Communications "Freshness"

[Lucifer]

Hi, I am programming some ATV9s on my M580 using Ecostruxure Control Expert and the Data Type automatically includes a "Freshness" BOOL (Global Freshness) and a "Freshness_1" BOOL (Freshness of object). I cant find anywhere that specifies what conditions these are monitoring. Can anyone point me to the relevant doco?

Each IP address defined in the Device List can have one or more "Requests" defined underneath it.  I understand Freshness to be the global health status of all requests, and Freshness_1 to be the health status of the first request, and Freshness_2 is the health status of the 2nd request.  Here is a device with two requests:

And it has Freshness_1 and Freshness_2:

If I remove the 2nd request, I only get Freshness_1.

I have never had an instance where the Freshness_1 and Freshness_2 where not the same as Freshness, but it could be possible if one of the requests is attempting to read an address which is not defined on the target device.

Here is a SE FAQ which partly explains it.

It is also in the ECE help if you search for Freshness_1.

Thanks Matthew, that was the info I was looking for.
