Run Duration Control (FbRunDurationControl)Function Description:This function block controls activation and deactivation of the three outputs“xOutput(1-3)“ depending on their hours of operation.If a “TRUE“ signal on one of the three inputs “xStart(1-3)“ gives the command toactivate one output, then the output having the shortest operating period will be setto “TRUE“.If another input xStart(1-3) is set to “TRUE“, the output with the next longer operatingperiod will be activated.Deactivation of the outputs will also be made depending on operating periods. Areset of a start signal will result in deactivation of the output with the longestoperating period.The function block is provided with the operating periods of the outputs via the inputs“rHour(1-3)“. The operating period can be determined using for example thefunction block FbOperatingTime.A typical application for this function block is the use in strip lighting (switching on /off 1/3, 2/3, or 3/3).Example of application:Subject to design changes WAGO Kontakttechnik GmbH & Co.
