14. For
Fixed Modbus server address
, if request messages handled by this client should always
be forwarded to a specific device, type the device's Modbus address. Leave at the default
setting of
0
to allow messages that match the
Modbus address filter
to be forwarded to
devices based on the Modbuss address in the message.
15. For
Adjust Modbus server address
, type a value to adjust the Modbus server address
downward by the specified value prior to delivering the message. Allowed values are
0
through
255
. Leave at the default setting of
0
to not adjust the server address.
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
Modbus address 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
Modbus address filter
set to
20
.
l
Adjust Modbus 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.
16. Repeat these steps to configure additional clients.
