Hello, The OB100 is a restart OB and is run when the CPU is restarted (warm start). You can write there code which enable soem act immendiately aftwer restrt of CPU. For example to enable communication blocks like http://support.automation.siemens.com/WW/view/en/18516182 . About OB10 look at Setting the time-of-day interrupt Best regards, Hristo Mihalev |
