Thank you for the reply. The thread makes interesting reading.
Ideally though I don’t really want to restart the gateway if I can help it.
Also, my tags are saying “CONFIG ERROR”, not “BAD QUALITY”.
As an example [CoolTower]DB60,X0.0 does not work but [CoolTower]DB90,X0.0 does!
I tried just restarting the Siemens Driver Module. No difference.
I tried deleting the device, restarting the module, recreating the device. No difference.
Also when recreating (or enabling) the device it can take a minute or more to actually go to state Connected.
I then tried creating a 2nd device (different name) but pointing to the same PLC. This connected within seconds.
I then tried one of the troublesome addresses. It worked.
So maybe somewhere within the system there is some bad/corrupt info relating to the CoolTower device name?
If I create a 2nd device CoolTowers instead of CoolTower then I need to go and update the OPC path for every tag for that PLC.
I guess I could export the whole tag database, do a find/replace then reimport.
But I also wondered if there was a way to do it directly on Ignition’s internal database?
In the Raw Settings bit under console?
Remember I’m on version 7.6.
Any thoughts? Or do I need to go directly to support for this?
