Environment and Enclosure
ATTENTION: This equipment is intended for use in a Pollution Degree 2
industrial environment, in overvoltage Category II applications (as defined in
IEC publication 60664-1), at altitudes up to 2000 meters (6562 ft)
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 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 enclosure must have
suitable flame-retardant properties to prevent or minimize the spread of flame,
complying with a flame spread rating of 5VA, V2, V1, V0 (or equivalent) if
non-metallic. 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.
In addition to this publication, see:
•Industrial Automation Wiring and Grounding Guidelines, for additional
installation requirements, Allen-Bradley publication 1770-4.1
•NEMA Standards publication 250 and IEC publication 60529, as
applicable, for explanations of the degrees of protection provided by
different types of enclosure.
Prevent Electrostatic Discharge
ATTENTION: 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.
•Use a static-safe workstation, if available.
•Store the equipment in appropriate static-safe packaging when not in use.

Before You Begin
Read this section about important CompactBlock I/O requirements.
Current functions of CompactBlock LDX I/O blocks require the current, modular
electronic data sheet (EDS) file for RSNetWorx for DeviceNet software, version 8.0 or
later. These files are are available online at http://www.ab.com/networks/eds/
EDS files for blocks with matching catalog numbers for both D-shell and terminal block
versions are the same. On the website and in RSNetWorx for DeviceNet software,ind the
EDS file for both versions of the blocks. For example, for the EDS file for 1790D-T8BV8B
blocks, use the EDS file labelled 1790D-8BV8B.

Example: Node
Address is set at 11
Install the Base Block
To install the base block:
•set the node address on the base block.
•mount the base block.
•mount the optional expansion blocks.
•wire the terminal block.
•connect the DeviceNet cable.
Set the Node Address on the Base Block
When setting the node address on the base block, note that each base block comes with its
internal program set for node address 63. To reset the node address, adjust the switches on
the front of the base block. The two switches are most significant digit (MSD) and least
significant digit (LSD). You can set switches to 00...63.
Node Address Example
The base block reads the rotary switches at power up only. Switch settings between 64 and
99 cause the block to use the last valid node address stored internally.
You can also set the node address through RSNetWorx for DeviceNet software or a similar
configuration tool.
When you use software configuration for the node address, set the switches to 64…99.

For panel mounting, use these steps.
1.Place the block against the panel where you want it mounted.
2.Gently pull and position the expansion cover to the left.
3.Place a center punch, nail, or similar device through the mounting holes in the
block and make two marks on the panel at the lower-left and upper-right corners
of the module.
4.Remove the block and drill two holes in the panel to accommodate each of the
mounting screws.
5.Replace the block on the panel and place a screw through each of the two
mounting holes.
6.Tighten the screws until the block is firmly in place.
Mount on DIN Rail
For DIN-rail mounting, use these steps.
1.Hook the top slot of the base block over the DIN rail.
2.Pull down on the locking lever while pressing the base block against the rail.
3.Push up on the locking lever to secure the base block to the rail when the base
block is flush against the rail.

2.Beginning with the base block, mount your expansion block either horizontally
or vertically.
•To mount horizontally (left to right), add an expansion block in an
end-to-end configuration.
•To mount vertically (up or down), add an expansion block either up or down
in a back-to-back configuration. In this configuration, you must use the
optional 15 cm (5.9 in.) ribbon cable, catalog number 1790-15CMCBL, and
alternately position the block in a right-side up, upside-down fashion.
3.Mount your block on a panel or DIN rail.

Connect the DeviceNet Cable
Follow these procedures to connect the DeviceNet cable to the base block. The DeviceNet
connector is not supplied with the base block. You must purchase the connector separately.
These are the types of connectors you order directly from Rockwell Automation.
•1799-DNETCON – 5-position open-style connector
•1799-DNETSCON – 5-position open-style connector with locking screws
•1799-DNC5MMS – 5-position open-style to 12 mm (0.47 in.) connector with
locking screws
WARNING: If you connect or disconnect the communication cable with
power applied to this module or any device on the network, 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
1.Connect the DeviceNet wiring (drop line) to one of the DeviceNet connectors as
shown in the figure, noting that a color-coded wiring diagram is printed next to
the connector on the left side of the base block.
1.Attach the connector to the base block once you have properly wired
the drop line to the connector.
2.Use the locking screws on the connector to fasten it to the base block,

Cable Break Procedures
A cable break in any location between either of the following produces data of 0 in the data
table for all inputs down stream of the cable break:
•Base and digital input expansion module
•Digital input expansion module and another digital input expansion module
All digital-expansion inputs produce data of 0 if the expansion cable is removed. No status
is in the default produced assembly. Attribute 101 in the identity object reports module
faults.
If no faults are present, an explicit message GET command returns 0.
If the ribbon cable is disconnected, it returns 0x04, which is for module location change.
The module status indicator also flashes indicating a fault if an expansion is disconnected.
Select an alternate produced assembly that contains the expansion status byte, using the
EDS Properties configuration dialog.
