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
Configurator, EtherNet/IP,
Gateway is wired directly to a control network (see
router, or hub. Often there are two networks for redundancy purposes.

RS485 (serial)
An RS485 connection supports Modbus RTU protocol. Using this connection type, the
Gateway is wired to an RS485 bus which typically leads to a serial I/O card or Modbus I/O
