Modbus Connect is an HMI app for monitoring and controlling Modbus TCP devices on a local network from iPhone. With Modbus Connect, you can configure devices, create tags, and build a visual dashboard with widgets for control and live variable display. Main features: - Connection to Modbus TCP devices on a local network - Configuration of coil, input, holding register, and input register tags - Custom visual dashboard - Control and indicator widgets - Read bool, 16-bit unsigned, and 32-bit float values - Buttons, push buttons, lamps, fan, displays, level, and gauge widgets - Built-in DEMO mode for testing without real hardware Intended use: - Integration testing - Process variable visualization - Mobile HMI interfaces - Basic field validation of signals and tags Notes: - The app works with Modbus TCP devices - Local Network access is required to connect to the configured device - The user is responsible for validating system configuration and behavior before use in real environments
