Overview
This section describes how to connect the Gateway to a host system and integrate data
gathered from the field device network. It covers network architectures, security, and data
mapping.
5.2
Network architecture
Physical connection types are important when determining the network architecture and what
protocols can be used for integration. Ethernet is the primary physical connection type and
RS485 is available an optional connection type. The following network architecture diagrams
will help when integrating data from the Gateway into the host system.
Ethernet
An Ethernet connection supports Modbus TCP, OPC, AMS Wireless Configurator, EtherNet/IP,
and HART TCP protocols. Using this connection type, the Gateway is wired directly to a control
network (see
for redundancy purposes.
