This chapter provides information about the supported functions for Allen-Bradley devices, and how to access these functions.

3.1 Accessing DAS Functions

DAS for AB INTERCHANGE software functions are accessed through the following BASEstar Classic device connection management interfaces:

• Command line interface (CLI)
• Menu interface
• Application programming interface (API)

Command Line Interface (CLI)

To access the BASEstar Classic device connection management CLI, enter the following command at the DCL prompt ($):

$ BSTAR DCM

For information about BASEstar Classic device connection management commands, refer to the BASEstar Classic Command Line Interface User's Guide.

Menu Interface

To access the BASEstar Classic device connection management menu interface, enter the following command:

$ BSTAR/MENU

For additional information about the BASEstar Classic device connection management menu interface, refer to the BASEstar Classic Menu Interface User's Guide.

Application Programming Interface (API)

Not all device connection management functions are available through every interface. When a function is limited to a particular interface, it is described specifically in the description of the function. If a limitation is not specified, the function is available through all device connection management interfaces.
