I have a TEENSY 4.0 and multiple angular transducers ( Modbus-RTU supported). From each Angular transducer I have to read 8 words and write 2 words. But writing is occasional because it is used for presetting, Offset ,direction change etc.
Can anyone please provide me proper guidance to communicate with the devices. I have following hardware with me.

1. Teensy 4.0

2. TTL to rs485 (MAX 485 interface module)

3. Angular Transducer with Modbus support

4. Power supply 5v dc

5. wires and bread board
