Error and System Messages
Appendix B
B-6
Message Description
CANNOT COPY The requested copying task cannot be performed due to an internal problem in the file or RAM
disk. Contact Allen-Bradley customer support service.
CANNOT DELETE - OPEN PROGRAM The selected program is either active or open for editing and cannot be deleted.
CANNOT DELETE ALL PROGRAMS An attempt was made to delete all part programs or to reformat RAM while a program was being
edited or was currently selected as the active program for execution.
CANNOT DELETE PROGRAM The file selected cannot be deleted. This is caused by a major error being detected in the actual
software file of the program. It may be necessary to “REFORMAT”RAM to remove the
program. If this is unsuccessful, contact Allen-Bradley customer support service.
CANNOT DIVIDE BY ZERO An attempt was made to divide a quantity by zero, either using the CALC functions or in an
executing program with a paramacro operator.
CANNOT EDIT -- FILE UPLOADING The file you’ve tried to open is already open and is in the middle of a part program upload or
download operation with ODS.
CANNOT EDIT - MUST BE IN CYCLE OR E-STOP An attempt was made to edit a part program while another part program was currently being
executed.
CANNOT EDIT - OPEN PROGRAM The program that you have selected for editing is currently open for another feature.
CANNOT EDIT - OTHER FILE IS BEING EDITED An attempt was made to edit a part program while another part program was currently being
edited.
CANNOT EDIT ACTIVE PROGRAM An attempt was made to edit a program that is currently selected as the active program for
execution. Before it can be edited, the program must first be disabled.
CANNOT EXIT IN CYCLE You cannot exit in the middle of a roughing cycle because it executes at runtime, not during
setup.
CANNOT FIND CORRECT POSITION The program-restart feature cannot locate the correct program block in the program at which
automatic execution was interrupted. To position the program at the correct block, it will be
necessary to perform one of the other search operations. The operator must know what this
correct block is as the control has failed its recover operation.
CANNOT FIND PAL PAGE PAL requested a PAL display page to be displayed that does not exist in the display page file.
CANNOT FORMAT - OPEN PROGRAM A program was selected for automatic execution or was still in the edit mode when a request to
format memory was made. The active program must be disabled by pressing the {CANCEL
PRGRAM} softkey, and any program being edited must be closed by pressing the {EXIT
EDITOR} softkey before formatting memory.
CANNOT FORMAT RAM PARTITION The control is unable to format memory due to open file conditions indicating a more serious
problem. Consult Allen-Bradley customer support services.
CANNOT JOG -- ALL AXES ARE PARKED An attempt was made to jog a dual group when all the axes were parked.
CANNOT MERGE WITH SAME PROGRAM An attempt was made to merge the same program that is being edited with itself. If this is
desirable, first copy the original program, then merge the copy into the original.
CANNOT OPEN DIRECTORY This indicates a serious RAM disk problem. If retry doesn’t work, you may have to reformat.
CANNOT OPEN PROGRAM FOR READ This indicates a serious problem with the program. If retry doesn’t work, you may have to delete
the program.
CANNOT OPEN PROGRAM FOR WRITE An error occurred while attempting to open a file on the RAM disk. Either the RAM disk is full, or
there is an internal problem with the file. The file may need to be deleted.
CANNOT OPEN SUBPROGRAM An attempt to call a sub-program has failed. This is usually caused by the sub-program name
(programmed in the calling block with a P-word) not existing in the current program directory.
CANNOT READ A WRITE-ONLY PARAMETER An attempt was made to use the value of a paramacro system parameter that is a write-only
parameter. This parameter may have only its value written to. It cannot be read.
CANNOT READ DIRECTORY This indicates a serious RAM disk problem. If retry doesn’t work, you may have to reformat.
CANNOT READ PROGRAM This indicates a serious problem with the program. If retry doesn’t work, you may have to delete
the program.
