I need to establish communication between a PLC (S7-1200) and multiple Propeller FLIP microcontrollers.
To achieve that, I'm planning on using an RS485 communication module and having all microcontrollers sharing the same RS485 bus.
Is this possible? PLC would be the master and all microcontrollers, slaves.
How can I set different addresses for all microcontrollers? And do I need an RS485 driver IC?
Thank you in advance!
