SNVT on FB Program
StruxureWare Building Operation site
When you create a SNVT in a functional block and you copy it for a new one and after you rename the copied SNVT, When you commissioning the local node with a LNS tool the node keeps the first name.
The SNVT (Standard Network Variable Types) copy issue exists. Where it is happening is that the XIF file in the device is not getting updated when the signal name changes. An LNS management tool will upload this XIF file and use it to see the values. This has been reported as bug in software and will be resolved in an upcoming release.
