Getting Started

This guide discusses initial DeviceMaster Industrial Gateway installation and
hardware configuration for the DeviceMaster MOD and DeviceMaster UP
platforms.
The DeviceMaster Industrial Gateway is a network attached, solid-state device
server, which hosts an Industrial Ethernet engine and translates device
communications to a programmable logic controller (PLC) and any serial device.
This guide does not discuss configuring the port characteristics or protocol-specific
programming information. See
to locate the firmware and the appropriate documentation for your environment.
When a DeviceMaster MOD or DeviceMaster UP is loaded with the appropriate
firmware for your DeviceMaster Industrial Gateway, it enables connectivity
between any PLC and any serial device.
Note: The DeviceMaster MOD and DeviceMaster UP are often simply referred to
as the DeviceMaster in this User Guide.
Note: If you have a DeviceMaster MOD or DeviceMaster UP with 16-ports, use the
DeviceMaster UP 16-Port Hardware User Guide
connectors have different pin outs.
Depending on the model you purchased, the DeviceMaster MOD or DeviceMaster
UP may or may not have the specific Modbus protocol firmware loaded that fits
your environment.
The DeviceMaster MOD and DeviceMaster UP supports the following protocols:
• Modbus Router
• Modbus Server
• Modbus/TCP
Note: The default is Modbus Router. You can download either Modbus Server or
Modbus/TCP and load it onto the DeviceMaster MOD or DeviceMaster UP.
The Modbus Router application was designed to provide highly flexible and robust
connectivity for PLCs, SCADA systems, HMIs, OPC servers and applications that
require a wide range of Modbus connectivity options. Modbus Router provides
functionality such as:
• Master-to-master connectivity via the Shared Memory sub-system
• Private Modbus serial bus support designed to restrict access to private
Modbus devices
• Connectivity from serial Modbus masters to Modbus/TCP networks
• The ability to connect multiple types of Modbus masters to Modbus slave
device(s)
• Convert from one form of Modbus, such as Modbus/TCP, to Modbus/RTU or
Modbus/ASCII
• Provide connectivity from a serial Modbus master to a remote Modbus slave
device
