An interface specification should be developed between the SPCS vendor, DCS vendor and the “Operating Company” prior to the implementation of MDIS. The interface specification should provide the required fidelity to ensure all project specific requirements have been met. During the development of this specification it is recommended to review the project check list in Section B.8.

The SPCS vendor shall maintain revision control of the UANodeSet file that is being utilised by the project.

External interfaces (i.e. historians, condition monitoring systems, etc.) should also be specified however are outside the scope of this specification.
