● Outputs AS-Interface (Qa (Page 25))
LOGO! restricts the nesting depth for your circuit program. Your circuit program has a
maximum nesting depth of 58 objects.
This determines the following:
1 input + 56 blocks +1 output
This determines the following:
1 input + 56 blocks +1 output
Max. depth of a circuit program = 58 objects

During a simulation or download, the system returns an error message if you enter a
program in LOGO!Soft Comfort that exceeds the maximum nesting depth.

Implementing large circuit programs
You can implement large circuit programs by means of signal recursion. You implement
signal recursion by appending a flag block (Page 195) to the end of the program and
connecting the remaining blocks to the output of the flag block. LOGO! interprets the flag as
the output of the first program and also as the terminal block of the downstream blocks.
LOGO! interprets the large program with flag as two separate programs. If no more flags are
available, you can use an output block instead.
