Troubleshoot the System Chapter 9
File System Errors The file system on PanelView Plus CE terminals is checked at startup
and errors are reported in a message box. Record the error
information and always elect to correct the problem. Typically, the
message box will reappear until the error is corrected.
File system errors are rare and can usually be corrected. The most
common cause of lost clusters and file/directory size mismatches
within a FAT file system is an unexpected power outage while writing
to the file system. Always stop applications before removing power so
that data is cleanly flushed out to the file system and the file system is
brought to an orderly stop.
Although the FactoryTalk View ME application runs from RAM,
applications such as data and event logging, and historical trending,
write to flash memory and should be stopped before removing power.
Advanced Diagnostics for
CE Terminals Ping and ipconfig are invaluable for network debugging along with
some knowledge of IP and the Winsock error codes.
•
Try to ping the destination host.
•
Check the destination address.
•
Check whether you have a router configured in your network
system (your WinSock implementation).
•
Use the tracert command at the command prompt on the
desktop to try and determine where the failure occurs along the
route between your host and the destination host.
•
Some utility programs are distributed on the Accessories CD.
Others can be developed using the software development kit
(SDK).
•
Take advantage of alternate connectivity - mouse versus touch
screen, keyboard versus keypad, serial communication, and
alternate Ethernet connections.
•
Enable the crash logger and examine the EXCEPTIONS.LOG file
from the PanelView Plus CE terminal when suspecting an
operating system or application crash.
•
Store the current operating system on an external CompactFlash
card. You can then use this card to update the terminal in case
the operating system is out-of-date or corrupted.
•
Store Autorun.exe utilities on an external CompactFlash card
that can be easily run by inserting the card in the external
CompactFlash card slot of the terminal.
•
Know useful keyboard shortcuts so that you can navigate
around the system without a mouse or touch screen.
