OpcVue is a native HMI and SCADA client for Android, specifically engineered for engineers, production line technicians, and automation developers. This application provides direct access to industrial PLCs, PUs, and IoT services via OPC-UA and Modbus TCP protocols. It offers a clear and convenient interface for monitoring equipment status directly on smartphones or tablets, eliminating the need for expensive intermediaries for data transmission.
The app is ideal for troubleshooting on the factory floor, verifying input/output signals during commissioning, or conducting remote monitoring of industrial equipment. Key features of OpcVue include support for multiple protocols simultaneously. Users can connect to OPC-UA servers (IEC 62541 standard) and Modbus TCP devices.
The interface provides a set of real-time widgets such as circular and bar indicators, trend graphs, setpoint sliders, switches, takt buttons, and alarm indicators. A convenient OPC-UA node browser allows you to view the address space tree with a live search function. Full Modbus address support covers holding registers, input registers, coils, and discrete inputs with slave identifier routing.
The software supports various data types, including Boolean, Int16, Int32, UInt16, UInt32, and IEEE 754 Float32, with configurable byte ordering. For secure critical operations, blocking mechanisms with hold and confirmation are included, along with watchdog status indicators.
