Modbus TCP FieldKit vs Modbus TCP Tools

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.
