Blocks And Block Numbers - Easy Electronics xLogic Micro PLC User Manual

The illustration above with numbered AI inputs shows the conceptual usage of the inputs, not the actual
physical markings on the module.
xLogic's connectors
The term connector refers to all connections and states in xLogic .
The digital I/O status can be '0' or '1'. Status '0' means that the input does not carry a specific voltage.
Status '1' means that the input does carry a specific voltage.
The 'hi', 'lo' connectors have been introduced to make it easier for you to create the
circuit program:
'hi' (high) is assigned the status '1',
'lo' (low) is assigned the status '0'.
You do not have to use all of the connectors of a block. The circuit program automatically assigns the
unused connectors a status that ensures proper functioning of the relevant block. For information on the
meaning of the term "block", refer to the topic on "Blocks and block numbers ".

5.2 Blocks and block numbers

This chapter shows you how to use xLogic elements to create complex circuits and how blocks and I/O
are interconnected.
In the topic "From circuit diagram to xLogic Program" you will learn how to transform a conventional
circuit into a xLogic circuit program.
Blocks
A block in xLogic 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. To do so, simply select the connection
you require from the Co menu. The menu name Co is an abbreviation of the term "Connector".
Logic operations
The most elementary blocks are the logic operations:
● AND
● OR
● ...
