US - Anton - 04 / PLC - 1 (CPU 1214C DC/DC/DC) / Program Blocks: Main (OB1)

This document summarizes a PLC program that controls an automated process. The program uses networks of logic to: 1) Start and stop the process based on input signals; 2) Activate and deactivate pumps, heaters and other equipment in sequence; 3) Use timers to control the duration that equipment runs.
