Cicode is a programming language designed for use in Citect SCADA to monitor and control plant equipment. It is a structured language similar to Visual Basic or C.

For more information see Cicode Programming Reference.

You can incorporate .Net objects into a project, allowing you to extend Citect SCADA with components that have been developed externally.

To add .Net objects to your project, see .Net Functions in the Cicode Programming Reference.

You can incorporate ActiveX objects into a project, allowing you to use extend Citect SCADA with components that have been developed externally.

For example, you can:

• Add an ActiveX object to a graphics page (see Add an ActiveX Object)
• Call an ActiveX object using Cicode (see ActiveX Functions in the Cicode Programming Reference.)

Note: ActiveX objects are not supported on a 64-bit process, such as an alarm server operating in Extended Memory mode. If a call to an ActiveX Cicode function occurs from a 64-bit process, an error code will be returned, a hardware alarm will be raised and the Cicode thread will stop.

You can use CitectVBA to extend Citect SCADA. CitectVBA is a Visual Basic for Applications (VBA) and VBScript-compatible Basic scripting language. Citect SCADA has embedded support for CitectVBA.

For more information, see CitectVBA Programming Reference.

Note: CitectVBA is not supported on a 64-bit process, such as an alarm server operating in Extended Memory mode. If a call to a CitectVBA Cicode function occurs from a 64-bit process, an error code will be returned, a hardware alarm will be raised and the Cicode thread will stop.
