I'm sending multiple values from delays ect. to LOGO and receive them wel, but when i for example send the value 4 for ON. I receive something as 238798. Anyone tips on how to resolve an issue like this? Thank you in advance!

You're doing it right in the LOGO! by the Parameter-VM_Mapping, you take a DWord (VD14). The format is DInt. In TIA you only use one word, VW14. This is wrong. You have to enter a double word in the variable table, VD14 with the format DInt. Because you only write in TIA in the word VW14, you write in the higher-order word of the double word. This will give you the wrong value of 238798.

And so I had to change it to VW24 in LOGO and TIA, otherwise it was changing when i changed VW16. Now suddenly i have the same problem, for my interval on-delay timer. when it's 60 minutes, it gives me in the HMI a value of 36:00. This is a word in LOGO and a int in TIA.

The value is the total in seconds, because the time base is in your case seconds. So 60 min = 60 * 60 s = 3600 s. And if you in TIA to this value it is time format, then makes TIA from 3600 then 36:00.

Eventualy there was decided to not integrate it in the HMI, but now with a new project it is a must... The excact same problem: if in logo the ON-delay is [min;sec], 36:00 on the HMI is 60 min and if i try it in [hours;min], 1:00 on the HMI is 1 hour and 40 minuts in LOGO. What's correct, but as you understand I prefer not entering it on the sreen in another time base, because it's calculated another way. I understand that it has to be the data type 'time' in the HMI, but I can't select it probably because of the HMI type KTP400 or just because LOGO doesn't have that option in combination with a S7 screen? Is there another way? Thank you so much in advance!

Nothing can be changed about that. Example: time base minutes, i.e. when entering the LOGO! with the format "h: m". An example is 1 hour and 40 minutes. The LOGO! then transfers the value 100 to the HMI (1 x 60 + 40 = 100).
