8.6.12 Modbus RTU Slave

Modbus RTU Slave can be configured on either RS-485 port by selecting
Modbus RTU Slave from the protocol dropdown menu. By default, the
gateway's entire database is accessible via the register mapping mechanism
discussed in section 9.9.2.2.
8.6.12.1 Protocol Selection Group
Protocol
Select Modbus RTU Slave from this dropdown menu.
Baud Rate
Select the desired network baud rate from this dropdown menu.
Parity
Select the desired network parity and number of stop bits from this dropdown
menu.
Address
This field is the slave address at which the device will reside on the network.
Enter a value between 1 and 247.
Timeout Time
Refer to section 8.2.1.
Response Delay
This field is used to set the time, in milliseconds, the device waits before
responding to master requests. This may be useful if the Modbus master
communicating to the gateway requires additional time before it can process a
response to its request. If no delay is required, set this field to 0.
8.6.12.2 Register Remap Object
Optionally, registers can be remapped to different database addresses from their
default mapping using a register remap object. It also allows the user to map a
register that is not mapped into the database by default (any register above 2048)
to an address in the database. The register remap object can remap a range of
consecutive registers to any starting address in the database (as long as the
entire range is within the database).
Note that registers can be accessed as either holding registers or input registers.
Accessing either type refers to the same register on the gateway.
The following describes the configurable fields for a register remap object. For
more information on register remap object editing options, refer to section 8.5.
