Modbus to PROFIBUS DP Converter GT100-DP-RS in Large Ports and Wharf
|
|
Background |
As the LED
display has many advantages, like high brightness, long life, strong
light penetration, clearly visible under strong light, it is widely
used in many areas, such as the sea ports, building, traffic
information display.
The company used the LED display in a driving control prompt system
of a large port engineering locomotive. The console of the entire
system is the Siemens 300 PLC, the customer needs to achieve the
data transmission between console PLC and LED screen. LED support
RS485 serial communication.
The display shows the content information sent by the console in
order to remind the scene of the locomotive driving direction and
the staff attention to safety.

| Solution |
In a variety
of large ports and terminals, engineering locomotives and cranes
need to load and unload cargo and containers, because the site
environment is more complex, system center needs unified schedule.
In the master control room, using Siemens 300PLC and SST Automation GT100-DP-RS
converter, which send instructions to the LED display and show the
received instructions.
According to the instructions displayed on the LED that sent by the
master control room, engineering vehicles and cranes load and unload
cargos with direction and remind the site staff pay attention to
safety and release notice, greatly improving the efficiency of
the port and the terminal. |

| Summary |
| In this
control system, SST Automation converter GT100-DP-RS
woks as a bridge between LED display screen and Siemens PLC S7-300,
which enable fieldbus equipment of two different protocols achieve
data communication, make it possible that PLC console can send data
to the LED. In the whole system, the converter GT100-DP-RS of
SST Automation demonstrates its stability, reliable capability,
provides a good guarantee for the entire control system can run
well. |
