   Show release notes Hide release notes

   < New functions >

   • The “LINK LOSS DETECT” function has been added to improve connection stability in systems that ​use the Telnet protocol.

   This function detects disconnected network cables or lost communication links and automatically releases the connections to the affected external controllers.

   [ NOTE ]

   • Ping responses are used for detection.
   • Depending on the firewall settings of the external controller, it may not accept pings and interpret this as a network disconnection, causing the Telnet connection to be terminated.
   • In this case, either turn off the LINK LOSS DETECT function or enable ICMP Echo Request in the firewall settings.
   • For detailed information on the functions and how to set them up, please refer to "Owner's Manual Addendum V2.17".
