4.6 Known problems/issues
The following is a known issue for devices with two CompactFlash slots:
•
Using two different types of CompactFlash cards can cause problems with Automation PCs and Panel
PCs. For example, it is possible that one of the two cards is not detected during system startup. This is
caused by different startup speeds. CompactFlash cards with older technology require significantly more
time during system startup than CompactFlash cards with newer technology. This behavior occurs near
the end of the time frame provided for startup. The problem described can occur because the startup time
for the CompactFlash cards fluctuates due to the different components being used. Depending on the
CompactFlash card being used, this error might never, sometimes or always occur.
