IEC850: TCP Keep alive is not sent when there is no data exchange

IEC850: TCP Keep alive is not sent when there is no data exchange

Description

Since TLS implementation, the IEC850 driver did not send TCP KEEP-ALIVE if no data exchange took place for 20s, but for period default by the Operating System (in Windows about 2h). 
The issue has been addressed and the TCP KEEP-ALIVE timing works as defined by the IEC 61850 standard.

To benefit from this fix: 
  • Update your zenon Software Platform to the latest build of zenon 11 or higher.
