  The European Spallation Source (ESS) in Lund, Sweden has just entered into neutron beam line construction starting detailed design in 2015. As a collaboration of 17 European countries the majority of hardware devices will be provided in-kind. This presents numerous technical and organizational challenges for the construction and the integration of the neutron instrumentation into the facility wide infrastructure; notably the EPICS control network and the facilities absolute timing system. In this contribution we present a strategy for the modularity of the instruments hardware with well-defined standardized functionality and a minimized number of control & data interfaces. Key point of the strategy is the time stamping of all readings from the instruments control electronics extending the event mode data acquisition from detected neutron events to all metadata. This gives the control software the flexibility necessary to adapt the functionality of the instruments to the demands of each single experimental run. Examples of the advantages of that approach in classical motion control as well as in complex robotics systems and matching hardware requirements necessary, is discussed.
