FDT-based device parameterization
PROFIBUS PA and PROFIBUS DP devices come along with GSD files for use in PROFIBUS engineering
systems. PROFINET devices are delivered with GSDML files instead of GSD files. Therefore the PA devices
GSDs have to be converted into a GSDML format. Compared with engineering PA devices in PROFIBUS
Masters, our conversion tool is the only additional tool that needs to be used to engineer PA devices in a
PROFINET Controller environment when using the pnGate PA.
1.2 Intended use
pnGate PA is a gateway between PROFINET and PROFIBUS PA devices.
CAUTION
The unit must not be used in explosion hazard areas. The permissible ambient conditions given

3Introduction to PROFIBUS PA
PROFIBUS (PROcess FIeld BUS) is a world leading fieldbus communication standard in automation
technology. It is designed for digital data exchange within a network using a single bus cable and achieves a
high data transmission reliability. Based on different related application profiles, it provides solutions for a
wide range of application areas including manufacturing and process automation (see figure below).
The capabilities of individual PROFIBUS field devices are described by the General Station Description (GSD)
files, supplemented by the Electronic Device Description (EDD) files. The GSD file contains the key data of
an individual PROFIBUS slave, information about its communication capabilities and, e.g. diagnostic values.
It supplies all information necessary for the cyclic exchange of measured values and calculated variables
between the field device and the PROFIBUS master, and supports the configuration of the PROFIBUS
network. The EDD file provides additional information describing application-specific functions and the
parameters of complex field devices. It comprises a description of acyclically communicated device
capabilities, including graphics-based options, and device information such as order data, materials,
maintenance instructions, etc.
In 1996, the first PROFIBUS Process Automation (PA) application profile was released (current version is
3.02, released in April 2009). It uses the PROFIBUS DP communication technology and especially addresses
process automation needs. PROFIBUS PA is suitable for use in hazardous and potentially explosive areas
(Ex zones 0 and 1). In addition to supporting the standard PROFIBUS DP transmission technology RS485,
PROFIBUS PA can also perform the data transfer based on Manchester Coded Bus Powered (MBP), which is
capable of supplying power to the individual field devices via the bus wire.
As a consequence, the wiring overhead can be reduced significantly. MBP communication requires only
8Bits for encoding a character. Thus, PROFIBUS PA meets the requirements for a much simpler and safer
installation and boasts all the benefits of digital transmission right down to the field device. PROFIBUS PA
also supports intrinsically safe applications providing explosion protection by limiting the power supplied
by the bus or the installation components in the field. It is widely used in chemical, oil, and gas industry
applications. The MBP transmission technology basically supports a variety of different topologies,
including linear and simple tree structures. In practice, the „Trunk & Spur Topology“ (see figure below) has
established itself as the de-facto standard, as it is particularly clear and well laid out. Thanks to the
technically mature installation technologies available on the market, it also exhibits a high degree of
robustness. The overall length of a segment may not exceed 1,900m, and the length of the spurs in
intrinsically safe applications is limited to 30m and must be taken into account when calculating the overall
length.

Chapter 3 - Introduction to PROFIBUS PA
Copyright 2016 Softing Industrial Automation GmbH 11
Trunk & Spur Technology Used by PROFIBUS PA and Coupling of PROFIBUS PA Segments to PROFIBUS DP
PROFIBUS PA is based on the PROFIBUS DP-V1 version. It uses the PROFIBUS DP protocol at a data
transfer rate of 31.25Kbit/s and is connected to a PROFIBUS DP network using a coupling device.
PROFIBUS DP then acts as a backbone network for transmitting process signals to the controller.
The PROFIBUS PA application profile defines functions and parameters for process control devices, such as
transmitters, actuators, valves, and analyzers. These functions and parameters are used to adapt the
devices to the respective application and process conditions. The functions are based on Function Blocks,
and the associated parameters are classified as input, output, and internal parameters. The PROFIBUS PA
application profile also determines how the various services of the PROFIBUS communication protocol are
used. This means, for example, that process data that is exchanged cyclically is based on a standard format
for all devices. In addition to the measured value and/or manipulated measurement value, this format also
features a status supplying information about the quality of the value and possible limit violations. It
thereby provides the foundation for harmonized applications, simplified engineering, device
exchangeability and increased reliability by means of standardized diagnostic information.
The latest version V3.02 of the PROFIBUS PA application profile especially addresses user requests for
comprehensive diagnostic and status information as well as the requirements of system-oriented asset
management for field devices within process automation applications.

4.1 Install hardware
Note
If ambient temperatures exceed 55 °C at the place of installation, it may occur that the
temperatures of connecting cables strongly rise if those cables have been put in place in an
unfavorable condition. In such cases, either perform measurements to confirm that the
service temperature of the cables is not exceeded (i.e. 80 °C), or use such variants that
withstand temperatures of minimum 90 °C.
4.1.1 Mounting and dismounting
