Automation device and method for accelerated processing of selected process data

摘要

Automation device (6) with at least one fieldbus interface (12) for connection to a fieldbus (2) and transmission of data packets (DP) with process data (PD) via the fieldbus (2) and with at least one local bus interface (21) for connection to a local one Bus (7) and transmission of process data (PD) between field devices (9a, 9b, 9c) connected to the local bus (7) and the automation device (6), and with means for converting the data packets (DP) coming from the fieldbus (2) ) in a data stream (DS) for the local bus (7) and for converting the data stream (DS) directed from the local bus (7) to the automation device (6) into data packets (DP) for the fieldbus (2), the automation device (6) has an acceleration unit (10) for the selection of accelerated process data (PDS) and for the separate implementation of the selected process data (PDS), which is set up in such a way that the selected process data (PDS) occurs before in conjunction with the sel output process data (PDS) with transmitted, unselected process data (PDN) are output ...
