LED Indicator
The GW-7552-M module provides three LED indicators, Including
indicators for power status and connecting status. The following is an
overview of the purpose and function of each LED indicator together with
a description.
LED Name
LED
Status
LED Description
PWR
Flash
When the GW-7552-M acts as a Modbus slave
device and receiving query message form
Modbus master device, PWR led will flash.
On
Power supply ok.
The firmware has loaded.
Off
Power supply has failed
ERR
Flash
When the GW-7552-M connects with the utility
tool, it will flash fast (flash once about 55ms).
When the GW-7552-M has diagnostic message,
it will flash slowly (flash once about 220ms).
On
Connection error between Profibus master and
slave or Profibus system has not been configured
correctly.
Off
Normal operation
PROFIBUS system has been configured correctly
RUN
On
Data exchange mode
Normal operation.
Off
GW-7552-M module is not in a data exchange
mode.
Wiring and Jumper
The GW-7552-M module supports PROFIBUS to Serial Port
communication. It is recommended to use only one serial port (RS232,
RS485 or RS422) of the Gateway at the same time. User may need to
adjust the internal jumpers. (Refer to manual 2.3)

Terminal Resistor
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. A
standard PROFIBUS connector is usually
already equipped with a terminal resistor.
PROFIBUS Connector
The number of stations in a PROFIBUS network is restricted to 126.
According to the PROFIBUS specification up to 32 stations are allowed
per segment. A repeater has to be used to link the bus segments.
DIP SWITCH Address Setting
The GW-7552-M module can be set by using either the dip switch or by
writing it directly to the EEPROM. The dip switch covers a range from 0 to
255. The valid address
range of a Profibus station
spans from 0 to 126. (Refer
to manual 2.6)
DIP SWITCH
Station address
Description
0~125
1. The address setting of the EEPROM is ignored.
2. The address cannot be set by the PROFIBUS configuration tool.
126
1. The address setting of the dip switch is ignored.
2. If the address in the EEPROM is 126, the PROFIBUS
configuration tool can set a new address and save it to the
EEPROM.
255
Slave address in the EEPROM is set to 126.
More information about GW-7552-M module, please refer to manual.
