Note The buzzer will beep when the Set–Not–Reset Keys are pressed to warn that
Either the entire program area and/or designated data areas can be deleted, or a
specified range of the user program area can be deleted. When 0 is specified,
either all or none of the program area must be cleared; a specified range cannot
be cleared. When the entire program area is cleared, the program type will set to
“ladder only” and will need to be changed to use SFC programming. Even
though the entire program is cleared, an END(001) instruction is automatically
generated.
Press the NOT Key to clear only data areas without clearing the program area.
The data areas that are displayed will be cleared. If there are any data areas that
should not be cleared, input the data area abbreviation to delete the display for
that area. Specify the EM bank by using the 0 to 7 Keys.
To clear a specified range, specify “1” and the start and end addresses. Do not
set an address larger than the address that contains the END(001) instruction or
an error will result and “Address too high” will be displayed. If the END(001)
instruction is cleared, a program error will result if the user continues operation
without adding an END(001) instruction.
The user’s program will be cleared even if the UM is protected via Programming
Device settings, but will not be cleared if it is protected with the key switch on the
CPU Unit and “Read only” will be displayed.
Refer to Appendix D Inputs for Instructions and Operands for the key sequences
to specify instructions and operands.
memory will be cleared if you continue with the operation. It is not an indication of
an error in operation.
