LIOB-590 Building Automation Controller: 20 Universal I/O (IO)

The LIOB-590 I/O controller is equipped with two Ethernet ports and an integrated Ethernet switch. This allows a daisy-chain line topology of up to 20 devices, reducing network installation costs. Devices with dual Ethernet ports also allow for a redundant Ethernet installation (ring topology), which increases reliability. Technology 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 SSL encrypted 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 (alarms, scheduling, and trending), store custom graphic pages for visualization in LWEB-802/803, and can be seamlessly integrated into 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 the system to connect to almost any cloud service, either to upload historical data to analysis services, send alarm messages to alarm processing services, or manage parts of the control system via a cloud service (e.g., scheduling based on web calendars or booking systems). Internet information, such as weather data, can also be processed for forecast-based control. Finally, the JavaScript kernel also enables the implementation of serial protocols for non-standard equipment in primary plant control.

### Local Operation and Override

All L-IOB I/O controllers are equipped with an LCD display (128x64) with backlighting and a jog dial for manual local operation and override. Device and data point information is displayed in text form and via graphic symbols.
