System Compatibility
CompactBlock I/O modules are compatible with PLC, SLC or
SoftLogix programmable controllers when used with DeviceNet
scanners.
CompactBlock Family
Module Communication
The CompactBlock modules act as a slave in a master/slave
environment. Their I/O data is exchanged with the master through a
polled, cyclic, or change-of-state connection. This selection is made in
the DeviceNet scanner module’s configuration.
Polled
When configured as a polled device, a master initiates communication
by sending its polled I/O message to the CompactBlock module.
Cyclic
When using cyclic operation, the master only sends data to the
CompactBlock I/O module and only receives data from the module at
a preconfigured time interval.
Change-of-State
When the CompactBlock I/O module is configured for
change-of-state, the master only sends output data when:
• the user’s control program wants to update the module’s output
• the time period for communication has expired
Publication 1791D-TD001D-EP - October 2002
4
Overview
CompactBlock I/O for DeviceNet
The CompactBlock module’s input data is only sent to the master
when:
• an input changes
• the time period for communication has expired
With change-of-state, the master does not have to request input data
from the slave, it is sent automatically when data changes. In
addition, an adjustable "heartbeat" is produced periodically by the
CompactBlock module to let the consuming device know that the
module connection is alive and ready to communicate.
Input Filtering
Input filtering limits the effect of voltage transients caused by contact
bounce and/or electrical noise. If not filtered, voltage transients could
produce false data.
To configure an input filter, an input signal delay is set to turn
off-to-on or on-to-off for nominal amounts of time. The mode and
filter time is set through RSNetworx for DeviceNet software, or a
similar configuration tool.
Idle and Fault
Mode Selection
When the PLC, SLC or PC-based programmable controller is in
program mode, the DeviceNet scanner puts the CompactBlock
module in an idle state. If the DeviceNet scanner drops off the
network, the module goes to a fault state.
In both idle and fault states, the module resets its outputs by default.
You can use RSNetworx for DeviceNet software or a similar
configuration tool to change the default and set the module to save
the last received outputs.
Fault
State
hold last state (HLS)
HLS
use fault value
0
Fault
Value
apply 0 to output
1
apply 1 to output
Fault state can be set to HLS or use fault value. The fault value can be set to 0 or 1.
The same logic applies for idle conditions.
DeviceLogix Functionality
Publication 1791D-TD001D-EP - October 2002
42455
The CompactBlock I/O family also offers modules that have
DeviceLogix, a local logic capability that provides you with the ability
to control outputs and manage status information locally, within the
device. DeviceLogix is configured through a Function Block Editor
that is accessed through RSNetWorx for DeviceNet. This editor lets
CompactBlock I/O for DeviceNet
Overview

you create local logic using boolean logic (AND, OR, etc.), set and
reset latches as well as a variety of timers and counters. User support
for the editor can be found in the DeviceLogix Users Manual and
online help.
CompactBlock products that support DeviceLogix have some
device-specific capabilities and capacities, which are identified in the
following table.

The DeviceLogix-capable versions of CompactBlock I/O give you the
ability to choose how much data the modules produce or consume
over DeviceNet. Two new parameters have been added to the EDS
files that let you select the amount of data that will be transmitted or
received.
Produced I/O Assembly
There are three options for Produced Data:
• Default assembly - Produces the device’s input data and any
fault/status data the device has.
• Input only assembly - Produces only the state of the device’s
inputs. This lets those who do not make use of the Diagnostic bits
reduce their network traffic.
Publication 1791D-TD001D-EP - October 2002

Overview
CompactBlock I/O for DeviceNet
• DeviceLogix assembly - Produces all of the standard information
from the Default assembly plus the data that is available as a result
of invoking DeviceLogix.
The new DeviceLogix data that is available includes:
– Logic Enabled bit - This bit is high when DeviceLogix is
running on a device and has been enabled. This can be used,
for example, in the PLC program or on a DeviceNet MMI to
indicate the presence of local logic control.
– Network Output bits - These bits are used in the DeviceLogix
configuration to send information back over the network. For
example, the output of any Function Block can be connected to
a network output bit.
– Hardware Output bits - DeviceLogix lets you locally control
the state of hardware outputs. Therefore these bits are
produced by the device so that the state of the outputs can be
sent back to the network master. If an output in the device is
not under DeviceLogix control, its status is still controlled by
the normal consumed data.
The assemblies for CompactBlock I/O devices are listed in the
sections that contain specific module information. Please refer to
the Specific Module Information section, page 10, for a guide
to specific module information.
Consumed I/O Assembly
DeviceLogix provides the device the ability to consume data from the
DeviceNet master other than the normal state of the hardware
outputs. This data is called Network Input Bits. Up to 32 of these bits
can be consumed by the device. Five options exist for the variable
amount of consumed data: 0, 1, 2, 3, or 4 bytes. A standard 16 output
CompactBlock I/O module, for instance, consumes 16 bits (2 bytes).
With DeviceLogix, you can choose to consume an additional 2 bytes
of Network Inputs. If a hardware output is controlled by local logic,
its state is no longer consumed and that bit becomes available to be
used as a Network Input. For more on this concept, please see the
DeviceLogix User Manual.

The CompactBlock base module I/O is exchanged
with the master through a poll, change-of-state, or
cyclic connection.
The module produces 1 byte for every 8 inputs.
Similarly, the module consumes 1 byte for every 8
outputs. When an expansion module is connected,
it returns an additional byte indicating the health of
the expansion module. For the Input Status bits,
when the bit is set (1), the input is on. For the
Output bits, when the bit is set (1), the output is
on.

The CompactBlock base module I/O is exchanged
with the master through a poll, change-of-state, or
cyclic connection.
The module produces 1 byte for every 8 inputs.
Similarly, the module consumes 1 byte for every 8
outputs. When an expansion module is connected,
it returns an additional byte indicating the health of
the expansion module. For Input Status bits, when
the bit is set (1), the input is on. For Output bits,
when the bit is set (1), the output is on.

The CompactBlock expansion module I/O is
exchanged with the master through a poll, changeof-state, or cyclic connection.
This module produces 1 byte for every 8 inputs.
When it is connected to a base module, an
additional byte will be returned indicating the

The CompactBlock expansion module I/O is
exchanged with the master through a poll, changeof-state, or cyclic connection.
This module produces 1 byte for every 8 inputs.
When it is connected to a base module, an
additional byte will be returned indicating the
health of the expansion module. For the Input
Status bits, when the bit is set (1), the input is on.

The module consumes 1 byte for every 8 outputs.
When an expansion module is connected, it
returns an additional byte indicating the health of
the expansion module. For the Output bits, when
the bit is set (1), the output will be turned on.
