Hello Avatar; In Step 7 v5.5, reading and writing the Real-Time Clock can be done with the SFC 1 (Read_Clk) and SFC 0 (Set_Clk) standard functions, using Date_and_Time (DT) variables. Equivalent functions available in TIA Portal are shown in the screenshot below. How can you read out the date and time with SFC1 (READ_CLK) and set them with SFC0 (SET_CLK)? https://support.industry.siemens.com/cs/us/en/view/21222026 Note in the text above how the DT (Date_and_Time) variable is formatted and used with SFC 1. SFC 1 and SFC 0 can be used in LAD programming, STL is not necessary. You can add, sustract, convert and extract DT variables with other standard functions that are described here: Which functions are available in STEP 7 V5.x and in TIA Portal for processing the data types DT and DTL? https://support.industry.siemens.com/cs/us/en/view/63900229 Hope this helps, Daniel Chartier |
