S7-300 timer for at least 24 hours

Hello guerrez;

I have no troouble following Pegaia's FAQ link.

Maybe the Moderators should look into this issue, as it is not the first time that downloads and FAQs appear in different languages or are simply not available though the new Siemens Forum... Local time zone settings maybe?

In the meantime I have taken the liberty of making a pdf og the requested FAQ (see attachment0 and i add here the link to the code provided by Pegaia:

Hope this helps,

You can use SFB TON/TOF/TP where timer setpoint is provided as a 32-bit integer (TIME data type) which internally shows time in ms.

This timer has max range of a bit more than 21 days and is easy to display on hmi/scada - display it as an integer with 3 decimal places i.e. 12345 display as 12.345seconds

if you want less precision you can have a separate integer setpoint tag which is multiplied by
a conversion factor (x1000 for seconds, x100 for xxx.y seconds, etc.)
