5 Operation and maintenance
5.1 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
usable protocols for integration. Ethernet is the primary physical connection type; RS485
is also available. 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 Figure 5-1) using a network switch, router, or hub. Often
there are two networks for redundancy purposes.
