Hello kelese I'm afraid to say that Step7 is lacking an inbuilt tracing or trending tool. While you can sort of (ab)use the PID control Parameter assigment tool for this purpose and/or come up with Excel based logging and pseudo trend (e.g via OPC, libnodedave etc.)it's all a bit archaic. I suggest you have a look at a tool that I use all time whichcalled ibaPDA-S7-Analyzer. It's one small part of what iba has on offer and THE tool for anyone who deals with S7 PLC's for a living as far as I'm concerned (be it commissioning, troubleshooting, PID tuning, general control system optimisation etc. etc.). As I alsowork for iba Oceania I will declare a conflict of interest with this advice (but like to think I would give you the same advice if this wasn't the case). I hope this helps |

S7 PDIAG which comes with Step7 Professional can help you on this regard. |

Sorry manmeet, PDIAG is an optional add-on to Step 7 that is NOT included in the scope of delivery for Step 7 Professional. Let's say you buy PDiag though, you get a (rather sophisticated)Engineering tool that allows you to configure Process Diagnostic related messages (e.g. adress monitoring, motion monitoring etc.), butas far as I'm aware, it does not have a trace tool inbuilt (sure, if you adda Siemens HMI or SCADA and buy ProAgent on top, you can display motion monitoring events, but I wouldn't call this a trace and it requires a fair bit of configuration effort on top). |

Hi Fritz, Dont know, but every time I install Step 7 professional I always find it lingering in my folder, though I never mind openning it. I sometime usesPLC -Analyzer Pro 5. Very simple tool and is compatible with many PLC's. [IMG]/tf/WW/en/postattachments/download?attachmentId=30866[/IMG] I think Siemens shall do something to make PDIAG much more user friendly. |

New question published by Pingu is split to a separate thread with the subject How to use S7-PDIAG to trace I/O, memory, DB or anything as graphics a.k.a create trend?. Best regards |
