The CAN in Automation (CiA) association has released the second version of the CiA 319 specification. This 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.
“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).
