LIOB-593 I/O Controllers are compact, programmable, IP-enabled BACnet Building Controllers (B-BC) with physical inputs and outputs and integrated graphical visualization.

Communication

LIOB-593 I/O Controllers are equipped with two Ethernet ports, including an integrated Ethernet switch. This allows creating a daisy-chain line topology of up to 20 devices, reducing network installation costs. Devices with dual Ethernet ports also allow configuring a redundant Ethernet installation (ring topology), which increases reliability. The redundant Ethernet topology is enabled by the Rapid Spanning Tree Protocol (RSTP), supported by most managed switches. Technological data points are automatically exposed as OPC tags for higher-level OPC client applications or for the L-WEB system via the integrated OPC server providing encrypted SSL web services (OPC XML-DA) or UA Secure Conversation (OPC UA). L-IOB I/O controllers also 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 perfectly integrated into the LWEB-900 building management system. L-IOB 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, whether for uploading historical data to analysis services, for telemetry via MQTT, for sending alarm messages to alarm processing services, or for managing parts of the control system via a cloud service (e.g., scheduling based on web calendars or booking systems). It is also possible to process Internet information, such as weather data, for forecast-based control. Finally, the JavaScript kernel also allows implementing serial protocols for non-standard equipment in primary plant control.

Local Operation and Override

All L-IOB I/O controllers feature 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.
