The Metasys SNE series network engines and SNC series network control engines are Ethernet-based, supervisory controllers that connect Building Automation System (BAS) networks to IP networks. The NAE85 is a software-only network engine that runs on a Windows Server.
The NAE85, SNE and SNC perform a key role in the Metasys system architecture. They provide network management and system-wide control coordination over one or more networks of equipment controllers, including the following devices:
- CG series general purpose equipment controllers
- CV series VAV box controllers
- FEC and FAC series field equipment controllers
- VMA series VAV box controllers
- TEC series terminal equipment controllers
- LN series equipment controllers
- Third-party equipment controllers
These devices monitor and control networks of field-level building automation devices, including HVAC equipment, lighting, security, and fire safety equipment.
NAE85s/SNEs/SNCs provide building control scheduling, alarm and event management, energy management, data exchange, historical data storage and management, and custom control logic. Network engines include an embedded user interface for system navigation and operation using web browser connections. Network engines use password protection, permission access control, and IT security best practices to secure them from unauthorized access.
In addition to providing supervisory control capabilities, the SNC series also feature onboard input and output interfaces (I/O) and direct digital control capabilities of a controller. The SNE series succeeds the NAE series, and the SNC series succeeds the NCE series. The software-only NAE85 engine provides many of the same functions and capabilities as an SNE, but with much higher point capacities, facilitating customers who need to integrate large numbers of IP devices into their Metasys network. These controllers allow for the further expansion and enhancement of Metasys supervisory control capabilities.
SNE Series
- SNE2200x-0 succeeds the NAE55 series network engines.
- SNE1100x-0 succeeds the NAE45 series network engines.
- SNE1050x-0 succeeds the NAE35 series network engines.
- SNE110Lx-0 succeeds the NAE45-Lite series of network engines, and functions with the ADS-Lite-A server that is available in select regions.
SNC Series
SNCs succeed the NCE25 and NIE29 series network control engines.
