Blocks and block numbers
This chapter shows you how to use LOGO! elements to create complex circuits and how
blocks and I/O are interconnected.
In the topic "From circuit diagram to LOGO! program (Page 59)" you will learn how to
In the topic "From circuit diagram to LOGO! program (Page 59)" you will learn how to
transform a conventional circuit into a LOGO! circuit program.
Blocks
A block in LOGO! represents a function that is used to convert input information into output
information. Previously you had to wire the individual elements in a control cabinet or
terminal box. When you create the circuit program, you interconnect the blocks.
Logic operations
The most elementary blocks are the logic operations:
● AND
● OR
● ...
● AND
● OR
● ...
These special functions offer you significantly greater performance:
● Pulse relay
● Up/down counter
● On-delay
● Softkey
● ....
