I am now trying to have my master motor (SM34165DT) to send basic orders (change variable values) in a programmable stepper motor driver (LAM Technologies) using RS485.
I set up same parameters in both devices. Stepper driver is running with Modbus RTU Protocol.
If compatible, how should I send messages (in data mode or command, which synthax...)?
Exemple: Driver Adress: 10
Adress of word to modify: 0xA002
