Date and time not working. (Help)

[Avatar_41]

Hello guys, I want to use the project in the link. (https://support.industry.siemens.com/cs/document/*1***0*6/how-can-you-read-out-the-date-and-time-with-sfc1-(read_clk)-and-set-them -with-sfc0-(set_clk)-?dti=0&lc=en-WW).
The time and date reading part of the project works, so I can see the values, but when I want to change the time, it does not respond. I am sharing my project below, can you help me please? Good work.

You need to understand how to use function blocks and their instance data. When you call an FB, the value of the input is copied to the instance DB - so it does not make sense to use the instance data itself as the passed parameter - similarly for the output data.


The reason your date setting does not work is because the edge detection storage bit is declared as an input - it needs to be a STAT.

My English is not very good, so I don't know how to apply what you said. Can you compile the project as it should?
