General section 1. General specifications
This section contains the vendor name, the device name, hardware- and software
release versions, station type and identification number, protocol specification
and supported baud rates.
DP-master section 2. DP master-related specifications
This section contains all parameters which only apply to DP master devices
(e.g. maximum memory size for the master parameter set, maximum number
of entries in the list of active stations, or the maximum number of slaves the
master can handle).
DP-slave section 3. DP slave-related specifications
This section contains all specification related to slaves (e.g. minimum time
between two slave poll cycles, specification of the inputs and outputs, and
consistency of the I/O data).
Configurator The device data base file of each device is loaded in the configurator and
downloaded to the master device. Refer to the Operation Manual of the
PROFIBUS-DP Master Unit for usage of the GSD file in the master’s
configuration software.
GSD files are usually supplied with each unit. Alternatively, GSD files can be
downloaded from the Internet, either from the manufacturer’s site, or from the
GSD library of the PROFIBUS Nutzerorganisation at http://www.profibus.com.
3.1.5 Profiles
Exchanging devices To enable the exchange of devices from different vendors, the user data has
to have the same format. The PROFIBUS-DP protocol does not define the
format of user data, it is only responsible for the transmission of this data. The
format of user data may be defined in so called profiles. Profiles can reduce
engineering costs since the meaning of application-related parameters is
specified precisely. Profiles have been defined for specific areas like drive
technology, encoders, and for sensors / actuators.
3.2 Introduction To GWY-500
GWY-500 is a communication bridge between Profibus Network interface on one side and various serial protocols on the
other side. GWY-500 allows serial devices to act as Profibus Slave on Profibus Network.
