Fault Legend Description
A 10 Divide By
Zero An attempt was made to use ‘0’
as a divisor during computation. No Yes Yes Minor Software used to create the application program
may have been old. (Earlier Kernel and library
versions exhibited this problem.) Check the
application program for use of zero during
division.
B 11 Result
Underflow Floating point error: 1) a
computation is smaller than the
smallest quantity the CPU can
store; 2) An error condition
occurred when an item was
called from an empty stack. No Yes Yes Minor Minor Check the application program for use of
extremely large and/or small numbers for
computation.
C 12 Result
Overflow Floating point error: An error
occurred when calculated data
could not fit within the
designated field. No Yes Yes Minor Minor Check the application program for use of
extremely large and/or small numbers for
computation.
D 13 Invalid Result Floating point error: Computed
result is incorrect or is not within
bounds. No Yes Yes Minor Minor Check the application program for use of
extremely large and/or small numbers for
computation.
E 14 Bad Address
Mode Operand address mode is not
recognized. Examples of correct
addressing is Direct and Indirect. Yes Yes Yes Major Major Verify that there are no hardware problems on
the PC used to create the application. Re-
compile and reload the program and reload it to
the SmartTrac drive. The Smart Trac main CPU
card may be faulty. If available, download a
small test program to see if fault persists.
