Siemens S7-300/400
(Modules 1-4)
Duration: 4 days
Audience: Anyone needing to maintain or program an S7-300/400 project using Step 7 Classic
Prerequisites: Basic Computer Skills

Course Outline

Module 1

This module provides an introduction and overview of the Siemens S7-300/400 product. The training station used during the class is reviewed along with the Siemens PLCSIM software and the students will set the PG interface. Students will create an S7-300 project and hardware configuration, cover module status and memory layout. The module completes with the creation of symbols and a key troubleshooting tool – the VAT table.
