Description
The FSTP input on the
1134 COP board did
not pick up when
expected.
The FSTP input on the
1134 COP board did
not drop out up when
expected
Field Variables Backup
Init. Field variables
backed up for the first
time. Older software
did not backup the
field variables. When
new software replaces
the older software,
this error will be
displayed.
Field Variables Backup
Table Checksum Error.
The verification
checksum for the
backup field variable
table has failed.
During power outages
or brown-outs,
enough noise can be
generated on the 5V
DC supply to cause an
error in reading the
field variables table on
power up. For this
reason, we keep the
data in two separate
tables. If only one
table checksum error
occurs, then valid data
will be restored.
Section 6 – Main CPU Faults & Detailed Faults
Possible Cause/Suggested Fix
• Faulty FST1 output chip. Replace output chip.
• Faulty FSTI input chip. Replace input chip.
• Faulty FST1 output chip. Replace output chip.
• Faulty FSTI input chip. Replace input chip.
• If this error occurs every time the CPU powers up, then the
CPU may be faulty and should be replaced.
• No action is required.
