The
compare value
is to be pre-defined by the
output area
. The
comparison
bit
may be found at the
counter status
at STS_COMP.
Please consider that the bit STS_COMP may only be influenced when in
the
counter status
the bit STS_CTRL_COMP is set.
The following behavior for the
comparison bit
may be pre-defined via the
parameterization:
•
no comparison:
Comparison bit
is not influenced
•
Counter value
≥
comparison value
:
comparison bit
is set
•
Counter value
≤
comparison value
:
comparison bit
is set
•
Counter value
=
comparison value
:
comparison bit
is set
no comparison
The
comparison bit
is not influenced.
Comparison bit is set when counter value
≥
comparison value
The
comparison bit
remains set as long as the
counter value
is higher or
equal
comparison value
.
Comparison bit is set when counter value
≤
comparison value
The
comparison bit
remains set as long as the
counter value
is lower or
equal
comparison value
.
Comparison bit is set when counter value = comparison value
When the counter reaches the
comparison value
the
comparison bit
is set.
The
comparison bit
remains set as long as the comparison condition is met.
When you've set a main counting direction the
comparison bit
is only set at
reaching the
comparison value
from the main counting direction.
Note!
The bit STS_COMP is set together with the bit STS_CMP in the
counter
status
. In contrast to the bit STS_COMP this bit remains set as long as it is
reset by setting the bit RES_SET in the
control word
.
