LIOB-590 I/O Controller

LIOB‑590 I/O Controllers are IP-enabled, compact, programmable automation stations for LonMark Systems, BACnet/IP and BACnet/SC networks with bidirectional I/Os configurable as either input or output and integrated graphical visualization.

Communication

The LIOB‑590 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 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 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. LIOB‑590 I/O Controllers implement the BACnet Building Controller (B-BC) profile and are BTL certified.

IoT Integration

The IoT function (Node.js) allows connecting the system to almost any cloud service, either for uploading historical data to analytics services, delivering alarm messages to alarm processing services or operating parts of the control system over a cloud service (e.g., scheduling based on Web calendars or booking systems). Processing Internet information such as weather data in forecast-based control is also possible. Finally, the JavaScript kernel also allows implementing serial protocols to non-standard equipment in primary plant control.

Local Operation and Override

All L‑IOB I/O Controllers are equipped with an LCD display (128×64) 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.
