CANopen SDO/PDO Message Frame Decoder
Decodes CANopen COB-IDs into function codes and Node-IDs.
Notice: engineering verification utility. Use test or de-identified data and verify results independently before relying on them.
How it works
Standard: CiA 301 CANopen Application Layer
Formula: FunctionCode = COB_ID >> 7, NodeID = COB_ID & 0x7F
Checks: COB-ID within standard 11-bit range (0x000 to 0x7FF)
