Produce System Documentation The system documentation shall be produced as required and shall be reviewed and approved by a second engineer. Figure 2, titled 'l&C Design Process" shows the typical output documents produced by Pl&CS, as well as the inputs that are required. The processes that produce the outputs given the inputs compose the Pl&CS Transformation Matrix. These processes consist of dynamic tasks and differ for the various outputs produced. Figure 3, titled "Pl&CS Information Transformation Matrix' j further relates the information that is required as inputs to produce the Pl&CS outputs. The output documentation normally includes the following: I&C Architecture Diagram (see Appendix C) Process Block Diagrams (or equivalent) (see Appendix C) Equipment (Instrument) Lists Logic Diagrams (see Appendix C) Design Specifications I&C Databases Standard Safety Analysis Report input O mmionei Page 6 of 20 ,,,,. i.oona erm o em.
