8. Known problems / issues
The following issue for the PPC800 devices is known:
•
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. The problem described above 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 might never, sometimes or
always occur.
•
During daisy chain operation of multiple AP800/AP900 devices via SDL, it's possible that
the touch controller status shows a red "X" in the Control Center applet for the touch
screen driver when the touch controller is detected. The functionality of the touch system
is not affected by this. This can be avoided by setting a panel locking time of 50 ms. The
panel locking time can be configured with the B&R Key Editor.
