hi,

if you scroll down you will find:

Enhancement of the user experience:

The following behavior has been improved:

• The sporadic behavior that, in case of a TC connection which is aborted by the remote station, the CPU loses the data sent by the remote station, does no longer occur.  (The different RST/FIN behavior shown with TCP connections has been adjusted here.)
• As documented in the manual, the master value for the cross-CPU Motion Control axis control  can now be provided by all SIMATIC S7-1500 CPUs.
  
  

The following behavior was corrected:

• It does no longer occur that, after power off/on, the CPU goes to STOP with the message  "Warning regarding remanent data: Remanent data lost - Current CUP operating state: STOP (initialization)", and data being marked as remanent get lost if more than 1020 data block data are declared as remanent.

• The following message is no longer output sporadically: "Severe firmware exception error (internal system code: 16#00000000 16#10020000 16#00000000) CPU changes to the DEFECTIVE STATE (system reaction)“ if - in case of an adjustment of the initial values of a DB without structural change of the content, or in case of changes to the CPU message list and subsequent download - the connection has been aborted in combination with Motion and F-applicatio3s.

• The following message is no longer output sporadically: "Severe firmware exception error (internal system code: 16#00400001 16#10020082 16#77A2A4D4) CPU goes into the DEFECTIVE state (system reaction)“ when the OPC UA Client does not behave in accordance with the OPC UA specification upon the termination of subscriptions.

• The following message is no longer output sporadically: "Severe firmware exception error (internal system code: 16#00400001 16#1002003A 16#00010246) CPU goes into the DEFECTIVE state (system reaction)“ when the OPC UA Client on the S7-1500 CPU tries to read a variable which has not been created in accordance with the OPC UA specification as instance of an abstract data type on the OPC UA Server.

For S7-1500 T CPUs only:

• With an interpolated linear movement, the command is always terminated as soon as the target is reached.
