The part-protection clear operation clears part-protection set using the CVSS,
SSS, or SYSMAC-CPT. The same password that was used for the part-protect
operation must be used.
If there is an error, an error message will be displayed when the Write Key is
pressed. The following errors may occur.
Protect error: A protection error occurred when the user attempted to protect
user memory that has been already protected.
A protect error also occurs when the user has attempted to clear the protection of
the user’s memory but actually it was not protected.
Password error: A password error occurs when a wrong password was input to
clear the protection of the user’s memory that has been protected.
If one of the above errors occurs, press the Clear Key to return to the previous
display.
If the user’s memory is protected, programs cannot be read, written, or moni-
tored.
If the user should forget the password, the protection of the user’s memory can-
not be cleared. The only solution in this case is to clear the memory, which will
clear protection, and transfer a backup of the program to the Programming Con-
sole from a memory card or other source.
