The high performance and freely programmable L-INX Automation Server LINX-212 and LINX-213 are used for control applications in hotel and building automation. They 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 built-in PLC functionality (IEC 61131-3) provides a high level of programming freedom. Programming is done with the L-LOGICAD programming tool. The programming tool is based on the IEC 61131-3 standard and offers the programming languages Function Block Diagram (FBD) and Structured Text (ST).

The L-LOGICAD programming tool allows online testing of the IEC61131-3 application over the building network. New IEC 61131-3 applications can be downloaded onto the device without interrupting the current program execution. Multiple IEC 61131-3 programs can be executed in parallel with different cycle times down to 10 ms.
Commissioning and data point definition is done by the L-INX Configurator. Defined Data points coming from different technologies (BACnet, Modbus, M-Bus) can be processed by the L-logiCAD programming tool.
Designed to report high volume of information from remote, LINX also includes an internal SCADA server over which it is possible to design multiple screens with different monitoring values and control any datapoint of the remote building.
