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.
Figure 1 Application architecture of 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:

2.3 Wiring
GW-7557 supports PROFIBUS to HART communication. The following section
describes the connection interface of GW-7557.
2.3.1 RS-232 connection
The RS-232 port of the GW-7557 has got three pins. The wiring of the RS-232
device with the RS-232 port of the GW-7557 is shown in Figure 4.

2.3.2 PROFIBUS connection
The PROFIBUS interface of the GW-7557 is a DB9 female connector. The
connector uses the standard PROFIBUS 9 pin assignment. It is recommended to
use a standard PROFIBUS cable and connector (DB9 male). As with every
serial bus the rate of safe data transmission in a PROFIBUS network decreases
with increasing distance between Master and Slave. Table 4 shows the
transmission rate and range for a cable with the following properties:
1. Impedance :135~165 Ω
2. Capacity : lower than 30 pF/m
3. Loop resistance : lower than 110 Ω/km
4. Wire diameter : greater than 0.65 mm
5. Core cross-section : greater than 0.34 mm2

Table 4 Transmission rate decreasing with increasing transmission distance
Transmission Rate(kbps) Transmission Distance per Segment (meter)
9.6, 19.2, 45.45,93.75 1200
187.5 1000
500 400
1500 200
3000, 6000, 12000 100
In order to minimize the reflection effect of signal transmission, both ends (first
node and last node) of a PROFIBUS segment needs to be equipped with an
active terminal resistor as shown in Figure 5. A standard PROFIBUS connector
is usually already equipped with a terminal resistor. The user therefore only has
to switch on the resistor of the devices stationed at the ends of a segment as
shown in Figure 6.
