Siemens S7-300/400 (Modules 1-4) Training Course

This module provides an overview of the Siemens S7-300 system. The training demo is introduced, as well as hardware and system components used in a typical SIMATIC Step 7 system. Step 7 software is reviewed and students will set the PG interface. Configuring hardware is next and then students will receive insights into determining a module’s status. Memory concepts are covered along with how to create symbols and monitor/modify them with a variable access table. To complete the module the student will be able to use and interpret the bit logic instruction in ladder logic and statement list.

This module begins with a review of the numbering systems used in PLC’s and then students will learn about accumulator memory; the basic instructions used to move values. Timer and counter instructions for the S7-300 and S7-400 families are covered. Next, data blocks are covered including how to address, edit, create and view in a VAT table. To conclude the student will learn to configure the clock memory byte in Step 7.

This module will give the student the tools that they need to be able to use OB Blocks including an overview, priority, startup, cyclic, asynchronous and synchronous blocks. Next, math and compare operations using STL programming are covered. The student will learn how to use Function Calls, Function Blocks and how to monitor a specific instance of a FC or FB block called multiple times in a program. To complete the module the student will understand the various types of jump operations that are possible in STL and the operation of the Label instruction.

This module will review Analog I/O and introduce I/O used on PROFIBUS. The student will then go on to Searching, Reference Data, Block Compare and Forcing. To complete the module a review of troubleshooting skills and Common Step 7 Tasks.
