BURN 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://www.rockwellautomation.com/literature/) 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.

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 Group 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.

Preventing Electrostatic Discharge

This equipment is sensitive to electrostatic discharge, 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.

Mount the I/O Base

To mount the ArmorPOINT I/O base on a wall or panel, use the screw holes provided in the ArmorPOINT base.

The ArmorPOINT I/O module must be mounted on a grounded metal mounting plate or other conductive surface.

A mounting illustration for the ArmorPOINT base with an adapter is shown below.

Install the mounting base as follows:

1. Lay out the required points as shown above in the drilling dimension

drawing.

2. Drill the necessary holes for #8 (M4) machine or self-tapping screws.

3. Mount the base using #8 (M4) screws.

4. Ground the system using the ground lug connection. (The ground lug

connection is also a mounting hole.)

Install the ArmorPOINT Very High Speed Counter Module

To install the ArmorPOINT Very High Speed Counter module, proceed as follows.

1. Using a bladed screwdriver, rotate the keyswitch on the mounting base

clockwise until the number 2 aligns with the notch in the base.

2. Position the module vertically above the mounting base. The module

will bridge two bases.

3. Push the module down until it engages the latching mechanism. You will

hear a clicking sound when the module is properly engaged.

The locking mechanism will lock the module to the base.

Remove the ArmorPOINT Very High Speed Counter Module From the Mounting Base

To remove the module from the mounting base:

1. Put a flat blade screwdriver into the slot of the orange latching

mechanism.

2. Push the screwdriver toward the I/O module to disengage the latch.

The module will lift up off the base.

3. Pull the module off of the base.

Communicate With Your Module

I/O messages are sent to (consumed) and received from (produced) the ArmorPOINT I/O modules. These messages are mapped into the processor’s memory. This ArmorPOINT I/O input/output module produces 6 or 10 bytes of input data (scanner Rx - status). It consumes 2 or 4 bytes of I/O data (scanner Tx). See the 1738 ArmorPOINT adapter User Manual, publication

1734-UM016, for specific parameter information.

Note that when a configuration is sent to the module, it is checked for consistency before being applied. If an error is found in the configuration, the PE bit is asserted and the module retains its previous configuration. Monitor this PE bit with your user program to isolate any problems an improperly configured module may have. If the configuration is considered acceptable, the counter ASIC is disabled, counting is suspended, and outputs are shut off while the ASIC is loaded with the new operational parameters.
