Multiple models available

Multiple models are available with varying device capacities for integrations that meet the intended application.

Linux® operating system

The SNE runs on Linux, which is a robust, widely-accepted, and readily-supporting operating system.

User interface

You use the Metasys UI to access system data in the network engines from any supported web browser device connected to the network, including remote users connected by Virtual Private Network (VPN).

Encrypted Communications

All SNE network engines have self-signed certificates that provide for encrypted communication. Optionally, you can deploy trusted certificates from the customer's IT department or from a Certificate Authority (CA).

FIPS 140-2 Level 1 Compliance using FIPS validated components

All SNEs that run Release 11.0 firmware or later include the FIPS 140-2 feature that provides FIPS compliance. The FIPS 140-2 standard is an information technology security approval program for cryptographic modules produced by private sector vendors who seek to have their products certified for use in government departments and regulated industries. For a site to be fully FIPS compliant and certified, you need to upgrade all network engines to Release 11.0, then install and license the FIPS 140-2 feature on the Metasys Server. Additionally at Release 11.0, the SNEs are FIPS 140-2 validated.

Memory

The SNE has 2 GB RAM and 16 GB Flash non-volatile memory. This memory provides capacity for further upgrades and a longer operational life.

Background file transfer

You can transfer files such as firmware upgrades, archive databases, and security databases from the SCT to the SNE while the engine remains operational, minimizing system disruptions.

Device security

Device integrity is ensured while the system is rebooting and during normal operation. Embedded technology provides trusted boot operation, firmware protection, secure storage, secure communications, and secure firmware updates complying with strong cyber security practices.

Smaller, modularized packaging

The smaller size of the SNE reduces the amount of space you need for mounting, and can potentially reduce the size and cost of control panels.

Diagnostic multi-color LEDs

The use of multi-color LEDs can decrease installation and troubleshooting time.

Removable terminal blocks

The use of removable terminal blocks facilitates ease in installation and servicing.

Support for different site directors

The SNE can act as a site director for small sites and also communicate as a child engine to a wide variety of site director types for medium and large sites, including the NAE85/LCS85 software engines and the ADS, ADX, and OAS series application servers. The ADS-Lite-A (Asia) and ADS-Lite-E (Europe) site directors are supported for select regions only.

Supervision of controller networks including Johnson Controls devices and third-party protocol devices

Supports connectivity to open network standards for complete flexibility in the selection of field devices. They include BACnet/IP, BACnet/SC, BACnet MS/TP, N2 Bus, LonWorks, Modbus TCP/IP, Modbus RTU, M-Bus, KNX, Zettler Fire Panel, Tyco C•CURE, victor, OPC Unified Architecture (UA), and other third-party protocols.

MQTT Integration Driver

The MQTT driver supports bidirectional communication between the SNE and a generic MQTT broker, providing an option to exchange Metasys data with popular IoT platforms and applications.

No battery

The SNE uses a supercapacitor, not a battery, to provide temporary power for data backups during shutdown due to AC power loss. This design is more environmentally friendly and saves the eventual cost of replacing the battery. When the supercapacitor is fully charged, the SNE can maintain the real time clock for up to 72 hours during AC power loss.

BACnet/SC

BACnet Secure Connect (BACnet/SC) is a recent update to the BACnet interoperability standard aimed at improving cybersecurity and network infrastructure integrity. BACnet/SC identifies a secure, encrypted datalink layer specifically designed to meet the requirements, policies, and constraints of IP networking infrastructures.
