PROFIBUS PA means 'PROFIBUS for Process Automation'
PROFIBUS PA is the solution from PROFIBUS, the world's most popular fieldbus, for the process industry. PROFIBUS PA comprises all technologies and functionalities that enable the successful use of advanced fieldbus technology in process automation.
With its 'PA Solution', PROFIBUS is definitely better equipped than any other fieldbus to meet the demanding requirements of the process industry with its very specific production environments where typically discrete and continuous processes are closely linked together in one plant.
From chemicals and pharmaceuticals, food and beverage to oil and gas, cement and metals, water and wastewater, PROFIBUS PA is proving its worth on a daily basis in all sectors of process industries. With its system-wide uniform communication, the application-specific device profile and the extensive and very flexible diagnosis concept, ROFIBUS PA provides a consistent response to all tasks within a plant, from inbound logistics through process automation to outbound logistics.
The qualities of PROFIBUS PA provide the user with an enormous potential for cutting costs over the entire life cycle of a plant, from planning, engineering and commissioning to operation and maintenance.
And all this combined with evidently very easy handling.
PROFIBUS automates all tasks in a process control system with a single integrated bus.
In more complex process devices, application profiles ensure the unification of typical device functionalities, e.g., „PA Devices” for process devices „PROFIdrive” for drives „Ident” for barcode readers, etc. Communication between all PROFIBUS devices takes place uniformly via the PROFIBUS DP communication protocol.
All devices equipped with a PROFIBUS interface can be used, while several transmission technologies are available for selection. Of these, the following are preferred:
