Is this Modbus read and write instructions ?

If so, are you using Modbus TCP or RTU ?

For RTU you need FX3U-485-BD or FX3U-485-ADP/MB.

For TCP you need a FX3U-ENET/P502.

You can find Modbus libraries for the FX3U at the Mitsubishi homepage

@Choi07 You need to use FX3U-CNV-BD and FX3U-485ADP-MB to connect with Modbus parameter.

For MODRD and MODWR in Delta PLC you can convert to ADPRW in FX3U PLC.

For more information you should check FX3U Modbus manual as link below.
