UPLOAD
DENIED,
DECOMPILER
ERRORS The ladder program stored in the processor contains errors.
The HHT cannot load this program into its memory. If the HHT
is unable to recover its existing program, it initializes to a
default program.
Downloading an error free ladder program to the processor
then uploading that program to the HHT.
UPLOAD
The HHT does not have enough memory to store this ladder
file or program.
Decreasing the size of the program.
DENIED, OUT OF
MEMORY
The programming device does not have enough memory to
compile the current user program. Aborting the procedure or shortening the current user
program.
UPLOAD
PROGRAM TO
SAVE DATA
EDITS
The program data changes you have entered are stored only
in the processor program. If you wish to save the data
changes in the HHT, you must upload the program.
Uploading the ladder program to the HHT.
WARNING:
PRG
REFERNCES
UNDEFINED
You are attempting to delete a rack or reduce the slot size of a
rack where the ladder program indicates there are input or
output instructions referencing slots in this rack.
Removing or changing the addresses in your ladder program
or aborting the procedure.
You are attempting to accept an instruction where the I/O
address has not been configured in your program.
Configuring the I/O slot for that address.
WARNING:
UNDEFINED I/O
REFERENCED
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.
The address you entered while editing does not match the I/O
configuration. Either changing the address to agree with the configured I/O
modules or exiting the edit mode and re–configuring the I/O to
match the entered address.
