If a packet contains a Modbus server address above the amount entered here, the address
will be adjusted downward by this amount before the packet is delivered. This allows you
to configure clients on the gateway that will forward messages to remote devices with the
same Modbus address on different buses. For example, if there are two devices on two
different buses that have the same Modbus address of 10, you can create two clients on
the gateway:
n
Client one:
l
filter
set to
10
.
This will configure the gateway to deliver all messages that have the Modbus server
address of 10 to this device.
n
Client two:
l
filter
set to
20
.
l
adjust_server_address
set to
10
.
This will configure the gateway to deliver all messages that have the Modbus server
address address of 20 to the device with address 10.
