There are multiple categories of wire harness manufacturing machines, each with different capabilities. Yet many of them have a local data store to keep part, spec and article information. This means that there are multiple ways to send part, article and job information to a machine.
Job Management is based on ISA95 and Machinery Job Control. This section provides some examples for use in a wire harness. These examples illustrate the concept with consideration of domain-specific aspects, such as different ways to transfer data.
Other workflows, or a mix of these examples is also possible. This example also represents a simplified version of the model.
In general, it is important that all information needed for the process is available beforehand. This means that a job can only be stored if the article spec is available (or sent with the job). Likewise, the article spec can only be stored if the part information is already available (or sent with the article spec). Thus, the model does not further restrict the base specifications. Some aspects are not shown in this example.
Parts of the original model are omitted for illustrative purposes.
