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.
