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-7553-B / GW-7553-M is a
PROFIBUS to Modbus TCP gateway. By using this module, users can easily put the
Modbus TCP devices into PROFIBUS network.
Figure 1
shows an application example for the GW-7553-B / GW-7553-M module.
Figure 1 Application architecture of the GW-7553-B / GW-7553-M module
The GW-7553-B / GW-7553-M Gateway is specially designed for the slave device of
PROFIBUS DP protocol. In the Modbus protocol application, the GW-7553-B / GW-
7553-M can be a Modbus Master device or Slave device. The Modbus devices can
exchange data with the PROFIBUS Master device via the GW-7553-B / GW-7553-M
module.
