| Flexibility,maintainabilityandevolvabilityareverydesirablepropertiesformodernautomationcontrolsystems. In order to achieve these characteristics, modularity is regarded as an important concept in several scienti fi c domains. The reuse of modules facilitates the reproduction of functionality, or extensions of existing systems in similar environments. However, it is often necessary to prepare such an environment to be able to reuse the intended programmed functionality. In an IEC 61131-3 environment, cross-vendor reuse of modules is problematic due to dependencies in proprietary programming environments and existing con fi gurations. In this paper, we aim to enable cross-vendor reuse of modules by controlling these dependencies. Our approach is based on the Normalized Systems Theory, from which we derived three guidelines for the design of reusable modules in an IEC 61131-3 environment for automation control projects. These guidelines are intended to support programmers in controlling dependencies, regardless of the commercial programming environment they work with. |
