The SilverDust IGC CANopen servo motor single axis controller includes serial communications (RS-232, RS-485), CANopen, and 7 I/O. CANopen can be configured for peer-to-peer, master, or slave, which allows the controllers to share I/O with other CANopen enabled SilverDust controllers or 3rd party CANopen devices (e.g., I/O blocks, encoders, etc.) The RS-232/RS-485 serial network runs in parallel to CANopen for supervisory control from a host (e.g., PC, PLC, HMI.)
