Slave I/O unit with DeviceNet or CANopen protocol

Slave I/O unit with DeviceNet or CANopen protocol DeviceNet and CANopen are two popular protocols applied in automotive industry. The unit is installed either of the two firmwares. It follows the CANopen Spec DS-301 V4.01 and DSP-401 V2.1, and supplies many features for users, such as dynamic PDO, EMCY object, error output value, SYNC cyclic and acyclic, … and etc.Therefore PC, HMI or PLC can uses DeviceNet or CANOpen protocol to communicate with I/O modules in the unit via the CAN bus interface.
