Industrial HMI Telemetry on Android
Engineered for automation technicians and commissioning engineers. Real-time machine monitoring, setpoint control, Control Word bit extraction, and fail-safe watchdog supervision with zero cloud dependencies.
Built for Real Industrial Environments
No compromises. Direct socket communication engineered for factory floors, marine subsea units, and remote SCADA sites.
OPC-UA (IEC 62541)
Connect with Anonymous or User/Password authentication across None and Basic256Sha256 encrypted profiles with hardware KeyStore X.509 certificates.
Modbus TCP / IP (Port 502)
Full support for Coils (0x), Discrete Inputs (1x), Input Registers (3x), and Holding Registers (4x). Supports Big-Endian Floats, Word-Swapped Floats, and 32-bit Integers.
Control Word Bit Extraction
Extract single bits from packed 16-bit words or registers into dedicated momentary or toggle buttons with thread-safe Read-Modify-Write (RMW) mutexes.
Fail-Safe Watchdog Supervisor
Sends periodic heartbeat pulses (100ms - 5s) to target boolean/integer registers. Watchdogs remain disarmed by default and disarm automatically upon disconnect.
Offline Design Studio
Build, arrange, and pre-map dashboard widgets without a live PLC connection. Export and import entire machine profiles as standalone .json files.
100% Private & Cloud-Free
Zero third-party telemetry, ads, or analytics tracking. All credentials and network packets remain strictly between your device and your machine.
Flexible Tag Mapping Notation
OpcVue supports standard industrial addressing formats out of the box.

Modbus | Float32 (Slave 2) | Slave ID 2 Unit Override on Holding Register 40001 |
ns=2;s=Drive.Speed_RPM |
OPC-UA | Double / Float | OPC-UA String Node Identifier |
ns=1;i=1004 |
OPC-UA | UInt16 / Packed | OPC-UA Numeric Node Identifier with Bit Extraction |
Industrial Grade Security Architecture
Engineered for defense-in-depth isolation in critical infrastructure.
Direct TCP Socket Architecture
All network traffic travels directly between your device and the configured PLC endpoint over LAN, Wi-Fi, or VPN.
Hardware KeyStore Encryption
Project passwords, security tokens, and X.509 private keys are encrypted using AES-256 GCM backed by the Android Hardware KeyStore.
Zero Cloud Data Collection
No user accounts required. No analytics scripts. No telemetry logging to third-party databases.
Fail-Safe Disarm on Timeout
Active watchdogs and momentary write buttons instantly disarm and release upon socket drops or application backgrounding.
