Advantages Of Block Numbers - Siemens Logo! Manual

Programming LOGO!
The figure above shows you three views of the LOGO! dis-
play, which represent the circuit program. As you can see,
LOGO! interconnects the blocks using their numbers.

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, re-
duce 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
We advise you to create an organizational program chart.
You will find this a valuable aid when you create the circuit
program because you can enter all the block numbers that
LOGO! assigns in this chart.
By using the LOGO!Soft Comfort software to program the
LOGO!, you can directly create a function chart of your
circuit program. LOGO!Soft Comfort also allows you to as-
sign eight-character names to up to 64 blocks, and to view
these on the LOGO! display in parameter assignment
mode (see Chapter 3.5).
