(6) Cautions when setting a remote password
(a) If the starting I/O No. is changed after the remote password is set, the
previous remote password set with the Ethernet module/serial
communication module becomes invalid.
(b) Only the remote password set for the directly connected module can be
canceled (unlocked) by remote operation of GX Developer. (The remote
password for the indirectly connected module cannot be canceled by
remote operation.)
