1. Introduction
Profibus and Modbus are two kinds of famous protocols and are wildly used in the
fields of factory and process automation. The GW-7552-B / GW-7552-M is a
Profibus to Modbus gateway. By using this module, users can easily put the Modbus
devices into Profibus network.
Figure 1
shows an application example for the GW-7552-B / GW-7552-M module.

The GW-7552-B / GW-7552-M Gateway is specially designed for the slave device of
PROFIBUS DP protocol. In the Modbus protocol application, the GW-7552-B / GW-
7552-M can be a Modbus master device or slave device. The Modbus devices can
exchange data with the Profibus master device via the GW-7552-B / GW-7552-M
module.
