Based on the technology of Intelligent Field Bus (CAN Bus), the CAN-8823 are control units which are designed for CANopen protocol slave devices. They have 8 slots for I/O expansion and works with many of ICP DAS USA's DI / AI / DO / AO modules. Following closely after the CANopen specifications of the DS-301 V4.02 and DSP-401 V2.1, the CAN-8823 features dynamic PDO, EMCY object, error output value, SYNC cyclic and acyclic, as well as providing for standardized communication for real-time data processing. This includes SDO (Service Data Object), network management data (NMT message, and Error Control), Time Stamp, Sync Message, and Emergency Message.
The CAN-8823 can be provided with a Utility that for dynamic creation of EDS files. The EDS, based on the CANopen DSP-306, can be compatible with different CANopen master interfaces.
