1. A method for operation of a process automation system in which at least two protocols P1, P2 are utilized, the process automation system including at least one P1-aware component and at least one other component using P2, the at least one other component using P2 being unaware of P1, the method comprising:

  • detecting, in the at least one P1-aware component, an occurrence of a volume data transfer from the P1-unaware component;

    requesting, by the P1-aware component upon detecting the occurrence of the volume data transfer, for bandwidth on behalf of that P1-unaware component to decrease the communication time and subsequently releasing the requested bandwidth;

    implementing download detection inside of a P1/P2 Linking Device or Proxy; and

    at least one of requesting and releasing bandwidth through a P1 resource management function using corresponding commands standardized within P1,wherein an upload/download is detected by one of;

    explicit initiation of the up/download in the P1-aware component,automatic detection in the P1-aware component, and wherein bandwidth is requested and released by at least one ofusing proprietary mechanisms of a P1 communication master or its integration components including at least one of an FDT Communication Device-Type Manager (DTM), Field Device Integration (FDI) Gateway Device Package, and a FDI Communication Server,implementing a proprietary command in a P1/P2 linking device or field device that causes them to request bandwidth from the P1 communication master or their integration components, andsending a corresponding standardized request command directly to a P1 resource management function.
