Every engineer working with Modbus devices has lost hours to this:
❌ Installing software on a laptop/PC
❌ Reconfiguring baud rate, parity, slave ID — every single time
❌ Copying logs into Notepad to share with the team
❌ "It worked on my machine" — because configs weren't shared
We built CAPUF Modbus Terminal to fix all of this.
🔌 Connect in 5 seconds
Open the browser. Plug in USB-RS485. Click Connect. No drivers. No Python. No COM port confusion.
📁 Save 100s of devices
VFDs, PLCs, energy meters, RTUs — saved with slave ID, baud rate, and register map. One click to reload. Share with the whole team via a single link.
📷 Screenshot · Save log · Stream to file
Capture exactly what you see → PNG. Every TX/RX timestamped → .csv. Live append to disk for overnight soak tests — no babysitting.
🎛 Control Visualization — no code
Command buttons, command status LEDs, read-only indicators, register bars. Your device dashboard, in the browser, shared in one link.
📈 Plot & analyze live
Any register → live chart. Zoom, select, get min/max/mean. Catch intermittent faults before they vanish. No post-processing Excel.
★ Free for the first 1,000 users
Full access. No credit card. No trial expiry.
