launches the tutorial.
What is CODESYS?
CODESYS is a program written by the German company
3S-Smart Software Solutions to program various PLCs. It is
written to conform to
IEC
61131-3, an open international standard for PLC programming
languages. Another program similar to CODESYS
called
TwinCAT
3 was developed by the German company
Beckhoff.
CODESYS has a built-in simulation PLC, built-in HMI capability
(Human Machine Interface or Visualization), and can be programmed in
various PLC languages, including:
- Ladder Diagrams (LD)
- Function Block Diagrams (FBD)
- Structured Text (ST)
- Instruction Lists (IL)
- Sequential Function Charts (SFC)
- Continuous Function Charts (CFC)
Who uses CODESYS?
CODESYS is used by companies such as Bosch, ABB, Moeller, Wago,
Eaton, Festo and others to program their PLCs.
What PLC Structured Text with
CODESYS V3.5 does:
This tutorial will show you step-by-step:
- how to use CODESYS to program PLCs using
Structured Text
- how to use CODESYS to run a PLC program in the
Simulated PLC
- how to use CODESYS to build an HMI (Human Machine
Interface) or Visualization
- the difference between various Data Types
- how to force inputs and outputs on and off
- how to program and use IF instructions
- how to program and use WHILE/REPEAT instructions
- how to program and use FOR instructions
- how to program and use CASE instructions
- how to program and use Timers
- how to program and use Counters
- what Boolean operators are and how to use them
- what binary, hexadecimal, and octal numbers are
- how to program and use Math instructions
- how to program and use Compare instructions
- how to program and use Select instructions
What PLC Structured Text with CODESYS V3.5 does NOT do:
This tutorial does not address:
- Instruction Lists (IL)
- Sequential Function Charts (SFC)
- Continuous Function Charts (CFC)
- How to connect CODESYS to a particular PLC
This tutorial was written using CODESYS V3.5 SP8, so if your version
of CODESYS is different your screens may look a little different
than the illustrations in this tutorial.
No prior knowledge of PLCs is necessary.
This tutorial is written by a Professional Engineer with 14
years industrial experience and 20 years experience teaching
electrical engineering technology at the college level.
If you want to learn how to use CODESYS to program PLC Ladder
Diagram and Function Block programs, you can purchase my PLC
Programming with CODESYS V3.5 tutorial at
http://www.knoware-online.com/codesys.html.
If you want to run and solve Ladder Logic programs without using
CODESYS you can purchase my PLC Simulator 8 at
http://www.knoware-online.com/pc-plc.html.
This simulator turns your PC into a PLC, has the "look and feel" of
Allen-Bradley RSLogix
® Micro software (though not exact),
runs and solves Ladder Logic programs that you write, and allows you
to build machines with limit switches, pilot lights, selector
switches, solenoids, and conveyors that move in response to the
ladder programs you write.
How to use this tutorial:
Chapters 1 though 5 of this tutorial explain how to download
CODESYS, install it, program instructions, build an HMI, and run
the program. Perform the tasks in these chapters verbatim until
you feel comfortable navigating within CODESYS. This
tutorial can be used without downloading CODESYS, but you will
lose the benefit of hands-on programming experience.
Chapters 6 thru 16 move at a little faster pace, explain many of
the more advanced instructions of CODESYS, and present example
programs that you can analyze and modify if desired.
