8-19 Utility & Example Ladder Programs
Purpose
This program provides a way to upload, preserve, and download PLS configuration data (all PLS data other than pulse
data). Performing a read means uploading configuration data from the PLS and storing it in an N file. To preserve the

downloading the configuration data from an N file into the PLS.
