From FoxDoc B0193:
OSP or OSP sec or OSP Mxx
OSP generates a non-retriggerable (triggering is disabled while
output is true) one-shot pulse when the accumulator value makes a
zero-to-one transition.
I have a similar CALC block for clearing ACCUM blocks, but instead of
having BI01 set to 1 in ICC, I tie BI01 to BO02 of the CALC clock, and set
BO02 true only at the appropriate time.
If it is not the desired time, I set BO02 false. This makes a pulse at
BI01 (the length determined by the block PERIOD) so the accumulator has a
zero-to-one transition for the OSP operation to work with.
Then I "IN BI01 / OSP 5 / OUT BO01" as you do.

BI01 1
STEP01 IN RI02
STEP02 SUB RI04
STEP03 OUT RO02
STEP04 BIZ 8
STEP05 GTO 20
STEP06 =09
STEP07
STEP08 IN RI01
STEP09 IN RI03
STEP10 OUT RO01
