• Ⓐ Target Station IP Address is set by default at ”192.168.1.20”
• Ⓑ The station number to be connected
• Ⓒ From the drop-down menu, select “0505h:Read/Write Holding Registers”
• Ⓓ Set to 1000h
• Ⓓ The Target MODBUS Device Head Number is set to 4096
• Ⓕ Read Points
• Ⓖ Set to 3000h
• H The Target MODBUS Device Head Number is set to 8192
• Ⓘ Write Points

Notes

• first GFDI-RM01N has the register address at 1000(HEX) converted to 4096
• first GFDO-RM01N has the register address at 2000(HEX) converted to 8192

1. Click on “Auto_Refresh” to set up the internal register for reading and writing

Simple Program

Simple Program Demonstration using MELSEC-Q series and

• The read register address is 4096, which is D0 for the corresponding internal register of the controller.
• And the write register address is 8192, which is D300 for the corresponding internal register of the controller.
• Therefore, when you want to control the program, you can just use the internal register to control the writing and reading.
