Industrial Edge SIMATIC S7 Connector – Cannot save tag with valid absolute address (DB10.DBW0) on S7‑1500

0
I’m using Siemens Industrial Edge – SIMATIC S7 Connector with an S7‑1500, and I can’t save a tag even though the address syntax and all required fields are correct.DetailsPLC: S7‑1500Protocol: S7‑Protocol (S7‑300/400/1200/1500)Rack / Slot: 0 / 1Data source selected: Kittings410DB used: DB10 (Digiheta)Optimized access OFFAbsolute offsets visibleExample variable:Test1 : Int (offset 0.0) Tag configurationAddress: DB10.DBW0Data type: IntAcquisition: 5 seconds, CyclicContinuousAccess mode: ReadDespite this, the Address field remains red and Save stays disabled, with no clear error message.QuestionDoes the SIMATIC S7 Connector validate the DB address online against the selected PLC before saving? Will this fail if the selected data source does not actually contain DB10, even if the PLC is reachable and the address syntax is valid?

Hello,


If you are configuring the absolute address then you have to use the % before the adress please refer to this docuiment https://docs.industrial-operations-x.siemens.cloud/r/en-us/v2.3/simatic-s7-connector/limitations/limitations/configuring-tags-with-absolute-addresses


If you have any further questions don't hesitate to reach us


Thanks

Hi Utku,


Just to add some extra information. For me is really useful to use a watch table to check the Address in Tia Portal, and then to write it correctly on the common Configurator.


For example, on this case you can see I have this no Optimized DB:




And then if you create a Watch table you can check the Address.





As Bala and Cosmin said, you need to add this %

Hi,

This is not related to PLC or data source validation, but to the address format.

When using absolute addressing in the S7 Connector, you must add a % at the beginning. Without it, the field stays red and you can’t save it.

Try it like this:

%DB10.DBW0

This worked for me 🙂
