T5BusEIPS: Idle TCP connections are not automatically closed.

T5BusEIPS: Idle TCP connections are not automatically closed.

Description

The EtherNet/IP Adapter (T5BusEIPS ) does not close TCP connections when these are idle and do not send any data. This can lead to a denial of service for valid EtherNet/IP Adapter when the maximum number of 124 TCP connections are used by (other) non-EtherNet/IP clients.

The issue has been addressed. The EtherNet/IP Adapter (T5BusEIPS) provides a new configuration option "Inactivity Timeout (s)" to automatically close idle TCP connections on port 44818. By default, the inactivity timeout is disabled with a value of -1. When a timeout value >0 is configured, the oldest TCP connection on which no data was received is closed after the timeout time, when reaching  the maximum limit of 124 TCP connections.
 
To benefit from this fix: 
  • Update your zenon Software Platform to the latest build of zenon 12 or higher.
