QUESTION:
What is the reason for an error message like: "Out of memory"
while reading large WinCC-Projects (> 60MB) using the WinCC
Configuration Tool?
ANSWER:
This message is based on a system characteristic of Microsoft
Excel.
Microsoft Excel does limit the RAM capacity provided for the
work folders. This limitation is about 60MB for Microsoft Excel
2000. For Microsoft Excel XP, the limitation was raised to
ca. 160MB.
While reading in large WinCC projects with theWinCC Configuration
Tool, this limitation might be reached. In this case, Excel
triggers out a simple Messagebox "Out of memory".
Raising the RAM provided by the PC for the work storage does not
solve the problem.
Note:
Please note, that large WinCC Projects under Microsoft Excel XP can
only be successfully read with the WinCC Configuration Tool,
once WinCC V5.1 Hotfix 3 had been installed.
