Ethernet diagnostics access: No access after repeated uncontrolled interruption of communication (corrected from V01.03.07)

Corrected from:
i950 servo inverter:  FW as of V01.03.07.1252

Response of the new version:
In the case of an uncontrolled interruption of communication, any open diagnostics access in the i950 will be automatically closed after two minutes of inactivity.
A new connection can now be reestablished immediately. In extreme cases, only after two minutes.


What happens?
Under certain conditions, communication cannot be established via the Ethernet diagnostics access. 
 
When does this behaviour occur?
The behaviour occurs when communicating via the Ethernet diagnostics access and the connection is not 'properly' closed when communication is terminated. 
This may e.g. be the case when the cable connection is interrupted or in the event of an exception with the client. In this case, the open diagnostics connections in the i950 will not be automatically closed. If this happens several times, all five permitted connections may remain occupied and a new connection can no longer be established.
 
Which products are affected?

i950 servo inverter: FW

Short-term measures:
Restart the i950 via the restart command or by switching the mains.
