Write on modbus node

how do i write in modbus node with function 16, 4 bytes? Can someone help me?
I'm only able to read the modules, but I can't write.

Have you read the built in help?

4 bytes is 2 registers, you have set 4 registers (8 bytes)

Correct image, I made some modifications as the node too. But I still haven't.
I'm still new to node-red.
