See what your PLC is doing —
in seconds.

Diagrix reads and plots Allen-Bradley PLC tags in real time, so you can spot a fault the moment it happens — no expensive license, no complex setup.

GRAPH 1 · LIVE

Up and running in < 2 min

Type an IP, pick your tags, and watch them live. No project files, no server, no training.

No expensive license

A lightweight tool priced for field use — not a five-figure proprietary suite.

Catch intermittent faults

Unlimited rolling recording to disk captures problems that only show up hours apart.

Works without a PLC

Built-in simulation lets you learn the tool, build a layout, or record a demo offline.

Everything you need to diagnose a machine

Purpose-built for automation and maintenance engineers who need answers fast.

Real-time multi-panel

Up to 6 independent graphs at once, each with several signals.

Digital & analog

On/off bars for BOOLs and live lines for numeric tags, including REAL floats.

Alarm thresholds

Set min/max per tag; Diagrix draws reference lines and logs each crossing.

Pause & dual crosshair

Freeze the plot and drag two cursors to read the exact time delta.

Browse PLC tags

Pull the tag list straight from the PLC and cache it locally — one query per IP.

Chain Map

Ping-scan a daisy-chain or LAN and see instantly where the network is cut.

Connector pinouts

Offline reference for RJ45, PROFINET, RS-485, PROFIBUS, encoders and more.

CSV recording & export

Snapshot the view or record continuously for post-mortem analysis.

Three steps to a live trace

If you can type an IP address, you can use Diagrix.

1

Set the PLC IP

Enter the controller's address and hit Test Connection to confirm it's reachable.

2

Pick your tags

Type them in, or Browse PLC Tags to select straight from the controller.

3

Watch it live

Hit Activate Tag and the signal streams in real time — pause, zoom, and record.
