Is it possible to have a binding to, and transfer a value to a variable that have the backup flag set?

Issue

The customer wants to have a binding and transfer a value, but also wants to have backup set on the receiving variable in the TAC Xenta device.

Environment

TAC Vista
TAC Xenta 280/300/401

Cause

Setting the Backup flag will make the variable be written into the flash memory every time the value is written.

Doing this on a value that is regularly transferred will damage the flash memory, as it has to write all the time.

Resolution

The Backup flag should not be set on variables that are written to on a regular basis.
