Management of Modifications is essential and sensitive to Functional Safety –

especially over time. Audits and revisions of procedures for management of

modifications are therefore vital.

Although this requirement mostly is interpreted to specifically address the operation

phase, the other phases should also be covered.

Configuration Management

Configuration Management aims to manage and maintain traceability of devices

through the lifecycle of the SIS.

The user of the system shall establish a practice to maintain an overview of software

and hardware versions of the installed equipment, as well as versions of application

software and libraries.

If the system is configured as a combined BPCS and SIS, the configuration

management procedures shall identify the different requirements for handling

subsystems of different SIL.

Procedures shall be established for preventing unauthorized items from entering

service.
