The Metasys® SNE Series of network engines and SNC Series of network control engines are Ethernetbased, supervisory engines that connect Building
Automation System (BAS) networks to IP networks. The SNE Series of network engines succeed the NAE Series of network engines, and the SNC Series of
network control engines succeed the NCE Series of network control engines. This allows for the further expansion and enhancement of Metasys supervisory
control capabilities. The SNE and SNC perform a key role in the Metasys system architecture. These devices monitor and control networks of field-level building automation devices, including HVAC equipment, lighting, security, and fire safety equipment. They provide network management and system-wide control
coordination over one or more networks of equipment controllers, including the following Metasys equipment controllers:
• CGM series general purpose equipment controllers
• CVM 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.
