17.1.137.2 Function at input value with sign reversal
Selection: C01150 = "2: Loading with level + reset"
[17-64] Switching performance if the input signal changes signs
• If "2: Loading with level + reset" is selected in C01150, 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 C01151/x
, the
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 C01151/x
, the
comparison value will be added to the counter content, and bStatus will be set to TRUE for
one task cycle.
