Figure D-5. Simplex RS-485 Architecture

Note

In either a simplex or dual RS-485 architecture, the primary Ethernet ports can be connected to

an asset management network to provide connectivity to AMS Device Manager or AMS Wireless

Configurator.

Dual RS-485

A Dual RS-485 host connection support Modbus RTU protocol. When using this architecture,

connect the secondary Ethernet port on Gateway A directly to the secondary Ethernet port on

Gateway B. Then wire the RS-485 ports for both Gateways separately to dual serial cards at the

host system. See Figure D-6 Dual RS-485 Architecture.

A. Engineering Station

B. Process Control Network
