Mitsubishi FR-E700 & Visual Studio C# via “Modbus RTU”

Hello friends!
In previous articles, plc247.com introduced to you how to use Visual Studio C# to connect to different PLCs to control or store data. Today plc247.com will use C# to control the Mitsubishi FR-E700 Series.

With this program we can easily control any inverter from Mitsubishi or other brands following the Modbus-RTU standard.

======

Using Visual Studio to connect to a VFD has the following advantages:

+ Connects to all Mitsubishi (or Delta, Danfoss, Fuij…) VFDs: Just need the inverter to support Modbus-RTU communication standard

+ Easy customization, can store all vfd memory areas.

+ The software is completely free, can package Windows applications and use an unlimited number of computers

+ Connect, monitor, and store data quickly with just a computer, no PLC needed… saving costs and time for businesses

I will Show Control Panel as well as 100% C# Source Code, but I do not share the Program. You need to learn for yourself to improve your skills:

Mitsubishi FR E700 Modbus RTU Parameters Setting

Below are the communication parameters that need to be set up of the FR E700 inverter that can communicate with Modbus RTU:

• Pr117 = 1 (Address Slave Number)
• Pr118 = 3 (9600bps)
• Pr119 = 0 (8bit/Stop:1bit)
• Pr120 = 2 (Parity: Even)
• Pr121 = 9999
• Pr122 = 9999
• Pr123 = 9999
• Pr124 = 1
• Pr340 = 1
• Pr549 = 1
• Pr79 = 2 (Last Setting)

Register for Control Address

Address where holding register data write will be started Starting address = “Starting register address (decimal)-40001”

>>> Register Control Address = 40009 – 40001 = 8

• Set Word 8 = 2 >>> Forward Run
  = 4 >>> Reverse Run
  = 0 >>> Stop

>>> Register Frequency Reference = 40014 – 40001 = 13

Register for Monitoring Address

In the plc247.com project read 3 consecutive registers including: 40201, 40202, 40203

• Output Frequency = 40201 – 40001 = 200 / Number Registers = 3
