The following features and benefits are applicable to SNEs and SNCs:
- Multiple models available
- Multiple models, including Buy American versions, are available with varying device capacities for integrations and integral control I/O provide flexibility to select the appropriate model for the intended application.
- Linux® operating system
- Provides a robust, widely-accepted, and readily-supported operating system.
- User interface
- You can use the new primary user interface Metasys UI, or the Site Management Portal (SMP) UI, to access system data in the network engines from any supported web browser device connected to the network.
- Encrypted communications
- All SNE and SNC 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).
- Supports background file transfer
- You can transfer files such as firmware upgrades, archive databases, or security transfers from the System Configuration Tool (SCT) to the SNE or SNC while it remains operational, minimizing system disruptions.
- Device security
- Ensures device integrity 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 size of the SNE is smaller than the NAE. This 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 installation and servicing.
- Support for different site directors
- The SNE and SNC can communicate with a wide variety of site director types, including the NAE85/LCS85 software engines and the Application and Data Server (ADS), Extended Application and Data Server (ADX), and Open Application Server (OAS). 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, MQTT, and other third-party protocols
- No battery
- The SNE and SNC use 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 and SNC can maintain the real time clock for up to 72 hours during AC power loss.
- FIPS 140-2 Level 1 Compliance using FIPS validated components
- FIPS 140-2 is a U.S. government cybersecurity standard used to approve cryptographic modules and algorithms used for encryption. Assures end customers that Metasys uses strong cybersecurity techniques to prevent unauthorized access to systems and data.
- OPC UA Integration Driver
- OPC Unified Architecture (OPC UA) is a machine-to-machine communication protocol popular with industrial automation and process control type devices. The OPC UA integration driver provides the Metasys system with the ability to monitor, command, schedule, alarm, trend, interlock, and share data with OPC UA devices, including the new Johnson Controls PLC offering.
- MQTT Integration Driver
- The MQTT driver supports bidirectional communication between the SNE/SNC and a generic MQTT broker, providing an option to exchange Metasys data with popular IoT platforms and applications.
- Updated BACnet compliance
- Network Engines are enhanced to support BACnet Protocol Revision 18. Assures end customers of compliance to BACnet standard to support interoperability with third-party BACnet devices.
Additional SNC features and benefits
The following features and benefits are specific to the SNC:
- Onboard inputs and outputs
-
Provides direct equipment-level control including central plant and large air-handler applications combined with enterprise-level IP network connectivity. The SNC2515x has 25 inputs and 15 outputs, and the SNC1612x has 16 inputs and 12 outputs.
- Expandable I/O point capacity, NS sensor connectivity, and Variable Frequency Drive (VFD) control on SA Bus
- You can connect to multiple I/O Expansion Modules, NS Series Network Sensors, and VFD connections to the SA Bus, which greatly expands control capabilities.
- Generic SA Bus object (SNC only)
- A more nimble method for supporting the integration of approved BACnet MS/TP edge devices on the SA Bus. Provides system designers with more SA Bus device options to cost-effectively meet controls project requirements.
- SA Bus provisioning expanded to support XPM and NS8000 SA Bus devices (SNC only)
- SA Bus devices (for example, XPMs and NS8000s) can be updated through the host controller. Saves field technicians time by streamlining upgrade workflows.
- Optional onboard or remote user interface
- Certain SNC models feature on onboard, 2.4 in. (61 mm), 320
x 240 resolution display and associated keypad providing local user
interface capabilities. Alternatively, you can connect an optional display
with keypad, product code M4
-DLK0350-0, to the SNC and mount it
remotely. These user interfaces provide field technicians with the ability
to quickly, clearly, and conveniently monitor equipment status, view alarms,
see trends, issue overrides, and change setpoints and parameters. Note: Only the SNC models that end in H feature the built-in display. If you downgrade an SNC below version 11.0, the display is not supported.
