Programming LOGO!
3.9 Memory space and circuit program size
LOGO!
110
Manual, 06/2014, A5E33039675
The second limitation is based on the maximum number of bytes a circuit program can
contain. You can determine the total number of bytes used by adding up the number of
bytes used for the relevant function blocks.
● Retentive memory (Rem):
In this area, LOGO! stores values that are retentive; for example, the hours counter
value. Blocks with optional retentivity use this memory area only if you have enabled the
retentivity function.
Resources available in LOGO!
A circuit program in LOGO! can occupy the following maximum resources:
LOGO! device series
Bytes
Blocks
REM
LOGO! 0BA8
8500
400
250
LOGO! monitors memory utilization, and offers only those functions from the lists for which it
can actually provide sufficient memory space.
