Ideal for you if…

  • You are a technician or engineer and need to gain a strong working knowledge of the SCL language for PLC applications

  • You have basic ladder logic programming experience but want to learn more advanced programming techniques by creating program blocks in SCL using a real-world process example

  • You want to practice taking complex process descriptions and create PLC logic to create a functioning program to meet those requirements

Description

Siemens CPU models typically allow three standard languages, Ladder Diagram, Function Block Diagram, and Structured Text, to be used to program blocks of code. In Siemens applications, Structured Text is called “Structured Control Language”. In addition, Instruction List and Sequential Function Chart programming are also available with some Siemens CPUs to ensure total alignment with the IEC 61311-3 standard.

SCL provides the engineer with a more computer language-like environment with which to develop logic within the PLC. TIA Portal provides an SCL editor that is used to construct the logic and frame the program statements. Toolbars, instruction libraries, and other tools are provided to make the creation of SCL code easier.

This course will present the basic rules, statements, and structures that need to be understood prior to developing the program code. A real-world example of the control of a 2-way on-off valve will be used to provide the specification for development of specific program logic that will be downloaded and tested in an S7-1200 simulation environment.

Troubleshooting tips for SCL programs, as well as online diagnostic information, will be given to provide the control engineer with a rich set of tools that will allow SCL to be added as a valuable addition to their programming knowledge.

Marcin Trojak

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.
