LINX-220/221 Automation Server BACnet
The L-INX Automation Servers LINX-220 and LINX-221 are powerful, programmable automation stations. They 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. 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 BACnet, KNX, Modbus, and M-Bus subsystems. BACnet integration is supported through BACnet/IP (Ethernet/IP) or BACnet MS/TP (RS-485). LINX‑221 Automation Servers feature a built-in BACnet/IP to MS/TP router including BBMD as well as Slave-Proxy functionality providing the complete feature set of the corresponding L-IP device. Both LINX‑220 and LINX‑221 implement the BACnet Building Controller (B-BC) profile and are BTL tested and WSPcert certified. In addition, the L-INX Automation Servers provide connectivity to KNXnet/IP and Modbus TCP via Ethernet/IP and to Modbus RTU via RS-485. M-Bus and KNX TP1 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 including a built-in Ethernet switch. This allows for building a daisy chained line topology of up to 20 devices, which reduces costs for network installation. Dual Ethernet port devices also allow 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.
