PLC Event Recorder — Powerful Data Logging for PLC Troubleshooting & Diagnostics

Log PLC digital events in real time and reduce troubleshooting time dramatically.

The Problem

"What Exactly Happened?" — Never Wonder Again

Your plant is controlled by one or more PLCs. Something out of the ordinary happens. Production time is lost, or product is damaged or destroyed. What exactly happened? You spend a lot of time investigating — and may even end up resigning to "let's see if it happens again."

The Event Recorder System developed by Brigger & Associates is software that monitors the changes in values of PLC digital conditions in a PLC program — which we call Events. Events are logged to a Windows PC database from which they can be displayed.

Digital conditions can be:

  • Digital Inputs
  • Digital Outputs
  • Alarms
  • Operator-issued commands
  • Any internal digital condition

Every Scan. No Exceptions.

A unique feature of the Event Recorder is that it monitors the values of digital conditions on every PLC scan. So no changes are missed — not even transitional ones.

Multiple PLCs at Once

In addition, multiple PLCs can be monitored at the same time — giving you one complete picture of your control system's activity.

How It Works

The Event Recorder Consists of Three Applications

1 — Event Collector

PLC Logic

PLC logic added to the host PLC that captures Events and temporarily stores them.

2 — Event Logger

Windows PC Program

Reads the stored Events in the PLC and saves them to a database.

3 — Event Viewer

Windows PC Program

Displays the Events in the user-friendly spreadsheet format described above.

The Event Recorder is ideal for:

Troubleshooting a PLC-controlled system Debugging a PLC program Optimizing PLC control performance
