Programming LOGO!

Getting started with LOGO!
Programming refers to creating a circuit program from the LOGO! Base Module.
In this chapter you will learn how to use LOGO! to create the LOGO! circuit programs for
your application.
LOGO!Soft Comfort is the LOGO! programming software that you can use on your PC to
quickly and easily create, test, modify, save and print the circuit programs. The topics in this
manual, however, relate only to the creation of circuit programs on the actual LOGO! Base
Module. The programming software LOGO!Soft Comfort contains extensive online help.
Note
LOGO! versions without a display unit, that is, the LOGO! 24CEo, LOGO! 12/24RCEo,
LOGO! 24RCEo
and LOGO! 230RCEo versions, do not have an operator panel and display
unit. These devices are ideal for use in small machine and process equipment engineering
systems for series production.
You do not program LOGO!...o versions directly on the device. Inst
ead, you download a
program to the device from LOGO!Soft Comfort or from memory cards with the program you
created on another LOGO! device.
LOGO! versions without a display cannot write data to memory cards.
See Chapters "
Using memory cards (Page 269)", "LOGO! software (Page 283)" and the
A
ppendix "LOGO! without display ("LOGO! Pure") (Page 321)" for more information.
A small example in the first part of this chapter introduces the operating principles of LOGO!:
● You will learn the meaning of two basic terms, namely the
connector
and the
block
.
● As the next step, you will create a circuit program based on a simple conventional circuit.
● Lastly, you will enter this program directly in LOGO!
It will take you only a few pages of this manual to store your first executable circuit program
in the LOGO! device. With suitable hardware (switches etc.), you will then be able to carry
out initial tests.
