From Circuit Diagram To Logo! Program - Siemens LOGO! Manual

Advantages of block numbers
You can connect almost any block to an input of the current block by means of its block
number. In this way, you can reuse the interim results of logical or other operations, reduce
programming effort, save memory space and clean up your circuit layout. To do so, however,
you need to know how LOGO! has named the blocks.
Note
An organizational program chart can be a valuable aid when you create the circuit program
because you can enter in this chart all the block numbers that LOGO! assigns.
By using the LOGO!Soft Comfort software to program LOGO!, you can directly create a
function chart of your circuit program. LOGO!Soft Comfort also allows you to assign eight-
character names to up to 100 blocks, and to view these on the LOGO! onboard display in
parameter assignment mode. See the topic "The four golden rules for operating LOGO!
(Page 66)".
