Hello, I think this FAQ will describe your question best http://support.automation.siemens.com/WW/view/en/38051505 And according to that you don't need to do an upgrade, but in general its best idea to upgrade for dozen other reasons. If you want to upgrade firmware of your PLC just check this link http://support.automation.siemens.com/WW/view/en/41886031/133100and find your PLC model in the list to upgrade. |
