VEGACOM 557 Profibus DP 47
Integration of the GSD file
The GSD file of VEGACOM 557 must be
integrated so that the VEGACOM 557 ap-
pears in the instrument catalogue of HW-
Config. The properties of VEGACOM 557
(e.g. possible baud rates) are described in
the GSD file. The GSD file is called
„_COMb208.GSD“ and is included on the
supplied utility diskette, in addition there are
bitmap files for VEGACOM 557. Proceed as
follows to integrate the GSD file:
In the window HW Config you have to choose
under the menu item „Extras“ -> „Install new
GSD...“ the GSD file „_COMb208.GSD“. By
pushing the button „Open“, VEGACOM 557
is integrated in the instrument catalogue. The
bitmaps are installed automatically, if they ar e
in the same the directory as the GSD file.
Plan Master/Host system
As a first step, the complete connected S7
hardware (carrier, power supply unit, CPU,
I/O etc.) must be planned. After a CPU or a
communication processor with DP interface
has been added, a Profibus network must be
created now. Under „Properties“ -> button
„PROFIBUS“ of the DP master , a new Pr ofi-
bus network will be created with the button
„New“.
Create new Profibus network
Setup
After a Profibus network has been created,
the baud rate and the bus parameters for the
Profibus network can be chosen via the but-
ton „Properties“ and „Network adjustments “.
Plan Profibus-Slave VEGACOM 557
In the instrument catalogue of the window
HW Config you must choose under „Profibus
DP“ -> „Additional field devices “ -> „GATE-
WAY“ VEGACOM 557. With Drag & Dr op
VEGACOM 557 can be now allocated to a
Profibus network. The following steps have to
be carried out:
I. Selection of the operating mode:
As soon as VEGACOM 557 has been allo-
cated, the enquiry for the operating mode
is made. In this window „Selection of the
desired configuration“ the r equested oper-
ating mode must be selected.
II. Allocate Slave address:
After selection of the operating mode, the
enquiry for the Slave address and the
Profibus adjustments (baud rate etc.) is
made in an additional window.
The planned Slave address must correspond
to the Slave address that was set with the
DIL-switch on VEGACOM 557.
III. Allocation of input and output addresses
for VEGACOM 557
In the window „Properties - DP-Slave “ the
input and output addresses for VEGACOM
557 can be allocated. The window can be
reached by marking VEGACOM 557 (click-
ing the ICON of VEGACOM 557) and dou-
ble clicking in the chart of VEGACOM 557
in the line with „Universalmodul“. In the
window that opens, the initial address of
the input or output section can be deter -
mined. The „Length“, „Unit“ and „Consist-
ent over“ must not be modified. The
number of bytes reserved by VEGACOM
557 in the address space of S7, depends
on the selected operating mode.
