How to handle OPC offline conenction

Hi All,

What is best practice to handle opc connectivity being offline?

We have several opc connections dedicated machines that when turned off (intentionally). Our logs get overwhelmed with messages about OPC Connectivity errors and tags that can't connect.

I'm curious about your best practice for managing these messages?

I don't want to eliminate all messages, just manage the Quantity and Frequency.

I was thinking of a Driven Tag Group that is conditioned on the OPC Connectivity.

Please share your thoughts.

I'm running Ignition 8.1.53

Thank you in advance

I've done this. It will cut down on spam logs for sure, but I have not checked on any performance gains. It would depend on the number of tags and polling rates.

You would do it just like you described, use a boolean tag as a trigger to switch between a fast rate and a slow rate in the tag group.

I'm not aware of any other options.
