Communication protocols

Revo 2 supports up to three external interfaces: RS-485, CAN FD, and EtherCAT. Interface availability depends on the hardware variant.

Model	Description	Available protocols
V2-BASIC	Revo 2 Basic	Modbus RTU over RS-485 or CAN FD
V2-PRO	Revo 2 Pro	Check the model-specific protocol page and hardware configuration
V2-TOUCH	Revo 2 Touch	Check the model-specific protocol page and hardware configuration

Modbus RTU and CAN FD

The public protocol covers device configuration, motion control, and status reads. The SDK and desktop tool expose the same device capabilities at a higher level. A bus can host multiple hands or compatible devices when every device has a unique ID.

Revo 2 Basic uses the DIP switch below the wrist to select the interface. Set it to CAN FD for CAN FD, or to Modbus RTU for RS-485. Stop motion control before switching, then reconnect the device as required by the hardware.

EtherCAT

Use EtherCAT when the system requires deterministic cycles, low latency, and synchronized joint control. Joint commands and sensor feedback share the real-time bus. EtherCAT integration differs from Modbus RTU and CAN FD; follow the EtherCAT reference in this section.
