Hallo, what is the difference between acquisition and archiving cycle, in the information given in the WinCC Information System are not that clear. It states that
Is 1. related to process object (PO) reading of Tags in the pictures (if so, 2. is absolutely clear) or what is its purpose? What are the limitations of update upon change (archive and POs), I find only this
in WinCC -- Configuring Tag Logging -- Tag Logging performance. Is the consequence that in the case I want a minimum cycle of < 1s, that I have to change to the desired cycle regardless if the tag is changing within that cycle (occasionally). I've also checked the Siemens entry WinCC -- Configuring Tag Logging -- Archiving Tag Logging and its linked entries but couldn't find any further hints. In addition I have another question. |
