Modbus Connect vs Modbus TCP FieldKit

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

Modbus TCP FieldKit puts a professional Modbus TCP toolkit in your pocket. Commission equipment in the field, validate setups in the lab, or troubleshoot home automation — all from your iPhone. • Connect to any Modbus TCP device — read coils and registers, monitor data blocks in real time • Save device profiles for one-tap reconnection to frequently used endpoints • Write with confidence — every write operation requires your explicit confirmation • Built-in foreground simulator — run editable coils and holding registers for testing • Track active connections and review bounded local logs kept on your device • All data stays local — logs and exports are sanitized by default Requires Local Network access for device communication. Default server port is 1502. Background server operation and port 502 support pending device validation.
