5.6 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 in Automation PCs and Panel PCs.
This can result in one of the two cards not being detected during system startup. This is caused by varying
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 limits of the time
frame provided for startup. This can occur because the startup time for the CompactFlash cards fluctuates
due to the variance of the components being used. Depending on the CompactFlash cards being used,
this error may occur never, sometimes or always.
