Page 32: Profibus Pa
Description 3.6 PROFIBUS PA PROFIBUS PA 3.6.1 Overview The Process Field Bus (PROFIBUS) is an open communication system for automation technology and is specified in the European standard EN 50170. PROFIBUS Process Automation (PROFIBUS PA) is a variant of PROFIBUS Decentral Peripherals (PROFIBUS DP), which is widely used in process technology.
Page 33: Properties
Description 3.6 PROFIBUS PA Class-1 master Class-2 master (Klasse 1) PROFIBUS DP PROFIBUS PA Field devices, decentralized periphery, subordinate Controls, gateway to PROFIBUS PA Figure 3-15 Functional principle of the PROFIBUS automation system The figure shows a section of a typical PROFIBUS automation system. The control system consists of two masters with distributed tasks.
Page 34: Connection
Description 3.6 PROFIBUS PA necessary basic information to find profile parameters. One parameterization tool serves all profile-conforming devices, regardless of type or manufacturer. Depending on the size of the installation (and therefore the number of field devices) and the time behavior required, you implement the system with one or more PROFIBUS PA strands. One PROFIBUS PA strand consists of the components shown in the following figure.
Page 35: Number Of Connectable Devices
Description 3.6 PROFIBUS PA For reasons related to transmission technology, the bus is also equipped on the far end with a terminating resistance T. When using the recommended bus cable, the theoretical maximum cable length is 1900 meters. The theoretical maximum cable length is the sum of all cable segments.
Page 36: Assigning The Device Addresses
The next positioner is then connected to the bus and processed the same way. We recommend writing the set address on the field device with a wipe resistant pen.

Page 277: Glossary
Glossary Analog A signal type which represents data using continuously varying, measurable and physical quantities, e.g. current or voltage. Opposite to digital. The range between 4 and 20 mA is often used to transfer analog signals. Analog-to-digital converter An analog-to-digital converter is an interface between the analog environment and the digitally working computers.
Page 278 Glossary Configuration See parameterization. Cornerstone Management software for process instrumentation. Dangerous failure Failure with the potential to switch a safety-instrumented system to a hazardous or non- functioning safety status. Dangerous failure Failure with the potential to bring the safety-instrumented system into a dangerous or non- functional status.
Page 279 Glossary Device category 3 Category 3 devices must be procured such that they ensure a normal degree of safety. Devices in this category must ensure the required degree of safety in case of frequent faults or the ones that are normally expected, e.g. defects in the device, and prevent the ignition sources.
Page 280 Glossary Fieldbus A fieldbus is an industrial communication system used to connect a number of field devices with a control device. Field devices include measuring sensors, final controlling elements and actuators. Final controlling element Converter that converts electric signals into mechanical or other non-electric variables. Firmware Firmware (FW) is the software embedded in a chip in electronic devices.
Page 281 Glossary bus. HART implements the widely used 4/20 mA standard to transfer analog sensor signals. Existing cables of the old system can be used directly and both systems can be operated simultaneously. HART specifies several protocol levels in the OSI model. HART enables transfer of process and diagnostics information and control signals between field devices and superordinated control system.
Page 282 Mixture of air, combustible gases, vapors or mist. Process device manager PDM is a Siemens software package for project planning, parameterization, commissioning and maintenance of network configuration and field devices. Part of SIMATIC Step7. Used for the configuration and diagnostics of SIPART PS2.
Page 283 Glossary Protocols Protocols contain information about data formats, time sequences and error handling when exchanging data between computers. A protocol is a convention about establishing, monitoring and terminating a connection. Different protocols are required for a data connection. Protocols can be assigned to every layer of the reference model.
Page 284 Glossary The international standard IEC 61508 defines four discrete safety integrity levels (SIL) from SIL 1 to SIL 4. Every level indicates a probability range for the failure of the safety function. The higher the SIL of the safety-instrumented system, the higher the probability that the required safety function works.
Page 285 Glossary Zone 22 Zone 22 is an area in which a potentially explosive gaseous atmosphere in the form of a cloud of combustible dust in air never develops or develops only for a short while during normal operation.
