PROFIBUS DP/PA

PROFIBUS DP/PA is the leading fieldbus on the market. All Siemens gas analyzers with an
optional – also retrofittable – plug-in card are Profibus-compatible and comply with the
binding "Device profile for analyzers" defined by the PNO (PROFIBUS International). Central
access to the system analyzers is possible with the SIMATIC PDM software tool.
"Fieldbus" is the name of a digital communication system with which distributed field devices
of a system are linked to each other over a single cable and are simultaneously connected to
programmable controllers or a process control system.
