Programming Logo - Siemens LOGO! Series Manual

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! 24o, LOGO! 24Co, LOGO!
12/24RCo, LOGO! 24RCo and LOGO! 230RCo versions, do not have an operator panel and
display unit. They are primarily designed for use in small machine and process equipment
engineering systems for series production.
LOGO!...o versions are not programmed directly on the device. Instead, the circuit program
is downloaded to the device from LOGO!Soft Comfort or from memory cards or combined
memory/battery cards from other LOGO! devices.
LOGO! versions without a display cannot write data to memory cards or combined
memory/battery cards.
See the chapters "Applicable cards (Page 303)", "LOGO! software (Page 313)" and the
appendix "LOGO! without display ("LOGO! Pure") (Page 351)" 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! unit. With suitable hardware (switches etc.), you will then be able to carry out
initial tests.
