Precautions - Mitsubishi L02CPU User Manual

Precautions

(1) When a remote password is set for UDP connections
• Determine the external device to communicate with and exchange the data. (The communication target
needs to be determined because, after unlocking of the remote password, communication is available with
any other devices.)
• At the end of data communication, always lock the remote password. (If the lock processing is not
performed, the unlock state is held until a timeout occurs. No communication for 10 minutes causes a
timeout, and the CPU module automatically performs lock processing.)
To prevent unauthorized access using the remote password setting, it is recommended to set all connection
protocols to TCP/IP and disable direct connection with the parameter.
(2) When a TCP/IP connection is closed before lock processing
The CPU module automatically performs lock processing.
