Question
The value of indirect tags ( @<TagName> ) are not shown in the web thin client application.
Answer
When a screen is saved as HTML, Studio saves a
.TAGL file in the WEB subfolder. This file has
the list of all tags configured in the screen (objects and dynamics). When a screen is opened in the Web Thin
Client browser, the tags listed in the .TAGL are “enabled� for TCP/IP communication with the server station. It provides an optimized communication between the server station and the Web Thin Client
stations.
Therefore, when using indirect tags (@), the tags pointed will not exchange data with the Server,
unless they have been configured in the screen. In other words, the tags that will be pointed in the screen MUST
be configured in any object of the screen to enable the TCP/IP communication for these tags with the server
station.
 Tip: Add a transparent rectangle (no fill and no line) in the screen corner. Apply the Command dynamic to this
rectangle and configure the tags (which can be pointed by indirect tags during the runtime in the Web Thin
Client station) in the Expression field (keep the Tag Name field blank). So, these tags will be added to the
.TAGL file and they will be available for TCP/IP communication with the Server station.
