On the subject of SIMATIC WinCC FDA, the White Paper

"Compliance Response 21 CFR Part 11 SIMATIC WinCC V6.0"

is available in English. Editions in German and French will follow shortly. The White Paper can be downloaded at www.siemens.de/wincc - FDA Compliance.

Available Option Packages

As already announced, the following WinCC options are available for FDA conformity:

1) SIMATIC Logon Service 6ES7 658-7BX11-2YA0

2) WinCC/Audit RT 6AV6 371-1DV06-0AX0

3) WinCC/Audit RC 6AV6 371-1DV16-0AX0

Daylight Saving Time Changeover

At the last changeover from summer to winter time (Fall 2003), inconsistencies occurred with WinCC V6.0 SP1 when displaying trends during the changeover period (1h). The data of the tags, however, is stored correctly in the archive. Since the proper display of historical data is of special interest - in particular for FDA customers - we would like to inform you that the display of the trends during the changeover period can be corrected with WinCC V6.0 SP2 - 2Q/2004.

These inconsistencies do not affect the changeover from winter to summer time (Spring 2004).
