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:

Client one:

filter set to 10.

This will configure the gateway to deliver all messages that have the Modbus server

address of 10 to this device.

Client two:

filter set to 20.

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.
