MITSUBISHI QJ71LP21G Optical fiber loop (GI) module
Brand: MITSUBISHI
Name: Optical fiber loop (GI) module
Model: QJ71LP21G
GI-50/125 optical cable.
Double ring.
PLC to PLC 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.

10BASE-T/100BASE-TX.
Ethernet interface module capable of selecting the most suitable system and object device.
Support 100BASE-TX, can speed up the transmission speed. (QJ71E71-100)
Data communication can be performed between programmable controller CPU using special instructions.
Can use the HTTP protocol, through the Web browser on the PC access to the soft element of the programmable controller MITSUBISHI QJ71LP21G QJ71LP21G
PC (Web) on the use of the communication program library and sample screen can be obtained by download services.
Can connect a number of programming tools to improve the efficiency of debugging.
Make use of e-mail function, through the mail server to send e-mail (ASCII format) and attachments (binary, ASCII and CSV format) MITSUBISHI QJ71LP21G.
The KeepAlive function can be used to perform the existence of the object equipment inspection, and keep the connection in the open state.
This can be used to ensure connectivity and to quickly find errors. Program capacity: 8K step.
Input / output points: 256 points.
Number of input and output elements: 2048.
Power +5 tank bottom plate of the CPU.
Continue to go beyond, to climb the peak of Q series MITSUBISHI QJ71LP21G.
Strengthen security function.
Can be set up to 32 characters of the file password.
In addition to the English letters, numbers, but also the use of special characters,
To further enhance the security of the password.
In addition, only pre registered devices are allowed to access CPU,
To intercept unauthorized access to unauthorized users.
Therefore, it is important to prevent the outflow of important program assets and protect intellectual property rights.
CPU module expansion standard RAM (max 8MB).
Can be used with the SD memory card at the same time.
Continuous access file register.Input: 4 channels.
Thermocouple (K, J, T, B, S, E, R, N, U, L, PLlI, W5Re/W26Re,,).
Heater disconnection detection function.
Sampling period: 0.5s/4 channel.
18 point terminal table x2.
Peak current suppression.
Can prevent the simultaneous opening of the output to control the peak current, which is helpful for saving energy and reducing the operation cost.
Heating function at the same time.
The multiple loop can reach the set value at the same time to carry out the uniform temperature control,
Helps to prevent no-load and effective energy saving and reduce operating costs.
Automatic adjustment function.
The PID constant can be adjusted automatically in the control process.
Automatic adjustment of cost (time, material and electrical energy) can be reduced.
Can be flexible in various settings, to achieve the best temperature control of the temperature control module.
Equipment for high temperature control stability of extrusion moldinng machine,
The temperature regulating module has the function of preventing overheating and preventing over cooling QJ71LP21G.
According to the control object device, select the standard control (heating or cooling) or the heating and cooling contrrol (heating and cooling) mode QJ71LP21G.
In addition, the mixed control mode (combined with the standard control and heating - cooling control) can be selected.
