HHT Messages and Error Definitions
A–4
Message: Respond by: Appears when:
INVALID
OPERAND
The address entered is not a valid data file operand. Entering a valid address.
INVALID
PROCESSOR
TYPE This processor type is incompatible with your present ladder
program. There are references to inputs and outputs in your
program which do not exist in this processor type.
Choosing a different processor type or modifying your ladder
program.
INVALID
PROCESSOR
TYPE, HSC
PRESENT
This processor type does not allow HSC instructions. Removing any HSC instructions in your ladder program.
KEYPAD TEST
FAILED The internal test of the keypad has determined that there are
one or more inoperable keys.
Contacting your A–B service representative.
LABEL (LBL)
DOES NOT EXIST
FOR JUMP (JMP)
The JMP instruction does not have a valid LBL destination. Correcting the ladder program.
LABEL (LBL)
VALUE IS NOT
UNIQUE
The LBL number is assigned elsewhere in the ladder program. Choosing a different LBL number.
LENGTH IS TOO
LARGE The operand of the instruction is larger than what is defined as
valid.
Entering a smaller length.
MASTER
CONTROL
RESETS (MCR)
NOT MATCHED
A beginning MCR instruction is missing an end MCR
instruction.
Programming the required end MCR instruction.
MCR IS NOT
ONLY
INSTRUCTION
ON RUNG
An end MCR instruction is not the only instruction in the rung. Removing the other instructions in that rung.
MISSING
DESTINATION
There is an internal compiler error. Contacting your A–B service representative.
MODULE ID
CODE NOT
SUPPORTED
When you are configuring I/O and the HHT is unable to find a
slot configuration which matches this ID number.
Entering a valid ID number.
MULTIPLE OSR
INSTRUCTIONS When you attempt to enter multiple OSR instructions in a rung.
Only one OSR instruction per rung is allowed for a 500 or 5/01.
Aborting the entry.
MUST SELECT
AN
INSTRUCTION You attempt to accept a rung without instructions. A ladder
rung must contain at least one output instruction to be
accepted.
Entering output instructions or aborting the rung edit.
NO MEMORY
MODULE
You are trying to copy a processor RAM ladder program to a
memory module (EEPROM) that is not installed in the
processor.
Installing the memory module.
NO RESPONSE
FROM
PROCESSOR
The processor is not answering requests from the HHT to
communicate.
Checking power and communication connections to the HHT
and processor. Also check online configuration such as baud
rate and the number of devices on the network.
NO SLOTS
AVAILABLE You are attempting to define more slots than are physically
available in this rack.
Aborting the procedure.
NO SUCH
SUBROUTINE
FILE
The subroutine number in the JSR instruction does not exist.
Creating the subroutine or changing the number in the JSR
instruction.
NOT A BIT The address entered does not specify a legal bit in a data file. Entering a valid bit address.
