MITSUBISHI QJ71MB91 Product information and technical parameters:
Brand: MITSUBISHI
Name: MODBUS module
Model: QJ71MB91
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.
Support MODBUS communication functions from the 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.
The RS-232 interface (1 credit on the 1 pass) MODBUS master device with multiple MODBUS communication from the station equipment. (only QJ71MB91)
Master / slave station functions can be used simultaneously. (only QJ71MT91)

Input: 2 channels.
10kpps.
Counter input signal: DC5/12/24V.
External input: DC5/12/24V.
Uniform output: Transistor (drain type).
Used to replace the A series of large modules "AD61-S1".
40 pin connector.
Support high resolution devices. Pulse input and high speed counter module product group satisfying high speed and high precision control application MITSUBISHI QJ71MB91.
High speed counter module for counting high-speed pulse train QJ71MB91
Can be used in combination with the external encoder for positioning and other control.
The maximum count rate can be switched, and the low frequency pulse is counted from the high speed pulse to the rising edge / falling edge.
Each 1 channel is equipped with 2 points of external uniform output MITSUBISHI QJ71MB91.
Can be selected according to the use of "consistent output function", "continuous comparison function", to achieve high-speed control of external equipment. (QD64D2)
Provides a variety of functions, such as the same output test function (using a continuous comparison function), the default function, the latch counter function,
In order to meet the needs of various applications. (QD64D2)
The maximum count rate of the input pulse can be up to 8Mpps (differential input, 2 phase, 4 double frequency) MITSUBISHI QJ71MB91.
Can be in the semiconductor, liquid crystal manufacturing and other high position accuracy requirements of the equipment,
Perform accurate position tracking using high resolution encoders. (QD65PD2)Output points: 16 points.
Output voltage and current: DC12~24V; 0.5A/ point; 4A/ common.
OFF leakage current: 0.1mA.
Response time: 1ms.
16 points and 1 common ends.
Source type.
18 point terminal station.
With the surge absorber.
With fuse.
Ultra high speed processing, production time is shortened, better performance.
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 determinne the data transceiver time between the CPU module QJ71MB91.
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 QJ71MB91.
And the sampling tracking results can be stored in LogViewer GX form CSV,
By recording data display and analysis tool LogViewer GX to display.
