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 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 module.
Figure 1 Application architecture of the GW-7553 module
The GW-7553 Gateway is specially designed for the slave device of PROFIBUS DP
protocol. In the Modbus protocol application, the GW-7553 can be a Modbus Master
device or Slave device. The Modbus devices can exchange data with the PROFIBUS
Master device via the GW-7553 module.
The main features and specification of GW-7553 are described as below:
