Overview

Use

Library Designer

to assign the project, the controller, and any of the Logix objects to one or many library objects. Each library object defines a set of functions, capabilities, and connections. For example, those that support the functions of the valve, motor, and controller modules. Rather than being tied to one application, library objects can be configured to meet the needs of multiple applications.

Library Designer

allows the publishing of a library directly into an ACM database. Options include the ability to specify the location where the library will be published in the ACM database, and the ability to specify the status of the library, either Published or Pending.

Custom properties called "Decorations" can be added to a library object using

Library Designer

. Decorations include parameters, subobjects, functions, substitutions, and external references. Decoration lets the library object be configured when it is implemented in a project in

Studio 5000® Application Code Manager™

.

Logix objects can be restricted to a single library object or assigned to multiple library objects, each with a different set of decorations. A library object can contain a single Logix object, or a Logix object can be added as an element of a more complex library object. For example, a P_Alarm Add-On Instruction can be assigned to a valve library object and can also be an element of a Motor or Pump library object.

Each ACD file can support multiple projects, controller libraries, and library objects. The ACD is not required to contain a project or controller library. While the decoration is stored as part of the ACD file, it is treated as a separate layer of information from the base controller code and does not affect code execution.

Decoration controls how the library object is instantiated, including configurations such as naming, tag values, conditional inclusion, and connections to other library objects. One or many distinct instances of a library object can be instantiated within an ACM project and each instance can be separately configured. By using

Library Designer

, each Logix object can be published directly to the ACM database or to a file in HSL4 format.

The

Library Designer

performs these tasks:

Validation is an important part of any code-based system and the

Library Designer

and

Application Code Manager

tools can validate objects within a library structure and controller projects respectively to ensure an error free library or ACM project. The configurable fields within the

Library Designer

or

Application Code Manager

display a validation error or warning icon when an invalid value is specified. For example, If an invalid character is included in a parameter name. The field would be highlighted with an error icon. Hovering over the error icon for error resolution information.
