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 "open type" equipment. It
must be mounted within an enclosure that is suitably
designed for those specific environmental conditions that
will be present and appropriately designed to prevent
personal injury resulting from accessibility to live parts.
The interior of the enclosure must be accessible only by
the use of a tool. Subsequent sections of this publication
may contain additional information regarding specific
enclosure type ratings that are required to comply with
certain product safety certifications.
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.

ATTENTION
This product is grounded through the DIN rail to chassis
ground. Use zinc plated, yellow chromated steel DIN rail
to assure proper grounding. Using other DIN rail
materials (e.g. aluminum, plastic, etc.) which can corrode,
oxidize or are poor conductors can result in improper or
intermittent platform grounding.
Install the Mounting Base
To install the mounting base on the DIN rail, proceed as follows.
1. Position the mounting base vertically above the installed units
(adapter, power supply or existing module.
2. Slide the mounting base down allowing the interlocking side pieces to
engage the adjacent module or adapter.
3. Press firmly to seat the mounting base on the DIN rail. The mounting
base will snap into place.
4. To remove the mounting base from the DIN rail, remove the module,
and use a small bladed screwdriver to rotate the base locking screw to
a vertical position. This releases the locking mechanism. Then lift
straight up to remove.
Install the I/O Address Reserve Module
Use the 1734-ARM address reserve module to retain a node address for later
insertion of any future option. It can be installed in any slot with any key
position. However, we recommend that the key position be that of the
module that is intended to be installed in that position at a later date.
The module can be installed before, or after base installation. Make sure that
the mounting base is correctly keyed before installing the module into the
mounting base. In addition, make sure the mounting base locking screw is
positioned horizontal referenced to the base.
Publication 1734-IN019A-EN-E - May 2005
POINT I/O Address Reserve Module 7
WARNING
1. Using a bladed screwdriver, rotate the keyswitch (2) on the mounting
base clockwise until the number required for the type of module being
installed aligns with the notch in the base.
2. Make certain the DIN rail locking screw is in the horizontal position.
(You cannot insert the module if the locking mechanism is unlocked.)
3. Insert the module straight down into the mounting base and press to
secure. The module will lock into place.
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.
Install the Removable Terminal Block (RTB)
A removable terminal block is supplied with your wiring base assembly. To
remove, pull up on the RTB handle. This allows the mounting base to be
removed and replaced as necessary without removing any of the wiring. To
reinsert the removable terminal block, proceed as follows.
1. Insert the end opposite the handle into the base unit. This end has a
curved section that engages with the wiring base.
2. Rotate the terminal block into the wiring base until it locks itself in
place.
3. If an I/O module is installed, snap the RTB handle into place on the
module.

WARNING
5. Repeat steps 1, 2, 3 and 4 for the module to the right.
6. Use a small bladed screwdriver to rotate the orange base locking
screw to a vertical position. This releases the locking mechanism.
7. Then lift straight up to remove.
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.

Communicate with Your Module
I/O messages are sent to (consumed) and received from (produced) the
POINT I/O modules. These messages are mapped into the processor’s
memory. This POINT I/O address reserve module produces one byte of I/O
data. It does not consume I/O data.

Wire the Address Reserve Module
The address reserve module requires no external wiring.
Use the Address Reserve Module
After creating the ControlLogix or CompactLogix systems I/O configuration
and user program, any I/O module in your system can be removed and
replaced by an address reserve module once the removed module is inhibited
using RSLogix 5000 programming software.
Inhibiting a module creates an I/O configuration and user program removing
all references to that module.
To use a 1734-ARM module in a MicroLogix system, configure a generic
module using RSLogix 500 programming software. Any user program
references to the slot position occupied by the 1734-ARM module must not
use another module’s parameters.
ATTENTION
Use the RSLogix 5000 program software to inhibit the
1734-ARM module or the I/O module replaced by the
1734-ARM module. Failure to do so will result in the
controller continually trying to connect to a
noncommunicating module, thereby wasting connections.
