Hello, As far as i know All CPU 224 have a RTC. You can check it by selecting your CPU(and FW version) in Microwin, if there is no red cross through the Read_RTC function it does have a clock. To create the desired function: How can you read out the S7-200 CPU clock and output the values in integer format and how can you set the S7-200 clock with default integer values? You can then easy use a compare-int function to do your actions. regards, Marcjan |

Hello, thank you for the answer. I will order the battery module to keep the RTC working during holidays and weekends. |
