NOTE
Object code with a special password can be
decompiled without entering a password. In this
case, only a subprogram in the non-protection area
(P1500 or later) can be displayed, edited, and
printed. When compiled, [Setting of Password] in
the compile option is ignored and an object code is
created by using a special password added to the
object code. This enables only the non-protection
area to be changed while a ladder program created
by a machine tool builder is protected.
