Improvements to old functions and bug fixes

The following behavior has been improved

• The variable <to>.FollowingError.AdditionalSetpointDelayTime affects the calculation of the following error (<to>.StatusPositioning.FollowingError), as well as the corresponding error reactions
• Improved stability for R/H CPUs during the transition from the SYNCUP operating state to RUN-Redundant (catching up with the backup CPU) and simultaneous failure/stop of the primary controller</to></to>

The following behavior has been fixed

• R/H systems: When acknowledging alarms after a primary-backup switchover, the system remains in the RUN-Redundant state
• The sporadic error message no longer appears when observing "L STW" instructions in AWL:

1. temporary CPU error: fatal firmware exception error (internal system code: 16#00400001 16#1002004B 16#00000000) CPU changes to DEFECTIVE state (system response)

• When calling an OPC UA method that is currently not executable and contains structured data, the sporadic error message no longer occurs:

1. temporary CPU error: fatal firmware exception error (internal system code: 16#0FFF0000 16#10020000 16#00000000) CPU changes to DEFECTIVE state (system response)

• When using SFC "WWW" to synchronize user-defined web pages with the user program in the CPU, the sporadic error message no longer occurs when writing variables via AWP command on an otherwise empty web page:

1. temporary CPU error: fatal firmware exception error (internal system code: 16#0FFF0000 16#10020000 16#000000000) CPU changes to DEFECTIVE state (system response).

• When an NTP server returns and a syslog server cannot be reached at the same time, the error message no longer appears in a highly-sporadic manner:

1. temporary CPU error: fatal firmware exception error (internal system code: 16#00100001 16#1002FFFF 16#00000000) CPU changes to DEFECTIVE state (system response)
