You have multi MASTER and SLAVE on one RS485-Bus. as modbus standard structure, one device can't both work as SLAVE and MASTER. Sorry, we can't do that auto feedback, it's not suitable for standard modbus structure.

We can try !

When two kcs868-Axx boards, connected on the same bus, send commands and feedback to each other with 'modbus-controller', they both work as SLAVE and MASTER .
Just have to incorporate delays in the reply.
