Initially work concentrated on editing the specification document for UESP. Here component classes have been defined for all available power supply components and loads. General systems layout of UESP systems have been designed, considering the specific requirements of the various target applications (from small telecom power supply
to minigrids). For the communication bus CAN (Controller Area Network) has been chosen. It is widely used in the automotive industry and therefore is both reliable and inexpensive. The basic communication procedures between components as well as their parameter sets and quantities have been specified.

Currently the UESP component interfaces are developed. They will enable for conventional components to be operated in a UESP system as long as UESP compatible components are not commercially available. Simultaneously the first version of the software protocol stack is developed. Shortly system tests will be carried out.
