LIOB‑550

The LIOB-55x Modules communicate over Ethernet/ IP in the BACnet/ IP network. They adhere to the BACnet Building Controller Profile (B-BC) and either expose their I/ O data points through BACnet server objects or actively fetch them from a BACnet server via BACnet client maps. According to the B-BC profile, the LIOB-55x Modules support BACnet alarming, scheduling, and trending. They are BTL tested and certified. BACnet/ IP over Ethernet The LIOB-55x I/ O Modules are 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 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 LIOB-55x Modules are equipped with a web interface to query the device status and display or change each data point of the module. In addition to the BACnet object interface, the I/ O data points are exposed by the integrated OPC server providing SSL encrypted web services (OPC XML-DA) or UA Secure Conversation (OPC UA). The local display can be accessed via VNC. LIOB‑IP Mode The LIOB-55x Modules can be switched to LIOB-IP mode using manual local operation. In LIOB-IP mode, the LIOB-55x Modules extend L-INX Automation Servers, L-ROC Room Controllers, L-IOB I/ O Controllers, and LIOB-AIR I/O Controllers with physical inputs and outputs via plug and play. Local Operation and Override All L-IOB I/ O Modules are equipped with an LCD display (128x64) with backlight and jog dial for manual local operation. Device and data point information is displayed in text form and via graphical symbols.
