PULSE OUTPUT FUNCTION FOR PROGRAMMABLE LOGIC CONTROLLER WITHLINEAR FREQUENCY CHANGE

摘要

Certain exemplary embodiments provide a method for producing pulsed outputs, comprising: automatically changing a first user-specified pulse frequency to a second pulse frequency; and automatically outputting a plurality of pulses from the programmable logic controller at frequencies varying between the first user-specified pulse frequency and the second pulse frequency accordin g to a user-specified linear-time-rate variation
