6. Function blocks6.1 Manufacturer function blocks6.1.1.4 RC - Real-time clockGeneraleasyE4 base devices provide exactly one real-time clockRC01.This function block can be used to read the date and time valueof the device's real-time clock. This value is output in sevenindividual parameters than can each be processed further indi-vidually. This makes it very easy to select recurring eventswith a downstream comparator function block.Operating principleIf the function block is enabled, the date and time value from the device's real-timeclock will be output at the function block outputs: YY (year), MM (month), DD (day), WD(day of the week), HR (hours), MN (minutes), SC (seconds).Function block output DT signals whether the clock has been switched to daylight sav-ing time.The function block and its parametersFunction block inputsDescription Note(Bit)EN 1: Activates the function block.
