.
Control unit: pulse.
Location data: 10 data / axis.
Maximum pulse output: 4Mpps.
40 pin connector.
Differential output.
Ideal solution for simple multi axis positioning.
Perfect match with stepper motor control.
Plus deceleration smooth, speed change subtle.
To speed up the speed of positioning control to start processing MITSUBISHI QJ71LP21-25.
Positioning module QJ71LP21-25
Open collector output.
Differential driver output.
Based on the use of open collector outputs and differential drive output type 2 types.
Differential driver output type positioning module can transmit high speed instruction pulse (up to 4Mpps) to the servo amplifier reliably,
Transmission distance of up to 10 meters, to achieve high speed and high precision control MITSUBISHI QJ71LP21-25.
(the command pulse of the open collector positioning module is highest 200kpps.)
Reduce system downtime recovery time.
With a simple operation, you can back up all the data in the CPU to the memory card.
Through regular backup, can be the latest parameters, procedures, etc. 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 card in advance MITSUBISHI QJ71LP21-25.
Therefore, it is not necessary to spend time to manage the backup data, but also can shorten the recovery time of the system shutdown. SD memory card 2GB.
Can be used on the Q24DHCPCPU-V MITSUBISHI Optical fiber loop (SI) module.
Can be used on the Q24DHCPCPU-LS.
Can be used on the QnUDVCPU.Output points: 32 points.
Output voltage and current: 24V ~ 0 MITSUBISHI Optical fiber loop (SI) module. 2A/1 DC5 point.
2A/1 common end.
OFF leakage current: 0.1mA.
Response time: 1ms.
16 points and 1 common ends.
Leaky type.
40 pin connector.
With heat protection.
With short circuit protection.
With the surge absorber.
Ultra high speed processing, production time is shortened, better performance MITSUBISHI Optical fiber loop (SI) module.
As applications become larger and more complex, it is necessary to shorten the system operation cycle time.
The operation period can be shortened by the super high basic operation speed 1.9ns.
In addition to achieve in the past with the control of single-chip high-speed control,
The system performance can be improved by reducing the total scan time,
To prevent any possible performance bias.
Convenient processing of large capacity data.
In the past can not achieve the standard RAM and SRAM card file register area of continuous access,
The boundary of each area should be considered in programming.
The SRAM 8MB extension card is installed in the high speed universal QCPU,
Standard RAM can be used as a continuous file register,
Capacity up to 4736K words, thus simplifying the programming.
Thus, even if the memory space of the soft element is insufficient,
Can also be installed by the expansion of SRAM card, easy to extend the file register area.
The address register is extended to 32 bits, which can be programmed to go beyond the traditional 32K word,
And to achieve the extension to the file register to all regions of the file register.
In addition, the processing speed of the index modification plays an important role in the efficient operation of structured data (array),
The speed has been improved.
When the index is used to modify the program repeatedly (e.g. from FOR to NEXT), the scan time can be reduced.
With the help of sample tracking function, the starting time is shortened
By using the sampling and tracking function, it is convenient to analyze the data when the fault occurs,
Testing procedures for the time, etc., can shorten the time of failure analysis and start-up time.
In addition, the multi CPU system also helps to determine the data traansceiver time between the CPU module QJ71LP21-25.
Can be used to analyze the data collected by programming tools,
In the form of charts and trend charts, the data changes of the bit soft element and the word soft element can be easily diisplayed MITSUBISHI QJ71LP21-25.
And the sampling tracking results can be stored in LogViewer GX form CSV,
By recording data display and analysis tool LogViewer GX to display.
