QJ72BR15 Coaxial bus module Coaxial bus system Using low cost coaxial cable, the network construction cost is lower than that of the optical fiber loop network MITSUBISHI QJ72BR15

MODBUS RTU/MODBUS ASCII Master slave station.
RS-232.
RS-422/485.
MODBUS interface module capable of connecting MODBUS compatible device such as temperature regulator, measuring device and so on.
Support MODBUS communication function, and can be compatible with the third party MODBUS to communicate from various station equipment QJ72BR15.
Support MODBUS communication functions from thee station, can communicate with the third party programmable controller MODBUS master device.
Through the linkage function, the master can be connected to the CH1 side (RS-232),
And through the QJ71MB91 and connected to the CH2 side (RS-422/485) of a number of stations for communication QJ72BR15.
The RS-232 interface (1 credit on the 1 pass) MODBUS master device with multiple MODBUS communication from the station equipment QJ72BR15. (only QJ71MB91)
Master / slave station functions can be used simultaneously. (only QJ71MT91)1 axes, open collector output type.
Control unit: mm, inch, degree, pulse.
Location data: 600 data / axis.
Maximum pulse output: 200Kpps.
40 pin connector.
Positioning module MITSUBISHI QJ72BR15.
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 QJ72BR15.
(the command pulse of the open collector positioning module is highest 200kpps.)
3C-2V/5C-2V coaxial cable.
Single bus.
Remote I/O net (remote I/O station).
MELSECNET/H network module capable of composing large scale flexible network system MITSUBISHI QJ72BR15.
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 nettwork construction cost is lower than that of the optical fiber loop network QJ72BR15.
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.
