IWS Interface for PLC Allen-Bradley ControlLogix 5000





This article will describe the interfaces provided by InduSoft Web Studio (IWS) to exchange data with ControlLogix PLCs from Allen-Bradley:
• IWS for RSLogix5000 CSV database : using this tool user can import the tag names and the communication setting from the PLC program. IWS create not only the tags in the application tags database but also the communication driver worksheet automatically. This interface reduces dramatically the time invested to integrate the SCADA/HMI software with the ControlLogix PLC and reduces the configuration errors.
• ABCIP Communication Driver: this driver implements the CIP protocol over Ethernet/IP and exchanges data with the ControlLogix PLC during the runtime, using the tag names configured in the PLC project.

IWS enables you to create or add to Tags database by importing taj=gs froman external application database, including:
• OPC server databases.
• ODBC databases.
• CXV databases.
• PanelBuilder Import Wizard.
• RSLogix 5000 CSV databases (including Allen-Bradley RSLogix CSV files).

When you select File-->Import Wizard, an Import Wizard dialog displays to walk you through the process of importing tags:
importing tags
To begin you must specify the type of database source you are going to use.
• Select RSLogix 5000 CSV from the source type list, and then click the Next button.
• When the next Wizard screen displays, click a radio button in the Option pane to specify of the following options:
import RSLogix 5000
This interface allows the user to import the Tags Database and the communication interface configuration form the ControlLogix/FlexLogix PLC program files.
