Non protocol, i know that fx1n does not support modbus rtu so that i wan to use rs contruction to write frequency from plc to inverter, do you have the code???

Hello @huuquyen.

The inverter supports Modbus protocol.

Select Modbus ASCII mode.

The best regards,

@huuquyen: You cannot simply use "RS" instruction to trigger Modbus commands. So it doesn't matter if you get the code for writing a Modbus command via RS instruction, you have to build a telegram first. Depending on you budget I would recommend upgrading the PLC to a newer version to get Modbus functionality. Alternatively you can download a function block from Mitsubishi, ready-made including the FX1N (note that you need the BD card): Search for "FXModbusRTUMaster_V200". It's a zip file with a project (GX IEC Developer) but you can use the library file in GX Developer too by selecting to use label in your project. Note that the FX1N is very limited regarding steps, so you might have a too large project...
