Connections (Wires)

Connections are created by clicking the output port of a block (right side), then clicking the input port of another block (left side). Wires are rendered as Bezier curves.

• Input ports — on the left side of the block
• Output ports — on the right side of the block
• Delete wire — select + Delete

Multi-Page Projects

A project can contain a main page and any number of additional pages:

• + button in the header — add a new page
• Tabs — switch between pages
• Each page has its own set of blocks and shapes

Popups

Popups are pages that open as modal windows in Runtime when an equipment element is clicked. They are used to display detailed parameters for a specific node.

Runtime Environment

Toggle: Runtime button in the header.

Trends & Historian

The Trend block supports 3 channels with configurable colors and names. Real-time buffer — 200 data points.

Viewing Historian Data

Alarm Notifications

The Alarm Sound block generates audio via the WebAudio API:

OPC UA

OPC UA (IEC 62541) — universal data access. The Gateway starts a server at opc.tcp://hostname:4840.

Configuration: SCADA → Settings → OPC UA → endpoint, port, security mode.

Modbus TCP

Standard industrial protocol. Gateway: port 502 (or 1502 if in use). Supported function codes: FC 3 (Read Holding Registers), FC 4 (Read Input Registers), FC 6 (Write Single Register), FC 16 (Write Multiple Registers).

OPC DA / InTouch / WinCC

Classic OPC DA via DCOM. Windows required. Supports Kepware, Wonderware InTouch (Wonderware.InTouch.OPCServer), Siemens WinCC (OPCServer.WinCC).

SCADA Gateway

The Gateway is the server-side component of the system. It runs 12 parallel protocol processing threads.

Troubleshooting

Security

• Trial mode: 2-hour operation with anti-tamper protection
• Integrity: SHA256 hash of JSX code, verified on load
• Base64: source code is encoded inside the HTML file
• Editor protection: login/password in settings
• Roles: Operator / Engineer / Admin
• Passwords: SHA256 hash stored in SQLite

Licensing

Built-in licensing system with no activation servers required. Each build contains:

• Build ID — 16-character SHA256 hash
• License Key — 4 groups of 8 characters (MD5)
• Integrity Hash — SHA256 checksum
