MITSUBISHI QJ71MB91

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 / output points: 4096 points.

Number of input and output elements: 8192.

Program capacity: 130 K step.

Processing speed: 0.0095 s.

Program memory capacity: 520 KB.

Support USB and network.

Support installed memory card.

Providing high speed communication between multiple CPU.

Shorten the fixed scan interrupt time, high precision device MITSUBISHI QJ71MB91. 

The minimum interval of the fixed period interrupt program is reduced to 100 s QJ71MB91

The high speed signal can be accurately obtained, which makes the contribution to the higher precision of the device.

High speed and high precision machine control by multi CPU.

By parallel processing of the linear and multi CPU high-speed communication (cycle 0.88ms) of the parallel control program, the high speed control MITSUBISHI QJ71MB91. 

Multi CPU high speed communication cycle and motion control synchronization, so it can achieve the maximization of computing efficiency.

In addition, the latest movement control CPU in performance is 2 times the previous model,

To ensure high speed and high accuracy of the machine control.High performance type CPU, process CPU, memory card protection cover for redundant CPU MITSUBISHI QJ71MB91. 

Q3MEM-4MBS-SET bundled products.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 MITSUBISHI MODBUS module. 

Perfect match with stepper motor control.

Plus deceleration smooth, speed change subtle.

To speed up the speed of positioning control to start processing MITSUBISHI MODBUS module. 

Positioning module.

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 MODBUS module. 

(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.

Thrrough regular backup, can be the latest parameters, procedures, etc QJ71MB91. 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 QJ71MB91. 

Therefore, it is not necessary to spend time to manage the backup data, but also can shorten the recovery time of the system shutdown.
