4.1 Summary
The section is about how to connect gateway and PC system, and integrate collected data from
field device network, covering network structure, security ability and data mapping.
4.2 Network Structure
When the user is determining the network structure and protocol to integrate, the physical
connection type is pretty important. Ethernet is the primary physical connection type, and RS-485
can be used as the optional one. When the sub-gateway is sending integrate data to host system,
and the network structure in
Figure 4-1
is helpful.
If the user has higher security requirements, the user shall connect WirelessHART gateway to PC
system via LAN (rather than WAN)
Ethernet
Ethernet connection supports Modbus TCP and private protocols. With this connection type, the
gateway shall connect to control system via network interchanger, router or concentrator directly.

RS485 (Serial)
RS485 connection supports Modbus RTU protocol. With this connection type, gateway shall
