This section compared with GB/T 14048.13-2006 main technical changes are as follows.

--- Added terms and definitions related to failure, level of safety performance and structural limitations, etc., deleting terms related to integrated circuits;

--- Added functional safety related specifications and usage information, and added performance to PDDB's ECM compatibility requirements Criteria and other aspects (see Chapter 7);

--- Deleted the control and monitoring device design requirements (see 7.1);

--- Deleted 8.7 "verification of determination of fault conditions" and 8.8 "Evaluation of programmable or composite integrated circuits" (see 8 chapters);

--- Added "amendment" chapter (see Chapter 9);

--- Standard full text is no longer related to integrated circuits and programming requirements, also deleted the original Appendix A "applied by the shadow of 8.7 and 8.8 LIST PDF Single Failure List of Electrical Equipment ", replace it with a new Appendix A (informative)" IEC 61511 compliant Column standard simple control system example.
