GW-7553 PROFIBUS/Modbus TCP Gateway
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 GW-
7553 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.

Description
When the GW-7553 is a Modbus Slave device and receiving query message form Modbus Master device, PWR led will flash.
Power supply is ok.
The firmware has loaded.
Power supply has failed.
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).

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.
4. Software configuration
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.
File -> CopyGSD
(Directory: --> CD:\profibus\gateway\gw-7553\gsd\)
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.
GW-7553 PROFIBUS/Modbus TCP Gateway Quick Start (Version 1.10, May/2012) PAGE ： 3
Step 1: Click insert slave button in the PROFIBUS configuration tool.
Step 2: Choose GW-7553 device and click Add button.
Step 3: Set address of GW-7553 and then click OK button.
Step 4: Finish adding GW-7553 in the DP-master
Set the parameters of the GW-7553
The user needs to change “Modbus Type” to Slave, “Modbus Format” to
Modbus TCP and use the default value in the other parameters in this example. Please refer to user manual section 4.3 The Configuration of the common parameters.
Double click the GW-
7553’s icon to enter the
Slave configuration dialog
Click <Parameter Data> button to enter the Parameter Data dialog
GW-7553 PROFIBUS/Modbus TCP Gateway Quick Start (Version 1.10, May/2012) PAGE ： 4
Change “Modbus Type” to Slave, “Modbus
Format” to Modbus TCP and click <OK> button
Set the modules of the GW-7553
The modules of the GW-7553 are described below.
●
System setting module ： 3 byte out
●
Output module ： Output Relay/Coil 1~32 Bytes
Output Register 1~64 Words
●
Input module ： Input Relay/Coil 1~32 Bytes
Input Register 1~64 Words
In this example, we configure a “System Setting” module, an “Output
Relay/Coil--2 Byte” module and an “Input Relay/Coil--2 Byte” module, as follows.
Double click GW-7553’s icon to enter Slave configuration dialog
Configure module and click OK button
When the user finishes the configuration and saves setting in the PROFIBUS
Master station successfully, the 'RUN' LED indicator of GW-7553 is turned on.
That shows the GW-7553 working in the data exchange mode.

5. GW-7553 module communication test
This demo uses utility “MBTCP” on the PC to communicate with the GW-
7553. The User can download it on the web site: http://ftp.icpdas.com.tw/pub/cd/8000cd/napdos/modbus/modbus_utility/ . The settings of the “MBTCP” are shown in the below.
Input GW-7553’s IP (ex: 192.168.0.107) and click “Connect” button
PROFIBUS input test
--Send command to write DO of the GW-7553
The user needs to input command (” 01 0F 00 00 00 10 02 FF FF”) here and click <Send Command> button to send Modbus command and then MBTCP can receive response message (” 01 0F 00 00 00 10”). The user can find byte
0, 1 of input data area of PROFIBUS Master device have changed into
“0xFF” at this time, as shown in the below.

PROFIBUS output test
--Send Command to read DI of the GW-7553
The user needs to input command (” 01 02 00 00 00 10”) in MBTCP and click <Send Command> button to send Modbus command and then MBTCP can receive response message (” 01 02 02 00 00”). In this message, the user can know the value of DI0 & DI1 is “0” in the GW-7553.
--Send output data to write DI of the GW-7553 by the PROFIBUS Master
The user needs to set “0xFE” & “0xDC” in byte 3 & byte 4 of output data area of PROFIBUS Master device and then set the value of the first byte from
0 to 1 to trigger the data output command.
--Send command to read DI of the GW-7553 again
Now the user can input command (” 01 02 00 00 00 10”) in MBTCP and click <Send Command> button to send Modbus command again. Then
MBTCP can receive response message (” 01 02 02 FE DC”). In this message, the user can know the value of DI0 & DI1 have changed into “0xFE” &
“0xDC” in the GW-7553, as shown in the below.
