Siemens S7-300/S7-400 with STEP 7 Course Modules

السلام عليكم

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

Duration: 4 days

Course Outline

Module 1

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.

Module 2

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.

Module 3

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.

Duration: 4 days

Course Outline
Module 5

The first part of this module reviews the concepts of Function Calls, Data Blocks and Funtion Blocks and includes some more advanced exercises for refreshing on key concepts. The module concludes with a significant amount of material covering indirect addressing methods such as POINTER and ANY data types, memory indirect and register indirect addressing methods.

Lessons

Data Blocks
Function Blocks
Indirect Addressing

Module 6

This module introduces the student to the system functions that copy sections of memory. Next, memory concepts in an S7 processor are covered. The student will learn instructions that shift or rotate bits in memory words and double words. All the shift and rotate instructions are covered for LAD, FBD and STL. The student will describe the operation of a Multi Instance Data Block, as well as, troubleshoot programs and create a Function Block. To finish the module Word Logic Instructions are covered.

Lessons

Copy Functions
Memory Concepts
Shift and Rotate Instructions
Multiple Instances
Word Logic Instructions

Module 7

This module begins with Clock Functions where the student is shown how to handle date and time in an S7 program. Next, the student will be introduced to the concepts of the Structured Control Language covering source files, the SCL Editor, compiling and monitoring. The student will understand the different structures for each block and the order and attributes of the blocks will be discussed. The module concluded by covering the essentials of programming expressions and statements in SCL.

Lessons

Clock Functions
Introduction to SCL
SCL Program Structure
SCL Program Statements

Module 8

This module starts by going over the debugging tools in the STEP 7 software. Next is an overview of PID control and how it is implemented in the Siemens PLC. The student will be introduced to the concepts of Sequential Functions Charts (a.k.a. Grafcets) and finally, the S7 GRAPH programming language used for sequential controls is thoroughly covered using examples and exercises.

Lessons
