LWEB-900

LWEB-900 is LOYTEC Integrated Building Management System software, named on the product page as LWEB-900 Building Management Software. One ownership correction matters: LOYTEC is not a Schneider Electric business. LOYTEC own page states that LOYTEC is today a brand of Delta Electronics, operating within the Intelligent Building Technologies business unit. The company remains based in Vienna, Austria.

It is unambiguously software, and the most conventional supervisory software in this group. The architecture is client-server on Windows: one LWEB-900 server plus dedicated-application or browser clients, where the server stores parameters, historic data, access rights and device configurations in an SQL database and exchanges real-time data with LOYTEC devices over web services independently of the field bus. Supported server operating systems are Windows 10 and 11 and Windows Server 2012 through 2022, with a minimum of a 2 GHz CPU, 4 GB RAM and 50 GB of disk. Because the real-time exchange uses web services, clients work across firewalls and NAT routers, which is a practical advantage for remote sites.

The feature list is broad and specific. Graphical schematic views use SVG and raster graphics and need no HTML or Java skills. Alarming consolidates multiple sources with acknowledge and disable, email notification and escalation if an alarm is not acknowledged in time. Scheduling is hierarchical and can run on field devices or on the server with a calendar-style interface. Trending reads data periodically into the database with tables, charts and CSV export, and can also receive emailed trend data from devices that are not IP reachable. An event log records alarms, logins, parameter changes, configuration changes and system messages with filtering. A parameter matrix view allows bulk parameter setting across many devices at once. Global connections configure device-to-device IP data exchange. The device manager handles status, individual and group firmware updates, automatic backup and restore onto a replacement device. Reporting outputs PDF, Excel and Word from trend logs on a schedule, on an event or on demand, emailable, with energy consumption reporting given as an example. Other modules include a BACnet Operator Workstation at B-OWS v2.0, Watch View, AKS identification key schemas, ONVIF camera integration, Multi-Site access to several servers from one client, Node.js scripting with an integrated Node-RED runtime, and OpenVPN-based VPN configuration as a separately licensed option.

Protocol coverage is genuinely multi-vendor at the field bus level: the product page lists CEA-709, which is the LonWorks standard, BACnet, DALI, M-Bus, Modbus and KNX. Note what is absent: MQTT is not mentioned and OPC UA is not confirmed for LWEB-900, since the page describes OPC XML-DA and SOAP and XML web services and OPC UA appears only as site navigation. For buyers comparing against newer IoT-oriented platforms, that dates the connectivity story.

Licensing is published in structure: a base licence for 10 devices, add-ons in 10 device blocks or an unlimited-device variant, with the standard licence including five LWEB-900 clients and twenty lighter clients, and Multi-Site, VPN base and VPN maintenance as separate add-ons. A 30 day demo licence with 10 devices lowers evaluation cost. Usefully, LOYTEC L-IP routers and L-IOB modules connected to L-INX automation servers do not count against the device licence.

Who it fits. Sites where LOYTEC L-INX, L-IOB and L-IP field hardware is already specified, which is where the device manager, global connections and configuration restore features pay off: group firmware updates and restore onto a replacement device are genuine operational savings. It also fits European estates with mixed field buses, since CEA-709, BACnet, DALI, M-Bus, Modbus and KNX are supported from one server, and reporting-heavy clients, given the scheduled and event-driven PDF, Excel and Word output. The 30 day 10 device demo licence makes it one of the few products in this category you can evaluate cheaply.

Who it does not fit. Buyers wanting a vendor-hosted SaaS, since this is Windows server software on premises with no hosted offering described. Buyers needing MQTT or confirmed OPC UA support. Buyers who want self-service documentation, since the LOYTEC download and documentation area is login gated. And buyers wanting a genuinely vendor-neutral head-end, because the page frames LWEB-900 as configuring and operating LOYTEC building automation systems and the device licence is counted in LOYTEC devices.

Typical use. European integrator-delivered buildings and campuses on LOYTEC hardware, scaling from a 10 device base licence to an unlimited licence with Multi-Site for portfolio access. One roadmap consideration worth naming: LOYTEC now sits inside Delta Electronics Intelligent Building Technologies unit alongside Delta own building automation portfolio, which is a consolidation risk to weigh.
