The LIOB‑586/588/589 I/O Controllers are IP-enabled, compact, programmable automation stations for LonMark Systems and BACnet/ IP networks with physical inputs and outputs and integrated graphical visualization.

The LIOB‑588 I/O Controller 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.

Technology data points are automatically exposed as OPC tags for higher level OPC client applications or L‑WEB system via the integrated OPC server providing SSL encrypted web services (OPC XML‑DA) or UA Secure Conversation (OPC UA). The L‑IOB I/O Controller further allows data exchange over global connections (network-wide data exchange), offers AST™ functions (Alarming, Scheduling, and Trending), stores custom graphic pages for visualization in LWEB‑802/ 803, and can be seamlessly integrated in the LWEB‑900 Building Management System. The LIOB‑588 I/O Controller implements the BACnet Building Controller (B-BC) profile and is BTL certified.

Local Operation and Override: All L‑IOB I/O Controllers are equipped with an LCD display (128x64) with backlight and jog dial for manual local operation and override. Device and data point information is displayed in text form and via graphical symbols. On the LIOB‑588 front panel the six relay outputs can be overridden via 3-way switches.

Power Measurement: External meters can be integrated via M‑Bus or Modbus. The LIOB‑588 I/O Controller perfectly meets energy management and energy reporting applications.
