Modbus TCP FieldKit
Client, Server, Simulator
$4.99 · Designed for iPad. Not verified for macOS.
Client, Server & Simulator in one app. Bring up a Modbus TCP device from your iPhone and debug without hardware. Safe, confirmed writes.
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.
