NOTE
1 To encrypt programs, set parameter EIA (bit 4 of No.
0000) to 0 (to specify that the punch code is ISO).
2 An encrypted program cannot be registered as an
additional program ([READ]-[1_PROGRAM]-[ADD]).
3 Programs outside the security range cannot be input
from encrypted programs.
Program display
1 On the program directory screen, all program numbers are
displayed together with comments.
2 On the program text screen:
When the program memory is locked, programs within the
security range are not displayed.
When the program memory is unlocked, all the programs are
displayed.
The change from the unlocked state to the locked state or from the
locked state to the unlocked state is not applied to the display
immediately. The change takes effect when, for example, a
program search is performed.
Editing and deleting programs
When the program memory is locked, the programs within the security
range cannot be edited or deleted. When the program memory is locked,
an attempt to delete all programs results in only those programs outside
the security range being deleted.
Searching for programs
In the locked state, a program search is performed within the protected
range as described below.
1 When no program number is specified (by using [FRWRD
SEARCH] and [NEXT PRGRAM], for example), programs
within the protected range are skipped.
2 When a program number is specified for a program search within
the protected range (by using [FRWRD SEARCH], [PROG#],
program-number, and [EXEC], for example), and the search finds
a matching program, the program is selected. However, the
warning message "INVISIBLE PROGRAM" is displayed. On the
program text screen, the number of the matching program is
displayed as an O number. However, "PROGRAM NOT
FOUND" is displayed for the program contents.
