Training - S7 Programming I

Target Audience
This course is for SIMATIC S7-300/400 PLC users who are involved with developing or maintaining automation systems and their application programs.

Prerequisites
MS Windows Expertise

Class Description
This course introduces the S7 product family and provides an overview of the SIMATIC S7-300/400 system. Hardware and software components as well as system configuration issues are discussed.
The course uses a realistic conveyor model for demonstrations and exercises. This course concentrates on STEP 7 software, program structuring and the instruction set. STEP 7 software tools and programming instructions are demonstrated to guide the student through the development of a realistic application. Analog processing and alarming are detailed through theory and program examples.

The course format consists of instruction and hands-on exercises. Students will use test, debug and diagnostic tools to complete the programming exercises.


Class Objectives
Upon completion of this course, the student shall be able to:

• Identify the components and performance characteristics of the SIMATIC S7-300 PLC.

• Program using the multiple address types.

• Use symbolic addressing.

• Create, document, test and troubleshoot an application program.

• Use binary operations, timers, counters, comparators, and arithmetic operations.

• Structure a program that can use a program block multiple times.

• Use the data access functions.

• Program using the processed analog values.

• Generate data blocks.
