LIOB-586 I/O controllers are compact, programmable, IP-enabled automation stations for LonMark systems and BACnet/IP networks with physical inputs and outputs and integrated graphical display.

Communication

LIOB-586 I/O controllers are equipped with two Ethernet ports, including an integrated Ethernet switch. This enables a daisy-chain line topology of up to 20 devices, reducing network installation costs. Devices with dual Ethernet ports also enable the creation 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 for the L-WEB system via the integrated OPC server that provides SSL encrypted web services (OPC XML-DA) or UA Secure Conversation (OPC UA). L-IOB I/O controllers also enable data exchange over global connections (network-wide data exchange), offer AST™ functions (alarming, scheduling, and trending), store custom graphic pages for display in LWEB-802/ 803, and can be seamlessly integrated into the LWEB-900 building management system. LIOB-586/587/588/589 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 be connected to almost any cloud service, either to upload historical data to analytics services, to send alarm messages to alarm processing services, or to manage parts of the control system via a cloud service (e.g., web calendar-based scheduling or reservation systems). Internet information, such as weather data, can also be processed for forecast-based control. Finally, the JavaScript kernel also allows the implementation of serial protocols for nonstandard equipment in primary plant control.

Local operation and overrides

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. On the front panel of the LIOB-586 /LIOB-587, the six relay outputs can be overridden by 3-way switches.

Power measurement

External meters can be integrated via M-Bus or Modbus. LIOB-586/587/588/589 I/O controllers perfectly meet energy management and energy reporting applications. The LIOB-587 model includes integrated power measurement.
