To facilitate communication, it is necessary to establish formal rules for what is, and is not, represented on each type of Control and Information System Diagram. Based on our experience to date, we propose the following presentation rules:

The Control and Information Architecture Diagram should include the following:

The CIAD is developed during the Conceptual Engineering Phase, in parallel with the PFD (or MFD).

The Control and Information System Network Diagram should include the following:

The CIND is developed during the Preliminary Engineering Phase, in parallel with the PFD (or MFD).
