Write on modbus node

[jlqautomacao]

Hi,
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

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.
