Precautions
The following section lists the precautions for using remote password.
■Set connection
Set the remote password for the connection used for data communication with an external device that can execute the unlock/
lock processing.
■When remote password is set for UDP/IP connection
• Determine the external device to communicate with and perform data communication. (With UDP/IP, after the remote
password is unlocked, data can be exchanged with devices other than the unlocked external device too. Determine the
communication destination before starting use.)
• Always lock the remote password after data communication is finished. (If the remote password is not locked, the unlocked
state is held until timeout occurs.)
■TCP/IP close processing
If the TCP/IP is closed before the TCP/IP is locked, the CPU module will automatically start the lock processing.
■Remote password valid range
The remote password is valid only for access from the Motion module for which the parameters are set. When using multiple
CPU modules in a multiple CPU system, set a remote password for each CPU module for requiring a remote password.
