PLC Analog Recorder — Real-Time & Historical Data Logging for Process Monitoring

Monitor temperatures, pressures & process values across multiple PLCs — live and historical trends.

Analog Recorder plotting PLC analog values as a function of time — Real-time trend plot with value sliders

What It Does

Watch Your Process Values — Live and in History

The Analog Recorder is software that allows you to monitor the values of your PLC analog points — temperatures, pressures, levels, etc.

It does this through a graphic that plots the values as a function of time. Up to 6 points can be plotted at a time, each in a separate color and a separate scale. Individual values along a plot line are displayed using horizontal and vertical sliders.

The Analog Recorder reads the values of specified PLC analog addresses and saves them to a database. The values can be displayed as they are read, providing a real-time trend of the data — and saved data can be displayed for a specified time and date.

Features

Built for Continuous Process Visibility

Multiple PLCs

The analog points to be logged can come from multiple PLCs.

Logs Every 60 Seconds

Analog points are logged every 60 seconds, continuously, while the system runs.

Operator-Set Retention

Logged values are stored for an operator-specified number of days.

Unlimited Points

There is no limit on the number of points that can be read and logged.

Up to 6 Plotted at Once

Plot up to 6 points at a time, each in a separate color and separate scale, with value sliders.

Export to Text

Logged values can be exported to a text file for analysis or reporting.

How It Works

The Analog Recorder Consists of Two Applications

1 — Analog Logger

Windows PC Program

Reads the analog values in the PLC and saves them to a database.

2 — Analog Viewer

Windows PC Program

Plots the saved data. The reason these are separate applications is so the Analog Viewer can be installed on multiple workstations.
