Using SmartWire-DT on Modbus TCP Ethernet via the EU5C-
SWD-EIP-MODTCP Gateway and the ELC-COENETM Modbus
TCP Master
The Eaton ELC-PV28 controller with the ELC-COENETM Modbus TCP master
module may be used to control and monitor a SmartWire-DT system via the
EU5C-SWD-EIP-MODTCP Ethernet gateway. The SmartWire-DT gateway is a
node on Modbus TCP and a master on the SmartWire-DT network. The data for
each SmartWire-DT device connected to the gateway is mapped to the Input and
Output images in the gateway. This is what the Modbus TCP master reads and
writes from/to the gateway.
In SWD-Assist in the offline mode the SmartWire-DT gateway will display the
total number of input and output bytes mapped to accommodate the data from all
of the SmartWire-DT devices connected to it. Click the gateway in the offline
mode to select it. Then select the SWD Information tab and the following will be
displayed:
In the lower portion of the window the information in the table below will be
displayed. This confirms the total number of devices attached to the gateway and
also provides the total number of input and output bytes mapped to it for these
devices. SmartWire-DT is byte based while Modbus TCP is based on 16-bit
