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.

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.

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.

on off RUN on off The connection is error with PROFIBUS Master device or PROFIBUS system configuration is not correct. PROFIBUS system configuration is correct. It is normal operation. Data exchange mode. It is normal operation. 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.

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 ¾ 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.

Click Download> to download the setting into PROFIBUS Master station ¾ Set the network configuration of the GW-7553 Set the network configuration of the GW-7553 by Profibus/Modbus gateway utility (please refer to user manual section 5.5 & 5.6 for detail). The user can download the utility from the CD of the GW-7553 (path: “CD:\profibus\ gateway\gw-7553\utilities\”). The network configuration of the GW-7553 must have the same domain and different IP with the PC (ex: PC’s IP=192.168.0.106, MASK=255.

5. GW-7553 module communication test This demo uses utility “MBTCP” on the PC to communicate with the GW7553. 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.

¾ 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 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.
