Access permitted/prohibited processing operation

external device.
■Access permit processing (Unlock processing)
The external device trying to communicate unlocks the remote password set for the connected Motion module.
If the password is not unlocked, the Motion module to which the external device is connected prohibits access, so an error
occurs in the external device.
The unlocking methods are shown below.
• SLMP dedicated command (Remote Password Unlock)
• Input password from engineering tool
■Access processing
Access to the specified station is possible when the remote password is correctly unlocked. Execute the arbitrary access.
■Access prohibit processing (Lock processing)
When access to the specified station ends, lock the remote password from the external device to disable subsequent access.
The locking methods are shown below.
• SLMP dedicated command (Remote Password Lock)
