S7TIA: When a datapoint has a specific invalid symbolic address, this datapoint does not have INVALID bit in service Engine, but has SPONT bit although the value which is displayed in the service engine is not the correct one

S7TIA: When a datapoint has a specific invalid symbolic address, this datapoint does not have INVALID bit in service Engine, but has SPONT bit although the value which is displayed in the service engine is not the correct one

Description

If a S7TIA variable has a certain invalid symbolic address, this variable shows a SPONT bit instead of INVALID in the Service Engine in spite of incorrect symbolic addressing. This occurs mainly if the symbolic address contains ".Program.".

This behavior has been changed. The variable now correctly shows INVALID.

To benefit from this fix:

  • Update your zenon Software Platform to the latest build of zenon 8.20 or zenon 14 or higher.
