Example:
Program
with 3 traversing
blocks
1 The block is executed, if at least one of the bits, configured in the
start mask, is not set. No
0 Normal evaluation
1 The following is valid dependent on the condition defined in
SMStart:
SMStart type
(from SW 1.2)
fulfilled
not fulfilled
then the block is executed
then the block is skipped No
0 Wait until the start condition is fulfilled according to SMStart. The
block is executed if the condition is fulfilled and ”Execute block”
is present.
