PROCESS CONTROL ASSEMBLY FOR A PROCESS AND/OR AUTOMATION TECHNOLOGY APPARATUS

摘要

The invention relates to a process control assembly (PKA) for a process and/or automation technology apparatus having a plurality of and in particular varying field bus systems (DP1, PA1, FH) and having a plurality of field bus interfaces (PAP1, PAP2, PAP3), wherein each of the field bus systems (DP1, PA1, FH) is connected to at least one of the field bus interfaces (PAP1, PAP2, PAP3). The field bus interfaces (PAP1, PAP2, PAP3) serve for communication between the field bus systems (DP1, PA1, FH) and a communication level (ET2) superior to the field bus systems, such that only a first of the field bus interfaces (PAP1) is directly connected to the superior communication level (ET2) and the field bus interfaces (PAP1, PAP2, PAP3) are connected in series to one another starting at the first of the field bus interfaces (PAP1).
