修改記錄和變更管理
應(yīng)創(chuàng)建修改記錄，以提供每個(gè)請(qǐng)求或需要更改。變更管理程序必須考慮在授權(quán)變更之前，每項(xiàng)此類(lèi)變更的影響。這個(gè)變更的實(shí)施必須重復(fù)安全生命周期階段被改變了。結(jié)果變化的測(cè)試必須包括非回歸測(cè)試以及變化本身的測(cè)試。所有測(cè)試結(jié)果必須記錄。
退役必須指定系統(tǒng)退役的程序。這程序必須包括安全退役的要求系統(tǒng)和材料的安全移除或返還（如適用）。與調(diào)試一樣，可能會(huì)在分階段進(jìn)行。退役程序必須確保在保持功能安全的同時(shí)，開(kāi)發(fā)相應(yīng)的存在危險(xiǎn)。同樣，控制的物理環(huán)境當(dāng)設(shè)備需要運(yùn)行時(shí)，必須對(duì)其進(jìn)行維護(hù)。
退役程序必須解決以下事項(xiàng)：
?清除危險(xiǎn)的順序。
?允許消除安全之間相互作用的方法功能，同時(shí)保持剩余可能的功能安全危險(xiǎn)和未啟動(dòng)安全響應(yīng)。這必須包括系統(tǒng)之間的交互。
?返回模塊和材料的定義退役后道德處置的羅克韋爾自動(dòng)化。
變化歷史本附錄包含每個(gè)修訂版的新信息或更新信息本出版物。這些列表僅包含實(shí)質(zhì)性更新旨在反映所有變化。

Modification Records and Change Management
Modification records shall be created to give traceability of each requested or required change. The change management procedure must consider the impact of each such change before authorizing the change. The implementation of the change must repeat the safety lifecycle phases which are altered by the change. The test of the resultant changes must include nonregression testing as well as test of the change itself. All test results must be recorded. Decommissioning The procedure for decommissioning the system must be specified. This procedure must include the requirements for the safe decommissioning of the system and, where applicable, the safe removal or return of materials.As with commissioning, it is likely the decommissioning will be performed in a phased manner. The decommissioning procedure must make sure that a plan be developed that maintains the functional safety while the corresponding hazards are present. Similarly, the physical environment of the control equipment must be maintained while the equipment is required to function. The procedure for decommissioning must address the following items: ? The sequence in which the hazards are to be removed. ? Methods which permit the removal of interactions between safety functions while maintaining functional safety for the remaining possible hazards and without initiating safety responses. This must include the interaction between systems. ? A definition of the modules and materials which are to be returned to Rockwell Automation for ethical disposal following decommissioning.
History of Changes
This appendix contains the new or updated information for each revision of this publication. These lists include substantive updates only and are not intended to reflect all changes. Translated versions are not always available for each revision.The following terms and abbreviations are used throughout this manual. For definitions of terms not listed here, refer to the Allen-Bradley Industrial Automation Glossary, publication AG-7.1. A AADvance Workbench software A design, configuration, and maintenance software environment that enables the design of a multi-controller safety strategy as a single project, and then targets parts of the strategy for each controller. AADvance-Trusted SIS Workstation software A software suite for building process control projects for use with Trusted? Series 8000 controllers or AADvance? Series 9000 controllers. accuracy The degree of conformity of a measure to a standard or a true value. See also 'resolution'. achievable safe state A safe state that is achievable.Sometimes, a safe state cannot be achieved. An example is a non-recoverable fault such as a voting element with a shorted switch and no means to bypass the effect of the short.
