Data Logging

 

Introduction

This document explains the data logging functionality for controllers that support file management operations.

A data log is a text file of user-defined strings that contain application data information for a process or machine. The data log file is stored on the controller. You can upload the file and open it with a standard text editor. The information includes embedded variable values and their associated text. Time and date stamping are additional options.
