CiA 304 SRDO Add-on for CANopen Source CodeSYS-SO-1059
CiA 304 SRDO Add-on to CANopen Master & Slave Source Code
SRDO allow for a safe transmission of process data just as PDO do. To fulfill safety requirements, SRDO have special features and transmission behavior. A SRDO consist of two CAN messages (redundancy), which are transmitted cyclically, with inverted data content, different CAN-identifier and a strict transmission timing. On consumer side, SRDO are monitored and checked towards their transmission timing, sequence-order and data consistency.
The SRDO add-on module includes a special plug-in for the CANopen Device Monitor (part of the CANopen Configuration Suite), which provides an interface for consistent configuration of Safety Relevant Data Objects of a CANopen device.(requires SO-877, SO-877-VP, SO-1063 or SO-1063-VP)
