Siemens Step7 Software - 2-day Introduction to Programming
Applied Controls, Inc. has put together an introductory course to the Siemens "Step7" Software. The Step7 Software Version 5.4 is a comprehensive set of software tools for developing and debugging programs for the Siemens S7-300, S7-400 and C7 programmable controllers.
In this two-day course, we explore the navigation methods used in Step7 to give the user an overall view of the projects he will develop. Features of hardware setup, I/O configuration, and Profibus networks are explored first. We look at the common "tools" in programming relay ladder logic - timers, counters and simple logic.
We then look at structured programming methods that are the mainstay feature of Siemens' Programmable Controllers. A dissertation on Organization Blocks, Function Calls and Function Blocks explains the common methods used in structuring your program.
We highlight Organization Blocks to understand their purpose in startup, error trapping, and interrupt handling. We demonstrate how Function Calls can be used as subroutines, Data Blocks get used for operator interface and mathematical formulas and Function Blocks become instrumental in recipes.
We conclude the session by taking completed programs and focus on debugging methods by using charts, on-line help menus, cross-references of elements in the programs, and how to document and print the programs.
The course uses an overhead projector with direct link to computer, blackboard emphasis and hands-on work with new P4 Training Computers, with LCD Monitors, to present the course material. We try to keep the workshop attendance under eight people so that each person can gain experience.
