Both TMLCAN and TechnoCAN protocols allow a Technosoft drive to communicate via CAN bus using TML (Technosoft Motion Language) instructions.

TMLCAN is based on CAN-BUS 2.0B specifications, with a 29 bit identifier.

TechnoCAN is based on CAN-BUS 2.0A specifications, with a 11 bit identifier. It was specifically designed to allow TML communication between Technosoft drives/motors and a host on a CANopen network, without interfering with the CANopen standard messages. The only limitation of TechnoCAN compared to TMLCAN is the supported number of axes (31 axes vs 255).
