Block representation on the LOGO! onboard display 

The figure below shows a typical view of the LOGO! onboard display. As you can see, it can 

show only one block at a time. We have therefore introduced block numbers to help you 

check the circuit structure.

Assigning a block number 

LOGO! assigns each new block in a circuit program a block number. 
LOGO! uses these block numbers to indicate the block interconnections. This means that 

these numbers are mainly an aid to your orientation in the circuit program.

The figure above shows you three views of the LOGO! onboard display, which represent the 

circuit program. As you can see, LOGO! interconnects the blocks using their numbers. To 

scroll the circuit program, use the key  . 

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.
