1. Introduction
PROFIBUS and HART are two kinds of famous protocols and are wildly used in the
fields of factory and process automation. The GW-7557 is a PROFIBUS to HART
gateway. By using this module, users can easily put the HART slave devices into
PROFIBUS network.
Figure 1
shows an application example for the GW-7557
module.

The GW-7557 gateway is specially designed for the slave device of PROFIBUS DP
protocol. In the HART application, the GW-7557 can be a HART master device. The
HART slave devices can exchange data with the PROFIBUS master device via the
GW-7557 module.
The main features and specification of GW-7557 are described as below:
