VBScript Reference Manual for InduSoft Web Studio

InduSoft Web Studio VBScript Reference Manual
Command Dynamic
A Command Dynamic is associated with a specific object on a Screen, and allows one or more actions
to take place when an event occurs with the specific object. A typical use is a button (perhaps a
rectangle) that is placed on the screen. When an operator selects on the button (via mouse click or
pressing a touch screen over the object), this action is expected to initiate some action. That action may
be to set/reset a PLC bit, jump to a different screen, whatever. The Command Dynamic allows the
developer to choose what action to take.
With Version 6.1, IWS adds new capability to the Command Dynamic interface. In addition to the IWS
built-in language command, the Command Dynamic can now execute VBScript code. The steps to
access the VBScript interface within a Command Dynamic are:
1. Select the object on the Screen currently opened in the IWS workspace. If the object has
a Command Dynamic associated with it, then right click on the object. Otherwise, click on
the Command Dynamic icon (right) from the Mode toolbar and then right click on the
object.
2. Now, the Object Properties dialog box for the
Command Dynamic will open. Click on the Config…
button in the lower right corner of the dialog box.
3. Select the event condition (e.g. On Down) where
your want code to be execute and then select
VBScript as the Type.
4. Enter your VBScript code (variable declarations
and executable statements).
Within the Command Dynamic, you enter VBScript
variables and executable statements subject to the
following conditions:
• Any variable declared in this interface will only
have a local scope.
• You cannot implement procedures (i.e.
Subroutines or Functions) within this interface.
Notwithstanding these restrictions, VBScript code within
a Command Dynamic still has access to all Global
Procedures.
VBScript code within the Command Dynamic interface is
executed whenever one or more of the selected event
conditions (listed in the Command Dynamic configuration screen) occur for the selected object. The
execution of the Command Object script on the Server executes independently from the execution on
Web Thin Clients.
Key Notes:
• Before executing the application, be sure to save (or close) the Screen after any
VBScript is entered. Otherwise it might not be updated. This is true for all VBScript
interfaces.
