Information Layer (RAMI 4.0)
General desciption of Information Layer (RAMI 4.0):
The information layer focuses on standards that regulate information flows, information objects and data models being used by components, services and their functions to exchange information. A common semantic base is the key requirement to ensure consistent integration of different data and achieve interoperability between components at this layer.
B2MML – Business to Manufacturing Mark-up Language. Data standard used to define the process (i.e. the set of operations to be carried out by the cell for each unique product), what resources are required for each process, the materials needed and more. The full process would be designed by engineers, and then the SCADA would break the ‘master’ B2MML process representation into sub-processes and send these to the resources via the service bus. These would then trigger the start of processes by the PLCs.
