Dear,

Can the logix driver read the extended properties of a tag into a compactlogix/contrologix?

Regards

Arnaud

Only Factorytalk can read extended properties (.@description etc) from Logix controllers.

I think you might be able to move extended properties into its own tag on the PLC though, which then would be available via OPC

I don’t think so. Let us know though. 🙂

Hi Everyone,

Thanks for your reply.

Here is an update.  
Like @neil2 say (By the way, welcome on the forum), the logix driver of ignition doesn't support the read of extended tag properties.  
@kelly.draehn, i've just tried and you cannot put a tag extended properties into another tag value.  
To solve my problem there is two solution:

- Use the extended properties on the ignition tag
- Use memory tag in ignition to store my information.  
I've choose for the second one.

Regards

Arnaud
