Hi,
I can remember there is somewhere in DeltaV folder an application to see current download status. Unfortunately I'm getting older and my memory is not so goo anymore. Anyone can help?

DeltaV Explorer will show you Download Needed status in the form of "Yes, No, or Unknown" For Yes, you would see a solid blue triangle next to the module in the hierarchy tree, under the controller/Assigned Modules container. For Unknown, you see a triangle with a question mark. and if No then no triangle.
Right click on the controller (with a blue triangle) and you can select Download Status:
Show Details will indicate the general area of change that is flagged, such as setup data, modules, but it does not give you module details such as what was changed. VCAT would be required to get that granularity in module changes.
Show Details will walk all "unknown" download statuses and will update the status, showing you the resulting affected Items.
Update will update the status and does not show you the details. Both will clear the unneeded flags, and leave solid blue triangles. When you see a solid blue triangle next to the controller, but no module is flagged, then the change needing download is in the setup data. Show Details will identify which setup file is flagged. This Show Details feature was introduced in v12 I think.
When you do a download, the content of that download is stored in the DownloadProgress.Log file mentioned by Stefan. This is the same content you see in the download dialog. Note that this file is replaced with every download. It is not preserved unless you make a copy for later review. When there are concurrent users on the system performing downloads, the file may be overwritten before you have a chance to open it or copy it. On an RDS server, all sessions share the same DVDATA folder. On workstations, each station has its own DVDATA folder. I haven't checked, but if the log is stored on the local computer that you are running Explorer or Control Studio, then you have control of when it is overwritten.
In earlier versions of DeltaV, an upload action would flag the Module as needing download. More recently, (v11?, v12?) the upload does not set the flag. Instead, the modified parameter values stored in the POWERUP directly will get downloaded automatically so that the controller restart files are updated, restoring the controller restart location to "Controller" and ensuring a cold restart preserves the new values in the database. Performing a download of a module will cause the latest values to now be in the module download script and the Upload values file is no longer needed.
The download flags are shown in the physical network tree, not the Plant Areas.
Not aware of any other download status application.
