Omron FINS Write from ThingsBoard

I am using node-red for the very first time to do data monitoring and remote control on VFD by using OMRON CP1H. I managed to do the data monitoring part. However, I plan to use a control knob (RPC) to control the speed of the drive. I hope to send the controlled value to the plc via OMRON FINS write. However, what node i should use to get the value set from the user side and what setting i should use to write addresses CIO 200 and 201? Thanks in advance for the answer
