Important User Information

Solid state equipment has operational characteristics differing from those of

electromechanical equipment. Safety Guidelines for the Application, Installation and

Maintenance of Solid State Controls (publication SGI-1.1 available from your local

Rockwell Automation sales office or online at

http://literature.rockwellautomation.com) describes some important differences

between solid state equipment and hard-wired electromechanical devices. Because of

this difference, and also because of the wide variety of uses for solid state equipment,

all persons responsible for applying this equipment must satisfy themselves that each

intended application of this equipment is acceptable.

1-2 1756-DH485 Module Overview

Module Features

The 1756-DH-485 module offers the following features:

•Sends messages between devices on DH-485 networks and devices on

other networks such as ControlNet, EtherNet/IP, or other DH-485

networks

•Bridges support to other NetLinx networks via the CLX gateway

•Configure channels and ports using RSLinx Classic software, version

2.43 or later

•Accesses other networks by using a routing table editor that lets

DH-485 devices use the 1756-DH485 module and ControlLogix chassis

•Supports all benefits and attributes of a ControlLogix communication

module

•Supports firmware upgrades

•Removal and insertion under power (RIUP), can be removed and

inserted under power without disrupting power to other modules in the

chassis

•4-character display

•Default Controller Slot feature for local messaging

•Serial Port Configuration

•No limit on number of modules per chassis, up to the number of

available slots and the capabilities of the power supply

This figure shows the external features of the 1756-DH485 module.

TIP Download firmware upgrades via the backplane. Do

not use DH485 network for downloads.

WARNING

When you insert or remove the module while backplane

power is on, an electrical arc can occur. This could cause an

explosion in hazardous location installations.

Be sure that power is removed or the area is nonhazardous

before proceeding. Repeated electrical arcing causes

excessive wear to contacts on both the module and its

mating connector. Worn contacts may create electrical

resistance that can affect module operation.
