Abstract: The disclosure herein provides an automated fiber placement assembly for forming a component, such as for a turbine engine or non-turbine engine system, by the placement of separate layers or strips of fiber tows. The automated fiber placement assembly comprises a heated pressure roller to heat the strip of fiber tows as they are placed during formation of the component. The pressure roller can be heated to heat the strip of fiber tows, or an alternate roller, separate from the pressure roller, can be heated to heat the strip of fiber tows.

Abstract: An industrial integrated development environment (IDE) system includes device definition creation tools that can be used to select, configure, and add multiple device definitions to a control project using a single workflow. A device selection interface can be used to select multiple device definitions to be added to the project, and a device configuration interface can be used to set values of each device's configuration parameters. Upon completion of this device selection and configuration workflow, all selected device definitions and their associated configuration parameter values are added to the control project substantially simultaneously. The workflow allows the user to initially identify a parent device, backplane, or network to which the new devices will be assigned, or to add the new devices as unassigned devices and assign the new devices to a selected parent device, backplane, or network after creation.
