Target Audience
This course is for SIMATIC S7-300/400 PLC users with engineering experience in the design and configuration of automation systems and their application programs The student must be able to understand advanced programming topics.
 
Prerequisites
S7 Programming I 
 
Class Description
This course reviews S7 programming concepts and structures. Advanced programming with complex structures, multiple addressing methods, and special program control instructions is covered. The knowledge this course provides makes it easier for students to solve complex programming problems. Software tools help students analyze advanced alarm issues, such as process or error interrupt alarms. The course format consists of instruction and hands-on exercises.
 
Class Objectives
Upon completion of this course, the student should be able to:

  • Employ status bit-dependent commands, accumulator operations and extended floating-point arithmetic.

  • Use complex structures with parameters.

  • Employ indirect addressing in a program.

  • Incorporate system functions (SFC) in a program.  

  • Understand the use of SIMATIC S7 libraries.

  • Use complex data structures for data management.

  • Use interrupt-driven and error processing program execution blocks.
