Course Description
This 40-hour course introduces the Siemens SIMATIC S7-300 controller. It explains the different components of the system. It includes basic ladder logic instructions and how they are used and programmed. It shows how to configure the PG/PC Interface. It also teaches how to use the programming software to obtain information from the process and also from the PLC itself. It gives general guidelines on troubleshooting and maintaining a PLC system. The course emphasizes hands-on laboratory exercises using Siemens SIMATIC S7-300 controller and either the Step 7 or TIA Portal Software. Each student will be expected to purchase the following textbook if they want a copy to keep following the course: Automating with Step 7 in LAD and FBD by Hans Berger - ISBN 978-3-89578-410-1.
