See Table 1 for IP address assignment rules in the Metasys system. In this table, the term Site Director is introduced. The Site Director is the device designated to maintain the site information by holding the Site object, which contains information about the logical organization of data about your facility, user password administrative information, and overall time and date. This function resides in an engine or in a Metasys Server on large installations. Although an engine can be a Site Director, if the site has a Metasys Server, then a Metasys Server must be the Site Director. The Site Director provides a uniform point of entry and supports functions such as user login, user administration, time synchronization, and traffic management.
