For each Metasys system network site, a single network engine or a Metasys server (ADS, ADX, or OAS) is designated as the Site Director. The Site Director provides a single point of access to the site and all of the web-enabled devices on the site. The Site Director supports functions such as user login, user administration, user views, time synchronization, and data traffic management.

On larger building control networks with one or more Metasys servers, a Metasys server is designated as the Site Director. On small network sites without a Metasys server, you must designate one of the SNEs as the Site Director.

By default, an SNE is designated as a Site Director when its firmware in loaded in the factory. You must demote any SNE that is not the designated Site Director on a site. See Designating an SNE as a child of a Site Director for more information.

If a Metasys server is on a site, an SNE cannot be the Site Director. You must demote the SNE to be a child of a Metasys server. See Designating an SNE as a child of a Site Director for more information.

Note: The SNE110Lx model cannot be a Site Director to other engines. The SNE110Lx can only be a child device of an ADS-Lite-A. You must demote the SNE110Lx to be a child of an ADS-Lite. See Designating an SNE as a child of a Site Director for more information.

The following table lists the supervisory rights of each network engine model when it serves as a Site Director.

Table 1. Supervisory Rights

Note: If you attempt to add an SNE to a site and the new SNE exceeds the supervisory device limit for the Site Director, the Site Director does not accept the additional device. The Site Director records an error message in the Site Director Audit Viewer each time you attempt to add a new device that exceeds the device limit.
