3.42 Memory Files and Data Structures

While the information related to Bagger settings may be stored internally on the PLC or externally on a USB Memory Stick
(Flash Drive) is similar in content, the data structures and methodology are different.
PLC Storage
Information regarding the settings for a particular job, such as Fill Time, Seal Temperature, and Bag Length, are
stored in the PLC as data files of various types. These data types include:
•
Integers – data type used to store whole numbers
•
Floating Point – data type used to store decimal numbers
•
Strings – an array used to store characters
These data files are stored in PLC memory and are accessible to the Ladder Logic of the PLC Program File.
