Efficient reuse is a goal of many software engineering strate- gies and is useful in the safety-critical domain where formal development is required. Event-B can be used to develop safety-critical systems, but could be improved by a component-based reuse strategy. In previous work, we outlined a component-based reuse methodology for Event-B. The methodology provides a means for bottom-up scalability, and can also be used with the existing top-down approach. We developed a pro- cess for creating library components, composing them, and for specify- ing new properties (involving the composed elements). We introduced Event-B component interfaces and propose to use a diagrammatic repre- sentation of component instances. However, in that approach, the com- munication between components is modelled in an abstract manner. In this paper, we describe a more concrete specification approach which includes interfaces with ‘callable’ interface events. These events model operations, and additional syntactic constructs model their invocation.
