Inactivity Time | The inactivity time specifies the interval after which | Modifiable |
| the connection is terminated if no sign of life is |
|
| received from the partner |
|

|
Window Time | The window time specifies the interval at which sign | Display only |
| of life frames are sent. For SIMATIC NET CPs, the |
|
| window time is set to 1/3 of the inactivity time |
|
| s, default 10 s). Sign of life frames are sent to check |

Notice
Window Time and Inactivity Time
The partner responds to a sign of life frame with a frame. They are therefore sent to the partner at the intervals of the window time. To avoid unwanted connection termination, the inactivity time should be at least three times as long as the window time.
