Run the actual screens
HQControl receives exported screen files, publishes them into the runtime directory, configures menu entry points, opens popup templates, and loads these pages in the runtime platform.

Start Here: What HQControl can do for a site
You do not need to understand every menu first. HQControl puts screens, device data, alarms, trends, access control, licensing, and external interfaces into one long-running runtime.Connect devices and tags
Devices define PLCs or data sources. Tags define names, addresses, data types, scan rates, and grouping fields. Siemens S7 supports absolute addresses through S7 TCP and symbolic addresses through OPC UA. Tag Diagnostics confirms live values and quality before screens, alarms, trends, or APIs rely on them.
Record alarms and trends
HQControl records alarms, recoveries, events, and historical trend points. Large histories are viewed by time range, filters, lazy loading, and drill-down instead of loading everything at once.
Manage access, licensing, and audit trails
Administrators, engineers, operators, and guests can have different capabilities. Writes, control actions, configuration pages, and licensing are separated, while event records help trace changes.
Expose data to other systems
IO State API is for reading live values, WebSocket is for subscribing to changes, and Integration Script handles HTTP, MQTT, SQL, scheduled tasks, and site-specific automation.
Support cloud, federation, and redundancy
The same runtime model works on Windows, Linux, and cloud servers. Federation organizes sites; redundancy decides which node actively polls and writes each device.
From field devices to runtime screens: collection, storage, alarms and trends, access and licensing, and third-party APIs all live inside HQControl, with multi-site federation and hot standby keeping it running.
