You can use SmartPlant P&ID in thin client mode, which supports Citrix.
When you access the SmartPlant P&ID application via Citrix, we strongly recommend that you do not perform any administration activities that run automatically for a long time on a client machine. When you execute administration activities via Citrix client, the software actually performs these activities on the server side, while the client remains idle, and the connection to Citrix is lost, possibly resulting in corruption of data. Examples of these types of administration activities are: upgrading the database to a new version, importing data using Import Manager, or importing reference data using Options Manager. As a workaround, we recommend that you perform these kinds of activities either on your database server machine or on a client machine using a configuration other than Citrix.
When using thin client mode, all users share a common database, resulting in intellectual property being shared between all sites.
In a Citrix environment, links within a .chm file to open a web browser will not work. To view the linked web page, copy and paste the web address into the web browser on your local machine.
