Nuremberg, Germany, 2025-12-08. The nonprofit CAN in Automation (CiA) association has released the second version of the CiA 319 specification. It specifies how to implement and to configure functional-safe devices compliant to EN 50325-5 (CANopen Safety). CANopen Safety services and protocols are used especially in mobile machines and industrial machine control. The European standard does not specify the configuration of functional-safe devices; this is given in detail in CiA 319.
“This document fills the gap und helps CANopen Safety system designers to safely set-up networks,” explained Holger Zeltwanger, CiA Managing Director. “Additionally, this document addresses editors of CANopen device profiles using SRDO (safety-related data objects as specified in EN 50325-5.” SRDOs comprise two CAN frames with bitwise-inverted CAN data fields and different CAN identifiers. CANopen Safety is approved up to SIL 3 (safety integrity level).
