Modbus RTU nodes with DE and RE control

Hi everyone,

I am trying to communicate between an Arduino Leonardo based PLC: and a Raspberry based PLC: through Modbus RTU RS-485.

The fact is that the Touchberry Pi internally needs to control the DE and RE pins for Rs-485.

Does anyone know any Modbus nodes to control DE and RE pins? I tried some but I do not think they can do it

Thank you very much,
