Just a quick query to all,
On site we use WinCC 2008 for HMI screens, some of the code has been written by other engineers and to determine the cause of some of the faults i take the alarm text, cross reference this in WinCC and look for the 'trigger address'. Most times i find a numeric address, for example - DB0.DBX0.0 but other times i find a 'trigger address' that looks like DB[text...] DBW0
I was wondering if there was a way somebody could explain to me why this is the case? as well as how to cross reference this easier between the HMI and PLC.
I hope this makes sense, i have attached a screenshot of this as well.
My apologies if this has already been asked on the forum but i do not have the ability to search prior to posting.
Thanks in advance.
