LINX-153/154 Automation Server
The L‑INX Automation Servers LINX‑153 and LINX‑154 are powerful, programmable automation stations, which can be programmed by L‑STUDIO. The L‑INX Automation Servers can host user specific graphical pages and can integrate physical I/ Os through L‑IOB I/ O Modules via LIOB‑Connect, LIOB‑FT, or LIOB‑IP. The LINX‑154 can only be extended by LIOB‑IP. Local operation and override is provided by the built-in jog dial and the backlit display (128x64 pixels). Device and data point information is shown on the display via symbols and in text format.
The powerful Automation Servers provide connectivity functions to concurrently integrate CEA‑709 (LonMark Systems), BACnet, KNX, Modbus, and M‑Bus subsystems. LonMark Systems can be integrated via IP‑852 (Ethernet/ IP) or TP/ FT‑10. BACnet integration is supported through BACnet/ IP (Ethernet/ IP) or BACnet MS/ TP (RS‑485). LINX‑153 Automation Servers feature an integrated Remote Network Interface (RNI) to access the TP/ FT‑10 channel on the device via Ethernet/ IP. LINX‑153 Automation Servers feature two built-in routers, one IP‑852 router and one BACnet/ IP to MS/ TP router including BBMD as well as Slave-Proxy functionality providing the complete feature set of the corresponding L-IP devices.
The LINX‑153 and LINX‑154 implement the BACnet Building Controller (B-BC) profile and are BTL certified. In addition, the LINX‑15x provide connectivity to KNXnet/ IP (only LINX‑153) and Modbus TCP via Ethernet/ IP and to Modbus RTU via RS‑485. M‑Bus and KNX TP1 (only for LINX‑153) device integration needs optional interface modules.
The gateway functionality allows data communication between all communication technologies available on the device. Different technology data points are mapped through Local Connections on the device. The mapping of different technology data points on distributed devices is supported by Global Connections. L‑INX Automation Servers also support Smart Auto-Connect™ – the automatic generation of connections to substantially reduce engineering efforts and cost. All technology data points are automatically created as OPC XML‑DA and OPC UA data points.
Each L‑INX Automation Server is equipped with two Ethernet ports. It can either be configured to use the internal switch to interconnect the two ports or every port is configured to work in a separate IP network.
When the Ethernet ports are configured for two separate IP networks, one port can be connected for instance to a WAN (Wide Area Network) with enabled network security (HTTPS) while the second port can be configured to be connected to an insecure network (LAN) where the standard building automation protocols like BACnet/ IP, LON/ IP, or Modbus TCP are present. These devices also feature firewall functionality of course to isolate particular protocols or services between the ports.
Using the internal switch, a daisy chained line topology of up to 20 devices can be built, which reduces costs for network installation. The IP switch also allows the setup of a redundant Ethernet installation (ring topology), which increases reliability. The redundant Ethernet topology is enabled by the Rapid Spanning Tree Protocol (RSTP), which is supported by most managed switches.
The L‑INX devices provide fully featured AST™ functionality (Alarming, Scheduling, and Trending) and can be integrated perfectly into the L‑WEB System.
