Compact™ Address Reserve Module
Module Description
Use the 1769-ARM address reserve module in CompactLogixTM systems to cost-effectively
reserve module slots. After creating the CompactLogix system’s I/O configuration and user
program, any I/O module in the system can be removed and replaced with a 1769-ARM
module once the removed module is inhibited using RSLogix 5000TM programming software.
Inhibiting a module creates an I/O configuration and user program removing all references
to that module.
To use the 1769-ARM module in MicroLogixTM systems, configure a generic module using
RSLogix 500TM programming software. Any user-program references to the slot position
occupied by the 1769-ARM module must not use another module’s parameters.

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.
(1)
Pollution Degree 2 is an environment where, normally, only non-conductive pollution occurs except that occasionally a
temporary conductivity caused by condensation shall be expected.
(2)
Over Voltage Category II is the load level section of the electrical distribution system. At this level transient voltages are
controlled and do not exceed the impulse voltage capability of the product’s insulation.
(3)
Pollution Degree 2 and Over Voltage Category II are International Electrotechnical Commission (IEC) designations.

1. Disconnect power.
ATTENTION
Remove power before removing or inserting this module. When you
remove or insert a module with power applied, an electrical arc may occur.
An electrical arc can cause personal injury or property damage by:
• sending an erroneous signal to your system’s field devices, causing
unintended machine motion
• causing an explosion in a hazardous environment
Electrical arcing causes excessive wear to contacts on both the module
and its mating connector. Worn contacts may create electrical resistance.
2. Check that the bus lever of the module to be installed is in the unlocked (fully right)
position.
3. Use the upper and lower tongue-and-groove slots (1) to secure the modules together
(or to a controller).
4. Move the module back along the tongue-and-groove slots until the bus connectors (2)
line up with each other.
5. Push the bus lever back slightly to clear the positioning tab (3). Use your fingers or a
small screw driver.

6. To allow communication between the controller and module, move the bus lever fully
to the left (4) until it clicks. Ensure it is locked firmly in place.
When attaching I/O modules, it is very important that the bus
connectors are securely locked together to ensure proper
electrical connection.
ATTENTION
7. Attach an end cap terminator (5) to the last module in the system by using the
tongue-and-groove slots as before.
8. Lock the end cap bus terminator (6).
IMPORTANT
A 1769-ECR or 1769-ECL right or left end cap must be used to terminate
the end of the serial communication bus.
Mounting Expansion I/O
ATTENTION
During panel or DIN rail mounting of all devices, be sure that all debris
(metal chips, wire strands, etc.) is kept from falling into the module.
Debris that falls into the module could cause damage on power up.

±0.4 mm (0.016 in.)
Panel Mounting Procedure Using Modules as a Template
The following procedure lets you use the assembled modules as a template for drilling holes
in the panel. Due to module mounting hole tolerance, it is important to follow these
procedures.
1. On a clean work surface, assemble no more than three modules.
2. Using the assembled modules as a template, carefully mark the center of all
module-mounting holes on the panel.
3. Return the assembled modules to the clean work surface, including any previously
mounted modules.
4. Drill and tap the mounting holes for the recommended M4 or #8 screw.
5. Place the modules back on the panel, and check for proper hole alignment.
6. Attach the modules to the panel using the mounting screws.
If mounting more modules, mount only the last one of this group and put the others
aside. This reduces remounting time during drilling and tapping of the next group.
7. Repeat steps 1 to 6 for any remaining modules.

DIN Rail Mounting
The module can be mounted using these DIN rails:
• 35 x 7.5 mm (EN 50022 - 35 x 7.5)
• 35 x 15 mm (EN 50022 - 35 x 15)
Before mounting the module on a DIN rail, close the DIN rail latches. Press the DIN rail
mounting area of the module against the DIN rail. The latches will momentarily open and
lock into place.
Replacing a Single Module within a System
The module can be replaced while the system is mounted to a panel (or DIN rail).
1. Remove power.
ATTENTION
Remove power before removing or inserting this module. When you
remove or insert a module with power applied, an electrical arc may occur.
An electrical arc can cause personal injury or property damage by:
• sending an erroneous signal to your system’s field devices, causing
unintended machine motion
• causing an explosion in a hazardous environment
Electrical arcing causes excessive wear to contacts on both the module
and its mating connector. Worn contacts may create electrical resistance.
2. On the module to be removed, remove the upper and lower mounting screws from
the module (or open the DIN latches using a flat-blade or phillips style screw driver).
3. Move the bus lever to the right to disconnect (unlock) the bus.
4. On the right-side adjacent module, move its bus lever to the right (unlock) to
disconnect it from the module to be removed.
5. Gently slide the disconnected module forward. If you feel excessive resistance, check
that the module has been disconnected from the bus, and that both mounting screws
have been removed (or DIN latches opened).
It may be necessary to rock the module slightly from front to back to remove it, or, in
a panel-mounted system, to loosen the screws of adjacent modules.
6. Before installing the replacement module, be sure that the bus lever on the module to
be installed, and on the right-side adjacent module are in the unlocked (fully right)
position.
