Please refer to the manual, page 1-12 http://support.automation.siemens.com/WW/view/en/1214574 If a cyclic interrupt OB has not been completely executed before it is due for execution again because the interval has expired, the time error OB (OB80) is started. This way you will know when time is exceeded |
