LIOB-48x I/O Controllers are IP-enabled, compact, programmable automation stations for LonMark Systems with physical inputs and outputs and integrated graphical visualization.
LonMark IP-852 Channel over Ethernet
The LIOB‑48x I/O Controller is equipped with two Ethernet ports, including a builtin 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 topol‑ ogy), 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 Controllers further allow data exchange over global connections (network-wide data exchange), offer AST™ functions (Alarming, Scheduling, and Trending), store custom graphic pages for visualization in LWEB‑802/803, and can be seamlessly integrated in the LWEB‑900 Building Management System.
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 infor‑ mation is displayed in text form and via graphical symbols.
