Custom Web Control

About PLC Network Monitor

The PLC Network Monitor is a professional Custom Web Control designed for high-performance industrial SCADA and HMI environments. It provides a centralized dashboard for monitoring the network connectivity and operational status of multiple controllers simultaneously. By visualizing critical states such as RUN, STOP, and DISCONNECTED, it ensures operators have immediate visibility into the health of the automation layer across WinCC Unified and WinCC V8 platforms.

Key Features

• Dynamic Fleet Management: Add new controllers in real-time using the IPv4 input interface, triggering the PlcAdded event for seamless integration with HMI logic.
• Automated Diagnostics: Utilize the autoPollEnabled feature and autoPollIntervalMs to maintain a continuous background refresh of all device states without manual intervention.
• Granular Control: Perform individual device testing via the diagnosePlc method or execute a full system sweep using the diagnoseAll function to validate the entire network fabric.
• State Visualization: Integrated status chips provide instant counts for total, running, and stopped devices using the totalLabel, runLabel, and stopLabel properties.

Customization

Engineers can fully brand the interface using the backgroundColor property and localize all UI elements via properties like addPlcButtonText, checkAllButtonText, and diagnoseButtonText. The control also features robust input validation with a customizable invalidIpMessage to prevent configuration errors during runtime.

Use Cases

This control is ideal for large-scale infrastructure monitoring, multi-line manufacturing facilities, and distributed control systems where real-time network topology awareness is critical for minimizing downtime.

Compatibility

Fully compatible with WinCC Unified (TIA Portal) and WinCC V8. The control supports bidirectional data flow through standard HMI tags and JavaScript methods.
