Ideal for you if…

  • You are ready to expand your knowledge of Siemens S7 programming beyond basic ladder logic

  • You need to program logic which includes repetitive tasks (subroutines)

  • You want to learn how to use Data Blocks (DB) in conjunction with Function Blocks (FB) to support complex logic structures

Description

FBs and FCs are used in Siemens S7 programming to define functions that can be executed on demand from an organization block. FBs and FCs are similar to subroutines and can simplify programming where the same task is needed multiple times within the program.

In this course, practical control examples will be used to demonstrate the use of these functions and function blocks. An FC block will be configured to calculate the level in a tank with a trapezoidal bottom. Input and output parameters will be configured to allow the FC to be used as a subroutine to calculate the level in three parallel tanks.

To demonstrate the use of a Function Block, two different examples will be developed. First, an FB will be used to monitor and control an on-off valve, including driving the valve output, monitoring the valve position feedback, and developing a command disagree alarm if the valve state does not match the commanded state after a time delay.

The second example will demonstrate a more complex use of an FB using a Data Block to support the execution of the FB logic. A DRUM sequencer will be configured in the FB to control a simple process as it progresses in a stepwise fashion.

From my experience, I have to say that RealPars is the most professional online training program out there. The instructors are easy to follow and clearly explain PLC theories with excellent supporting visuals and real-life application examples. I like that they provide a summary after each lesson that brings together all the information and makes it easier to retain. Plus, I can train anytime, anywhere. I’m a maintenance apprentice right now, but when I complete RealPars training I’ll be ready to go after the PLC programming jobs I want.

Mohammad Khabazi

I work on electrical and instrument maintenance now, but my goal is to become a full-time PLC programmer. University courses take too much money and time. The RealPars video training method is great…the instructors are all experts and speak clearly so they keep my interest and are easy to follow. I’m eager to gain even more PLC expertise as new content is added.
