1. SCOPE
This document specifies the features of IEC 61499-1
and 61499-2, according to the guidelines given in
IEC 61499-4, to be implemented in order to
demonstrate:
- interoperability of devices from multiple
suppliers;
- portability of software between software tools of
multiple suppliers;
- configurability of devices from multiple vendors by
software tools of multiple suppliers; and
- interchangeability of devices and resources from
multiple vendors.
The features to be demonstrated are illustrated in Figure 1.
NOTE - The sensor/actuator links designated #1 and #2 in Figure 1.1 may be non-interoperable. However, it is
intended that feasibility demonstrations conforming to this Agreement
may show the transfer of events and data from sensors on one link to
actuators on another link using appropriately configured and
interconnected service interface function blocks.
