Hi, I'm on customer site and an unexpected CPU crash occured. Here enclosed the diagnose .txt file generated by the CPU. The CPU is referenced as 6ES7 416-2XK02-0AB0 and equiped with 2Mo RAM card. Can anybody give me a reason for this crash ?? Thanks in advance, Phil PS: The CPU restarted after power switch off/on and program reload. AttachmentDiagnose_100606.zip (159 Downloads) |

Hello Philip; Your diagnostic buffer contents all seem to refer to an anomaly in your hardware configuration, that required a new download to correct: -Le microprogramme interne de la CPU a constaté un état incohérent. <the CPU internal microprogram had encountered an incoherent state> -La CPU a été remise à l'état initial par une surveillance de temps interne (chien de garde). <The CPU has been reinitialized by the internal watchdog> -Une erreur s'est produite lors de l'évaluation de données de configuration, par exemple lors de l'envoi de paramètres à des modules de signaux. C'est pourquoi la mise en route a été inhibée ou l'état de fonctionnement ARRET demandé. <An error was encountered while evaluating configuration data, for exampole while downloading parameters to signal modules. This is why the startup has been inhibited or Stop mode has been requested> Why this corruption of SDBs happened is not registered in your present diagnostic buffer extract. What diagnostic OBs are installed in the CPU (OB82/83/85/86/121/122)? These would help the diagnostic buffer locate the source of the problem, if possible. Have a look at the French version of Programming Step 7 (Programmer avec Step 7, v. 5.4): http://support.automation.siemens.com/WW/view/fr/18652056 The chapter on Diagnostics will provide much information, especially when discussing the IStack (in French: les Piles de diagnostic) if the problem happened while processing a particular block. Hope this helps, Daniel Chartier |
