No trend data in DigiVis
Using Freelance 8.1 and 8.1 SP1 with an engineering staion, 1 DigiVis with Trendserver, 1 DigiVis with OPC Server. Adding an new Panel with just DigiVis, setting DCOM as described with the result of no trend data in all configured trends (trends are configured using trend server). On existing machines trend display is ok.
Is there a problem with DCOM, security or even time sync?
Thanks very much in forward!

First could be DCOM, windows login name should be same and lots of other settings there strictly follow the precedures as mentioned in manual.
Second problem could be of time synch, if so
Exit DigiVis and check that in configure window time synch is enabled ? if not enable and start digivis again.
If both the things are fine, third check trend gateway is downloaded ? means not showing arrow mark ! if it is not downloaded then download and then download digivis again.
Also check newly added digivis is connected to controllers from where digivis is getting data. double click on conf in project tree you will get configure window there you can find this mapping.
good luck !
