v2-ci / unit-tests (push) Has been cancelled
No public source exists for DNC_ERROR_CLASS / DNC_ERROR_GROUP or their numbers (the table was written from memory). The iTNC 530 Technical Manual's PLC error table documents the same class and group NAMES without codes; three real iTNC 530 records corroborate 7/4, 7/3 and 1/3. DNC and LSV2 numberings are known to differ (ProgramStatus vs R_RI 26), so the numbers stay unproven. Docs/comments only; no behaviour change.
