Runtime may close unexpectedly with rated redundancy under specific circumstances

Runtime may close unexpectedly with rated redundancy under specific circumstances

Summary

The zenon runtime on the primary server may close unexpectedly in a configuration where a project uses rated redundancy with a (internal) variable used in the calculation for the rating, when changes to the variable limit or reaction matrix are made and these changes are compiled, transferred and reloaded, and the value for this changed variable changes in the runtime. The runtime on the secondary server will take over after detection of the loss of the primary server.

Description

The zenon runtime on the primary server may close unexpectedly in a configuration where a project uses rated redundancy with a (internal) variable used in the calculation for the rating, when changes to the variable limit or reaction matrix are made and these changes are compiled, transferred and reloaded, and the value for this changed variable changes in the runtime. The runtime on the secondary server will take over after detection of the loss of the primary server.

Solution

An issue has been addressed in the runtime where after a reload of changes made to a variable used in the rating calculation, the Runtime on the primary server could close unexpectedly when the value of this variable was modified.
