GW-7552 PRIFIBUS/MODBUS GATEWAY
Quick Start User Guide
1. Introduction
This manual introduces the GW-7552'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-7552\ manual\GW-7552 user manual.pdf").
This manual helps users to understand about the GW-7552 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
In this example the GW-7552 acts as a Modbus slave device. When the GW-7552
module receives a write DO Modbus command from PC's COM Port, the GW-7552
module can send the message to the input data area of PROFIBUS master station.
When the GW-7552 module receives a read DI Modbus command from PC's COM
Port, GW-7552 module can refer to the output data area of PROFIBUS master
station to produce response message and send it to PC's COM Port.

Hilscher. Application example of PROFIBUS to Modbus In this example the GW-7552 acts as a Modbus slave device. When the GW-7552 module receives a write DO Modbus command from PC’s COM Port, the GW-7552 module can send the message to the input data area of PROFIBUS master station. - Page 2 The GW-7552 is a slave device of PROFIBUS DP protocol. The station address of GW-7552 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-7552 module’s dip switch to 1.
