You can prevent the CPU from going to stop by programming the appropriate OB but you should consider the implications for a running plant before doing so. See attachment and also checkout the following manuals: SIMATIC S5-135U/155U System Manual http://support.automation.siemens.com/WW/view/en/1085837 S5-135U/155U List of Operations http://support.automation.siemens.com/WW/view/en/1086150 Attachment Pages from 6ES5 998-OSH21.pdf (60 Downloads)
