PLC-API bWaitTimeActive : A TRUE at this output indicates that the waiting time between the switching actions of the output signals is active. This output can be used to hold an I component that may be present in the prior controller constant during this time. TYPE ST_CTRL_MULTIPLE_PWM_OUT_DATA : STRUCT Interne Struktur.
