Appendix A
This appendix describes the error messages displayed by the Keypad
Module. It also lists the display characters and their corresponding
hexadecimal values as an aid.
The following list shows error messages and their explanations. Items with
the bullet (
•
) in the left margin are messages that refer to hardware or
software faults that cannot be corrected by programming or changing the
configuration settings.
•
SYSTEM ERROR
A hardware failure has been detected on the Numeric Keypad Module.
•
EPROM CRC ERROR
This error indicates that the power up diagnostics have detected a CRC
error while testing the EPROM memory of the Numeric Keypad Node
Module.
•
INTERNAL RAM ERR
This error indicates that the power up diagnostics have detected an error
in the RAM contained on the module’s CPU processor.
•
EXTERNAL RAM ERROR
This error indicates that the power up diagnostics have detected an error
in the RAM that is external to the module’s CPU processor.
•
INT/TIMER1 ERROR
This error indicates that the power up diagnostics have detected an error
with the interrupt/timer circuitry.
DATA TYPE ERROR
This error indicates that the data type set up is incompatible with the other
DIP switch selections.
RACK CONFIG ERR
This error indicates a rack configuration error, i.e. (address switches, data
type, SMD enabled). This is caused by incorrect setting of DIP switches
on the module.
COMM SETUP ERR
This error indicates that there was an error during the setup of
communications.
COMM START ERROR
This error indicates that an error was detected when the Numeric Keypad
Module attempted to start communications.
