Tag Group Configuration - Write Only Tags

Hi All,

We’re working on an Ignition 8 project with a large number of tags and trying to configure tag groups in the most performant way possible. We have ~25,000 tags which are for lack of a better term ‘write only’. They are commands in a PLC where the feedback is a different address. Thus we don’t need these tags scanned at all from a Vision/Historian/Alarming perspective - just need to be able to write to them (using system.tag.writeBlocking only) on demand.

Does anyone have any configuration tips for us?

Thanks,
Pete

It sounds like you don’t need tags at all. Maybe system.opc.writeValues would accomplish your goal without the overhead of tags.

Great suggestion! We will investigate that. Thank you!
