These channels all actjointly on the function block output Q1 of the weekly timer.Operating principleEach of the 32 weekly timer, HW01 through HW32, features four channels that caneach be configured with an ON event and an OFF event in the parameter configurationfor the block. All channels act jointly on function block output Q1.The following abbreviations are used for the individual days of the week:Monday = Mon, Tuesday = Tue, Wednesday = Wed, Thursday = Thur, Fri = Fri, Saturday= Sat, Sunday = Sun.The function block and its parametersFunction block inputsDescription Note(Bit)EN 1: Activates the function block.
