19.1.141.2 Function at input value with sign reversal
= "2: Loading with level + reset"
[19-64] Switching performance if the input signal changes signs
• If "2: Loading with level + reset" is selected in
, the bLoad input is status-controlled: In
case of a TRUE signal, the integrator is loaded with the value at dnSet_p and the bStatus output
is set to FALSE.
• A positive signal at nIn_v is incremented (the counter content is increased with every function
call).
• A negative signal at nIn_v is decremented (the counter content is reduced with every function
call).
• dnOut_p outputs the counter content of the bipolar integrator.
• If the positive counter content is higher than the comparison value set in
comparison value will be subtracted from the counter content, and bStatus will be set to
TRUE for one task cycle.
• If the negative counter content is lower than the comparison value set in
, the
comparison value will be added to the counter content, and bStatus will be set to TRUE for
one task cycle.
