Viewing 1734-AENT PointIO Adapter I/O Addresses

Overview

Because the Device Library includes EDS files for the 1734-AENT PointIO adapter and its discrete input and output modules, the Control Expert EtherNet/IP configuration tool automatically:

creates a rack optimized CIP connection from the TSX ETC 100 EtherNet/IP communication module to the 1734-AENT, and
configures each input and output item by assigning:
- an item name
- an address location
- a size allotment based on its data type

NOTE: In this example, the configuration tool created a rack optimized connection, which is more efficient. A rack optimized connection can be used only with discrete (digital) I/O modules. For analog I/O modules, each analog module must be connected to the ETC 100 using a separate connection.

Viewing the CIP Connection and I/O

To view the automatically created CIP connection and the I/O items in the Control Expert EtherNet/IP configuration tool:

Step	Action
1	In the Devices window, select the 1734-AENT:
2	In the Protocol menu, select Properties. The Properties window opens for the remote device.
3	In the Connections tab, under the topmost Rack Optimization connection, select General. The rack optimized connection properties are displayed in the Connection Parameters list:
4	In the Devices window, navigate to and select the first Rack Optimized connection item at Position 000, as shown below: The automatically configured input and output items appear on the right side of the screen in the I/O area (as depicted in the next step, below).
5	If necessary, use the horizontal scroll bar to scroll to the far right of the input or output area and display the Address column, which identifies the location of the input or output in the TSX ETC 100:
