There is two way to configure trend from Engineering station or from CBF via (i) Trend Function Block or (ii) Free Trend display, also you can configure user defined trend from DigiVis operator station
(i)Trend Function block : Using trend function block it is easy to connect pin of any block to trend FB, just you need to draw lines.
(ii)Free Trend display: You need OPCS and Trend gateway to be configured, go to CBF project tree > DigiVis > TR_D-OS (double click) > Select ‘user variable acquisition’ > press F2 in variable field and you can find last tab ‘Select a tag component’. For free trends check your resource/trendgateway/OPCS is downloaded with latest changes.
(iii) From user defined trend you can only select variables from variable list.
In your case you can use option(i) &(ii), Hope it helps to you...
