They should not influence the statistical counters ("turbine OK" still increments after the faults occur) and do not effect the behavior of the turbine. -Garth ---------------------- Forwarded by Garth Ripton/EWC/Enron on 06/07/2002 11:09 AM --------------------------- From: Gert Torbohm@TWTDE on 06/07/2002 02:58 PM CED To: Garth Ripton/EWC/Enron@ENRON cc: Andre Riesberg/DEVELOP/TWT/DE@TWTDE, Detlef Menke/DEVELOP/TWT/DE@TWTDE, Till Hoffmann/DEVELOP/TWT/DE@TWTDE, Clemens W"ste/DEVELOP/TWT/DE@TWTDE Subject: Antwort: Undocumented fault messages Hi Garth, we don't know the reason for these 'fault' appearances, yet. It has to do with the communication between PC and PLC. But : it did not influence the status of the turbine, neither it shuts down, nor downtime counts up. In version 1x629 the solve the problem, but the real cause is not solves, until now. Clemens will work on it. What's the time schedule for updating V1x629 ? Best regards and nice weekend Gert.

There are a number of "undocumented" fault/status messages that are logged frequently: "EM247" 102 times "EM242" 102 times "EM238" 101 times "EM237" 101 times "EM235" 101 times "EM312" 56 times "EM280" 56 times "EM248" 56 times "EM304" 52 times "EM272" 52 times "EM311" 51 times "EM306" 51 times "EM302" 51 times "EM301" 51 times "EM299" 51 times "EM279" 51 times "EM274" 51 times "EM270" 51 times "EM240" 51 times "EM269" 50 times "EM267" 50 times Most of these fault were logged on turbine 5 and turbine 6 (with a few on turbine 7). They are not distributed between all the turbines but isolated on a few. The major question that that operations asked me was which production statistic timer was incremented when these conditions were logged. My guess is that since none of these stop the turbine that the "OK" timer continued to increment. Is this correct? The question that I have is: what is causing so many of these messages in the log? Do these status messages have any specific meaning? According to the documentation there are only about 220 messages that have descriptions in the error list data base (in VisuPro v1.27.0.0). Where are the other messages coming from? (This is version 13527 Bachmann software.) I think this issue was brought up several months ago but I don't think we got any additional information. Gru?, Garth
