- 📦Modbus TCP FieldKit updated to version 1.2.2New in 1.2.2:
• When a device answers with a Modbus exception, you stay connected. Read, Write and Disconnect keep working on the same connection.
• When a connection fails, the app names the cause it can tell: a closed port, a device name it cannot find, an address outside your network, or no Wi-Fi or Ethernet.
• If the app cannot tell whether a write reached the device, the result says Write result unknown and asks you to read the value back before you write again.
• Live monitoring over Modbus TCP keeps polling after one missed reply and stops after three in a row.… more - 📈Modbus TCP FieldKit entered the top 100Top Paid · Utilities · AU

- 📦Modbus TCP FieldKit updated to version 1.2.1New in 1.2.1:
• Before a write, the confirmation lists each value you are about to send, with ON or OFF for coils, and the full target: host, port, Unit ID and TCP or RTU over TCP. If you reconnect or change the target after Prepare write, the app cancels that write.
• If a device stops answering, the status shows Connection unconfirmed. Tap Reconnect and retry read to get fresh values without restarting the app. In Live monitoring, tap Reconnect, then Resume.
• Profiles, register settings and raw requests keep field labels on screen after you type a value, and VoiceOver reads them.
• Number keyboards have a Done button. Tap it to close the keyboard and reach the tabs; your input stays in the field.
• Logs list the newest entries first, each with your local time. A poll adds one row instead of two, so the log holds twice as many polls.
• Recent status separates the current result from previous events. If you cancel a write, the status says so. Profile summaries name register types and access in plain words, for example Holding registers and Read-only.
• Without saved profiles, the Client tab opens with Host, Port, Unit ID and Connect at the top. The form stays in place while you type a host.… more - ✏️Modbus TCP FieldKit: description updated· DE

- 📦Modbus TCP FieldKit updated to version 1.1.8Neu in 1.1.8:
• Besserer Kontrast im hellen und dunklen Modus. Die türkise Akzentfarbe erscheint jetzt auf Tabs, Links und Tasten, und die Status Aktuell, Veraltet und Fehler im Live-Monitoring haben ein Symbol neben dem Wort.
• Während einer Verbindung ist das Verbindungsformular kürzer: In der Sitzung gesperrte Felder und inaktive Tasten sind ausgeblendet, das Ziel steht im Status. Zum Bearbeiten tippen Sie auf Trennen.
• Schnell lesen zeigt auf dem iPhone bis zu 4 Werte des letzten Lesevorgangs.
• Uhrzeiten im Live-Monitoring und in den Diagrammen folgen dem Format Ihrer Region, auch im 24-Stunden-Format. Werte erscheinen nicht mehr als „-0“.

- 📦Modbus TCP FieldKit: now updating weekly4 updates in 30 days, after a quiet two months
- 📦Modbus TCP FieldKit updated to version 1.1.4Reading a device for the first time is now much easier.
• Quick read now has the area, address and quantity fields right in the panel, so you no longer need Advanced raw request to read a register.
• Connection and read fields now have labels that stay visible after you type, so Unit ID is easy to find.
• The first connection after installing waits for your answer to the Local Network prompt instead of failing.
• Reads through a gateway shared with another Modbus master (home automation, SCADA) now skip responses meant for that master instead of failing.
• Clearer advice when a device does not answer: Unit ID, devices that accept only one client, RS-485 converters in transparent mode.
• Fixed a crash on iPad with the floating keyboard.
• Live monitoring buttons now say exactly what they add.… more - 📈Modbus TCP FieldKit entered the top 100Top Paid · Utilities · DE

- 📦Modbus TCP FieldKit updated to version 1.1.0Der Servermodus zeigt jetzt, was Ihr SCADA- oder HMI-System schreibt.
• Werte, die ein SCADA, HMI oder ein anderer Modbus-Client in Coils und Holding-Register schreibt (Funktionen 05/06/15/16), erscheinen jetzt in der Register-Map.
• Von Clients geschriebene Werte bleiben erhalten, wenn Sie den Server stoppen und neu starten.
• Ein eingehender Schreibzugriff überschreibt nicht mehr den Wert, den Sie gerade eingeben.
• Adressen, die während einer laufenden Client-Abfrage hinzugefügt werden, verschwinden nicht mehr aus der Liste.… more - 📦Modbus TCP FieldKit updated to version 1.0.9Diagnostics improvement: when a device rejects a request, problem reports now include the exact Modbus exception code (for example, an illegal address), making it clear why a read or write failed.

About Modbus TCP FieldKit
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 or RTU over TCP device — read coils and registers, monitor data blocks in real time
• Modbus RTU over TCP — reach RS-485 devices through Wi-Fi or Ethernet converters in transparent mode (for example Elfin EW11, USR or Waveshare). If a read times out, the app offers to try the other framing with a single read.
• Find devices and Scan Unit IDs on your own Wi-Fi subnet — ports 502, 1502, 8899 and 4196. Each device is read once and nothing is written.
• Chart every monitored value — the app keeps the last 600 points or 1 hour per value while it is open — and Export CSV through the system share sheet.
• 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 diagnostic exports are sanitized by default
Requires Local Network access for device communication. RS-485 devices connect through a Wi-Fi or Ethernet converter in transparent mode. Default server port is 1502. Background server operation and port 502 support pending device validation.
