ArmorPoint ControlNet Adapter, Series A

Catalog Number 1738-ACNR

The ArmorPoint ControlNet adapter ships with the adapter and a
terminating base to be used with the last I/O module on the
backplane. The sealed IP67 housing of the adapter requires no
enclosure. (Note that environmental requirements other than IP67
may require an additional appropriate housing.) ControlNet
connectors are two redundant TNC style network connectors a nd one
mini style power connector. The ArmorPoint ControlNet adapter is
shown below.

SHOCK HAZARD

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.

In no event will Rockwell Automation, Inc. be responsible or liable for
indirect or consequential damages resulting from the use or application of
this equipment.

The examples and diagrams in this manual are included solely for illustrative
purposes. Because of the many variables and requirements associated with
any particular installation, Rockwell Automation, Inc. cannot assume
responsibility or liability for actual use based on the examples and diagrams.

No patent liability is assumed by Rockwell Automation, Inc. with respect to
use of information, circuits, equipment, or software described in this manual.

Reproduction of the contents of this manual, in whole or in part, without

ATTENTION

Environment and Enclosure

This equipment is intended for use in overvoltage
Category II applications (as defined in IEC
publication 60664-1), at altitudes up to 2000 meters
without derating.

This equipment is considered Grou p 1, Class A
industrial equipment according to IEC/CISPR
Publication 11. Without appropriate precautions,
there may be potential difficulties ensuring
electromagnetic compatibility in other environments
due to conducted as well as radiated disturbance.

This equipment is supplied as "enclosed" equipment.
It should not require additional system enclosure
when used in locations consistent with the enclosure
type ratings stated in the Specifications section of this
publication. Subsequent sections of this publication
may contain additional information regarding
specific enclosure type ratings, beyond what this
product provides, that are required to comply with
certain product safety certifications.

NOTE: See NEMA Standards publication 250 and IEC
publication 60529, as applicable, for explanations of
the degrees of protection provided by different types
of enclosure. Also, see the appropriate sections in
this publication, as well as the Allen-Bradley
publication 1770-4.1 ("Industrial Automation Wiring
and Grounding Guidelines"), for additional
installation requirements pertaining to this
equipment.

Before You Begin

ATTENTION

To effectively use your adapter, note the following considerations.

Preventing Electrostatic Discharge

This equipment is sensitive to electrostatic dischar ge,
which can cause internal damage and affect normal
operation. Follow these guidelines when you handle
this equipment:

• Touch a grounded object to discharge potential
static.

• Wear an approved grounding wriststrap.

• Do not touch connectors or pins on component

boards.

• Do not touch circuit components inside the
equipment.

• If available, use a static-safe workstation.

• When not in use, store the equipment in

appropriate static-safe packaging.

Understand Messaging

Class 3 (Explicit Message) requests through the adapter to a specific
I/O module may not always receive a response from the I/O module.
In the case where the I/O module does not reply to the request, the
adapter responds with an error code indicating a time-out.

Establish I/O Connections

When you power up a ArmorPoint I/O system and establish I/O
connections, the outputs transition to the Idle state, applying Idle state
data before going to RUN mode. This occurs even when the controller
making the connection is already in RUN mode.

Configure Autobaud

The adapter cannot reconfigure an I/O module that you previously
configured to operate at a fixed baud rate. When you reuse a
ArmorPoint I/O module from another ArmorPoint I/O system,
configure the module to autobaud before using it with the adapter.
