7.4.1 EXAMPLE OF MODBUS GATEWAY SETTINGS.
Index 1 is receiving modbus requests from the external monitoring system on Ethernet, TCP Port 502.
This is being transferred to the DSE controller via the USB Host port on the DSEGateway
®
Index 2 is receiving modbus requests from the external monitoring system on Ethernet, TCP Port 503.
This is being transferred to the DSE controller via the RS485 port on the DSEGateway
®
using slave ID
2, baud rate 115200.
Index 3 is receiving modbus requests from the external monitoring system on Ethernet, TCP Port 504.
This is being transferred to the DSE controller via the RS232 port on the DSEGateway
®
using slave ID
10, baud rate 115200.
NOTE: RS485 is a single master system. This means that you must only create one entry
for RS485 in the Slave column. Each entry in the Master column must communicate with
controllers with unique Slave Id’s.
NOTE: RS232 is a single master, single slave system. This means that you must only
create one entry for the RS232 in the Master and Slave columns.
NOTE: Where multiple Ethernet connections are configured, each must utilise a unique
port number.
Slave : The port connected to
the monitoring system
Master : The port connected
to the DSE controller
