Quick Start User Guide
1. Introduction
This manual introduces the GW-7553's basic setting and operating quickly, the user
can refer to the user manual in the ICP DAS companion CD-ROM (Path:
“CD:\profibus\gateway\gw-7553\manual\gw-7553 user manual.pdf”).
This manual helps users to understand about the GW-7553 module and application.
In the following examples the CIF50-PB PROFIBUS Master card from Hilscher is
used. The configuration and communication is done by the program “SyCon”
provided by Hilscher.
Application example of PROFIBUS to Modbus TCP
In this example the GW-7553 acts as a Modbus TCP Slave device. When the GW7553 module receives a write DO Modbus command from PC’s Ethernet Port, the
GW-7553 module can send the message to the input data area of PROFIBUS Master
station. When the GW-7553 module receives a read DI Modbus command from
PC’s Ethernet Port, GW-7553 module can refer to the output data area of
PROFIBUS Master station to produce response message and send it to PC’s
Ethernet Port.

PROFIBUS connection
Here we recommend users to use the standard PROFIBUS cable and
connector (DB9 male). It is only needed to use D-type connector via
PROFIBUS cable to connect PROFIBUS Master station and GW-7553
module. PROFIBUS Master station and GW-7553 module belong to terminal
equipments in this example, thus we need to enable the terminator resistor in
the D-type connector.
Address setting
The GW-7553 is a slave device of PROFIBUS DP protocol. The station address
of GW-7553 can be set by DIP switch. The DIP switch can be seen by open the
cover, as shown in the below. The range of DIP switch is 0~126, here we set
GW-7553 module’s DIP switch to 1.

flash
When the GW-7553 is a Modbus Slave device and receiving
query message form Modbus Master device, PWR led will flash.

flash
When the GW-7553 connects with the utility tool, it will flash
fast (flash once about 55ms).
When the GW-7553 has diagnostic message, it will flash slowly
(flash once about 220ms).

Data exchange mode.
It is normal operation.
RUN
off GW-7553 module is not in data exchange mode.
3. Establish connection with GW-7553
Before establish the connection between DP-Master and GW-7553, users
should obey the following steps first.
1. First, users must load the
electronic device description file
(GSD file) of the GW-7553 into
the DP-Master.
2. And then set the parameters and
configurations.
3. Finally change your DP-master
from offline state to operate
state. The GW-7553 will be
initialized. If there is no error
occurs, GW-7553 proceeds into
data exchange state. At the
meantime, if there is any error
occurs, GW-7553 will return to
wait for parameterization.

GSD file
Please copy the GSD file (IPDS0C0D.gsd) and the bitmap file (ICP_7553.
bmp, GW_7553.bmp) from the CD of the GW-7553 module into the Profibus
configuration tool.

the example of how to load GSD file
Here, we use the hilscher CIF50-PB PROFIBUS communication interface to
show how to load GW-7553’s GSD file step by step.
