That is not how display services works ...
Display services client works only with IM. You must build dedicated IM displays. It does not open the workstation Process Graphics
Smart Client works with a Smart client server. It does not need an IM (Except for alarm history ). Smart Client can open converted 800xA workstation PG2 graphics
With Display Services you can build simple graphics with live data from 800xA. Its not capable of viewing PG2 nor VB6, only its own type of displays.
Check the Display Services server's health, eg with the Server Status tool. Server running? Check Windows Event Log for events from "ADS".
Display service:You can connect your custom-built displays to a variety of data sources. For example, you can use Display Services to build and run a display for viewing trend data collected by Information Manager History Services. You may also connect the same display to a third-party database, for instance an Oracle database on a remote Information Manager node
The Display Client: provides the graphical user interface for display building and
viewing, and for administration of Display Services.Here Infomration management server is mandatory to run the display clients.
Please refer the attached manual.
Smart Client:Retrieves the data from control system through the smartclient data provider.Here you need dedicated smartclient server(web server) which manges all users,smartlcient applications in it
Here Information management server is optional (you select only when infromation management history & events required )else you can run the data provider in connectivity server itself (to provides only real time data & basic history )
Please refer the attached doc.
