When the keyword has been registered, the built-in PLC function parameters,
main program and comments cannot be read/written from the built-in PLC
function to the GX Developer device unless the keyword registered to the built-in
PLC function is entered.
(2) Registration and cancel of keyword
A keyword of up to six digits can be set in hexadecimal (0 to 9, A to F).

at the same time, apply a lock to reading/writing of the ladder program by registering a
keyword.
