OPC Unified Architecture – Part 22: Base Network Model
5.3.1.5 TsnFailureCode Enumeration
The TsnFailureCode is an Enumeration to provide detailed error information for failures occurring during TSN stream establishment (TSN Failure Codes are defined in IEEE 802.1Qcc-2018, Table 46-15, TSN Failure Codes). The TsnFailureCode Enumeration is defined in Table 26.
