      @robert_n You have to create your own function block in ST (have to be switched to full mode), past the code from the example above and create an Integer new variable, which will represent the time in seconds (you can easily change it in the function block to minutes).

      Then in the Main program, just pass the integer variable through the new function block to the TIME variable and you are done.

        @tomas_hora Unfortunately that did not work for me because I do not use TIME variables, but TIME_OF_DAY. When I try to connect these two types, the compiler throws an error. I found a workaround to convert to TIME_OF_DAY with add_tod_time. This method means a lot of work to program the Function and HMI and it becomes slightly confusing...

          @robert_n Well for that purpose, you could use one of the provided schedulers or no?

            I have tried to do the function block
            But i just get "build fail."
            Do I have to write any more parameter in the block or matter it works directly

            FUNCTION_BLOCK IntlToSec
            	VAR_INPUT
            		seconds_int: int;
            	END_VAR
            	VAR_OUTPUT
            		out_time : TIME;
            	END_VAR
            
            out_time := mul_time(time#1s, seconds_int);
            END_FUNCTION_BLOCK

                Indicates that it is wrong in any column
                But the error changes depending on where I have the cursor standing

                  @zorro_66 Could you share the project? That might be easier to debug...

                          @zorro_66 All input variables of a function block has to be connected or checked as not visible and set a default value. That is missing in your BD13_SwitchOffDelay of Interlocks program.

                          The second issue is, that in the PLC program mapping, you have mapped two programs that do not exist...

                            Thanks for the quick reply Tomas
                            Well, I know I had nothing connected to that block but did not think it was the fault.
                            Because it's on the position my time_Converter was supposed to enter.
                            Which two programs have I mapped that are not available

                              @zorro_66 if you double click on the error in the result table, it will usually show you where the issue is... Or just read what it says.
