Hi teteph56! AlarmS messeges are not of the more type of messages which are polled cyclic by the panel on the PLC. AlarmS are a pushed telegramfrom the PLC meaning as long as there is no alarm there is no telegram sent. This have sometimes an adavatage the alarms aretimestamped in the PLC so the chanses of seeing an orgin of error is higher (if an error couses 3 alarms a correct time stamp will show which alarm was first). Also theese messages are "ackowledged" by the panel mening if you have no communication you will still get the messages once communication is restered (within limits depending on the plc 1000 'nds of messages can not be buffered.) Check this FAQ if your intrested http://support.automation.siemens.com/WW/view/en/24013249 To you problem I agree try rebuild all and maybe disable delta download if that wont work please answer this: The error does it occure once your project is downloaded? If you unplug the communication does it go away? What happends if you change adress of the panel IP MPI or DP adress (easiest way would e from the control panel of the panel)? Zeb |
