File password
(*1) After FB which has a block password and sequence program which has a function are written to the CNC, when the
sequence program is read with the simple project (without labels), the area where the block password is set is read as
an actual ladder (ladder with labels and functional block compiled). To read a ladder with labels and functional blocks,
set a file password.
(*2) Symbols that can be used in a block password are as follows:
! " # $ % & ' ( ) * + , - . / : ; < = > ? @ [ \ ] ~
Do not use the symbols "@", "^", "`", and "|" because they may not be input with PLC on-board although they can be set
with GX Works2.
