HHT Messages and Error Definitions
A–2
Message: Respond by: Appears when:
DATA FORCES IN
LAST STATE,
The instruction or rung you are attempting to delete may
contain the only reference to a data location. Answering YES if you want to continue the deletion.
Answering NO if you wish to abort the deletion.
LAST STATE,
DELETE?
Forces are present on the instruction or in the rung you are
attempting to delete. Answering YES if you want to continue the deletion.
Answering NO if you wish to abort the deletion.
DATA INTEGRITY
TEST FAILED The ladder program file stored in the HHT RAM is lost. The
HHT battery may be missing or the voltage is low.
Connecting or replacing the battery.
DEFAULT FILE IN
PROCESSOR
The processor contains a default ladder program. Downloading a non–default ladder program.
DELETED RUNG
BUFFER EMPTY
You undelete a rung and the rung buffer is empty. No response.
DESTRUCTIVE
RAM TEST
FAILED
The battery–backed RAM chip of the HHT is corrupted. Contacting your A–B service representative.
DIRECTORY FILE
CORRUPTED The ladder program file directory of the processor is
inaccurate. No response. The HHT is unable to read or monitor this
program.
DOWNLOAD
DENIED,
COMPILER
ERRORS
The ladder program has been saved with errors (possibly I/O
configuration errors).
Using the ladder program editor to correct your program.
DUPLICATE
‘(HIGH SPEED
COUNTER)’
INSTRUCTION
You attempt to program multiple HSC instructions. Your ladder
program is allowed to contain only one HSC instruction
(processor must be DC type).
Removing duplicate HSC instructions.
ERROR
EXPANDING THE
DATA TABLE
The length parameter of an instruction is trying to create a
data file larger than 256 elements.
Entering a smaller length.
ERROR: INVALID
FORCE
The cursored instruction is not an input or output instruction.
Choosing the correct type of instruction or abandoning this
attempt.
ERROR:
UNDEFINED I/O
ADDRESS
A mismatch exists between the I/O addresses used in the
ladder program and the configured I/O modules.
Either editing the program and changing the address to agree
with the configured I/O modules, or re–configuring the I/O to
match the entered address. For the latter, refer to chapter 4
for more help. Important: You can SAVE the program with
errors (to correct at a later time), but you cannot download the
program to the processor.
FILE CANNOT BE
CREATED You are creating a ladder program file where the number
entered is illegal or the file already exists.
Choosing a different file number.
FILE CANNOT BE
DELETED
The entered program or data file number does not exist or is
incorrect.
Important: Data File numbers 0, 1, and 2 and program files 0
and 1 cannot be deleted.
Choosing a different file or aborting the procedure.
FILE
OVERWRITE
ERROR
A file overwrite has occurred. SQO, SQC, BSL, BSR, FLL, or
COP instruction operation has crossed file boundaries.
Correcting the file length in the appropriate instruction.
HSC ALREADY
EXISTS
You attempt to program multiple HSC instructions. Your ladder
program is allowed to contain only one HSC instruction
(processor must be DC type).
Remove duplicate HSC instructions.
