You can use this Interface Control Document template to describe the relationship between system components in terms of data items and messages passed, protocols observed and timing and sequencing of events. Interface Control Documents (ICD) are a key element of systems engineering as they define and control the interface(s) of a system, and thereby bound its requirements.
