I/O modules may also have associated user parameter data defined by the corresponding GSD
file. The meaning of these parameters (if applicable) is specific to the slave implementation, and
may be altered via the Parameter Assignment tab of the Module Properties form.
Configuration software also provides an additional I/O module to all slaves that is not defined in
the GSD files, which is the Universal Module. The universal module allows the input/output
length, unit, and consistency to be assigned custom values as required – however not all slave
implementations will support this feature (consult the specific slave documentation for details).
The Length parameter defines the length of the input or output module in either bytes or words
(according to the corresponding Unit parameter). The data consistency over the Profibus network
may be applied to the selected unit (i.e. byte or word) or to the total length of the input or output
selection.
Depending on the particular slave, Manufacturer Specific Data may also apply to an I/O module.
This data is a string of hexadecimal bytes, the meanings of which (if applicable) are device
specific and should be detailed in the documentation for the particular device.
Master Properties
The Profibus master WI-
GTWY-9-xxx has some
configurable properties
that affect the entire
Profibus network. These
properties can be accessed
by double clicking the
master icon in the network
busview, or right-clicking
the icon and choosing
properties.
Profibus Tab
The Address parameter
specifies the actual
Profibus address of the
Profibus master (default =
0). Only available
addresses are listed and
can be selected as new
address. The serial baud
rate for the entire Profibus
network is selected – this
is the baud rate that will be used by the master and therefore must also be supported by all slave
devices on the network. Most slaves will support auto baud rate detect, but it should be ensured
that any slave on the network supports the configured baud rate.
The Profile parameter controls the assignment of Bus Parameters for the Profibus network. In
the single master (default) profile, the bus parameters are calculated automatically by
configuration software and are optimized for speed – no other masters may be connected to the
