What is DeviceLogix Functionality?
1
Introduction
DeviceLogix functionality has been added to a number of Rockwell
Automation devices to control outputs and manage status information
locally within the device.
The configuration of the DeviceLogix functionality is accomplished
through the DeviceLogix Editor. The DeviceLogix Editor includes two
kinds of logic configuration tools for DeviceLogix devices to meet
different configuration preferences:
• Function Block Editor - provides a graphical interface for
configuring function blocks to provide local control within
DeviceLogix-capable devices.
• Ladder Editor - provides a ladder-style configuration tool for
DeviceLogix-capable devices. Beginning with firmware
revision 4, two Ladder Editors are available within DeviceLogix.
The Old Ladder Editor supports DeviceLogix, firmware
revision 3 and earlier. The New Ladder Editor supports
DeviceLogix, firmware revision 4.
The DeviceLogix Editor is an applet of RSNetWorx for DeviceNet
software and Drive Tools software, and it can be launched directly
from those hosts.
With DeviceLogix-capable devices, you can enable a logic operation
using the DeviceLogix Editor to provide local control over the device’s
operation. A DeviceLogix device consists of:
• a specific number of inputs and/or outputs.
• local logic that determines its behavior.
11Publication RA-UM003B-EN-P - February 2010 11
Chapter 1 What is DeviceLogix Functionality?
Inputs and Outputs
Inputs and outputs can be one of two types.
• Physical - Inputs and outputs realized by physical connections to
the device. These are referred to as Discrete/Analog Inputs or
Discrete/Analog Outputs.
• Networked - Inputs consumed by the device from the network
and outputs produced by the device onto the network.
Input and Output Bits
There are five types of DeviceLogix inputs. Inputs are read from the
Electronic Data Sheet (EDS) file or are created dynamically during
logic configuration. The inputs that are read from the EDS file cannot
be modified. The DeviceLogix inputs are:
•Device Input - A physical input of the device. Device inputs
represent the actual inputs, such as sensors and switches,
attached to a particular device.
• Network Input - Formerly called the Consumed Network Bit
(CNB), network input is data sent from a master that can be
used in the device’s logic.
• Device Status - Status inputs indicate the state of the device. For
example, if an explicit message connection exists between the
device and a master, an input called ‘explicit connection exists’
is set to true and possibly affects the logic the device performs.
• Device Fault - Faults are conditions that report device errors. For
example, if a device detects a short circuit on an output, a fault
input is set to true and possibly affects the logic the device
performs.
12 Publication RA-UM003B-EN-P - February 2010
What is DeviceLogix Functionality? Chapter 1
There are two types of DeviceLogix outputs:
• Device Output - Hardware outputs that are the actual outputs,
such as lights and actuators, attached to a particular device.
Without DeviceLogix functionality, the master would normally
control the outputs via consumed data. In fact, if there is no
local logic controlling an output, the master controls the output
as it would if DeviceLogix functionality were not running on the
device. However, within DeviceLogix functionality, if the local
logic controls an output, the master no longer controls the
output. The only way the master can affect the state of an output
that is under local control is to route requests to the local logic
by using network inputs. Some outputs can be under local
control while others can still be controlled by the master.
• Network Output - Formerly called Produced Network Bit (PNB),
Network outputs report the results of the local logic to a master
and are part of the produced data from the device.
Local Function Block Logic
The local logic of a DeviceLogix device consists of function blocks,
inputs, outputs, and connections (wires) between them. Function
blocks contain connection points (called pins) and perform a specific
function. Inputs and outputs also have connection pins and represent
the actual hardware devices, networked data, and fault and status bits
that are available for use in the local logic.
A connection (wire) between function blocks is defined when an
input pin of one function block is bound to an output pin of another
function block. A pin can be bound to a:
• pin of another function block.
• physical input/output.
•networked input/output.
• fault or status bit.
• miscellaneous bit.
• block input enable bit and block output enable bit.
Function blocks may also have attributes that influence their function.
Configuring a DeviceLogix device consists of defining or editing the
local logic that is present on the device along with the EDS parameters
for that device.
Publication RA-UM003B-EN-P - February 2010 13
Chapter 1 What is DeviceLogix Functionality?
Local Ladder Logic
The local logic of a DeviceLogix device consists of rung, branch,
contact, output coil, and box instructions. A box instruction performs
a specific function (such as Timer or Counter). Contact and coil
instructions could be hardware data, networked data, and fault and
status bits that are available for use in the local logic. Additionally,
contact could also refer the output of a box instruction.
The DeviceLogix Editor is a graphical tool for building DeviceLogix
functionality in DeviceLogix-enabled products. With the editor, you
can create logic, bind logic input and output, verify logic,
upload/download logic and enable/disable logic in
DeviceLogix-enabled products. When logic is running (in online mode
and when logic is enabled), real-time data is animated in the editor
and you can also implement forces or perform online parameter
modification for some function types.
DeviceLogix Functionality and Associated Host Software
You configure DeviceLogix features through RSNetWorx for DeviceNet
software and Drives Tools software. The DeviceLogix Editor ships as
part of RSNetWorx for DeviceNet software, starting with revision 3.0.
EDS files that enable DeviceLogix functionality are also shipped with
RSNetWorx for DeviceNet software in a separate folder labeled
Additional EDS Files.
For more information on registering EDS files, see Appendix A.

Chapter 1 What is DeviceLogix Functionality?
Launch the DeviceLogix Editor
After you configure the properties for your DeviceLogix-enabled
device (for more information, see Appendix A), you can launch the
DeviceLogix Editor. You see an additional tab in the device properties
dialog box for all DeviceLogix-enabled devices. This tab is labeled
DeviceLogix. This tab provides access to the start-up window for the
DeviceLogix Editor. You have the option to fill in your name, a
revision number, and a description of your configuration (all optional
fields)..
IMPORTANT
16 Publication RA-UM003B-EN-P - February 2010
If you are on line and you click on either the Parameters or the
DeviceLogix tab, you may be prompted to upload or download
the device. When you are on line, the dialog checks the
configuration in the device and compares it to the current
configuration. If the configurations are not the same, you must
upload from or download to the device to make the
configurations the same before you can make changes. If you
need to make changes without uploading or downloading, you
can exit the dialog box, go off line and re-enter the dialog box
to make the desired changes.
What is DeviceLogix Functionality? Chapter 1
To start the DeviceLogix Editor for a DeviceLogix-enabled device,
click Start Logic Editor. On the DeviceLogix Editor Style Selection
dialog, you are prompted to select the editor type that you want to
launch. After selecting an editor type, click OK.
If the current device does not support one of the editor types, that
editor type will be grayed out.
IMPORTANT
If you select an editor type for a particular device and that type
is committed to the .dnt file (clicking OK or Apply), that editor
style is registered. Therefore, you cannot switch to another
editor style in that same .dnt file (the next time you launch the
DeviceLogix Editor Style Selection dialog, the other editor style
is grayed out). If you want to change the editor type (and a
device supports both editor types), you must create a new
project file, add this device again, and then select the other
editor type.

Function Block Instructions
The DeviceLogix Function Block Editor has several categories of
function block types:
•Process
•Filter
• Select/Limit
•Statistical
• Timer/Counter
•Compare
•Compute/Math
•Move/Logical
•Macro Block
Each function block type has the following tabs on its property pages:
• General tab - displays general information about this function
block instruction. You can also select the function data type (if
available) and input a comment for this block. Once any
changes have been applied, a sequence number is allocated for
this block.
• Parameter tab - Lists all of the parameters available for this
function block type. Preset data can be entered in all editable
fields. Once logic runs, the real-time value will be updated in
the Value column. Note the read-only data is grayed out and
cannot be edited.
Process Category
The Process category includes the following instruction types:
•Alarm
• Timing Diagnosis
•PID

IMPORTANT
When data values are large, switching between REAL and DINT
data types may cause a minimal loss of accuracy. For example,
a value of 99999999 DINT will be rounded up to 100000000
REAL when you switch to a REAL data type and then back to a
DINT data type.
Timing Diagnosis
The DeviceLogix Timing Diagnosis function block object determines
whether the occurrence of the expected event is within the preset
timing interval.
The following is an operation example:
The rising edge of the Trig Start input indicates the occurrence of a
Trig Start event. The rising edge of the Trig Finish input indicates the
occurrence of a Trig Finish event.
When the Trig Start event occurs, the Timing Diagnosis function block
is started. The internal timer starts timing from 0 as shown below.
Meanwhile, the function block reports the triggered status as the
output.
The events that occur in the illustration are as follows.
• If the Trig Finish event occurs before the Minimum Time, that is,
at the time slot (1), then the function block returns an early
finish status. If the occurrence of the Trig Finish event is within
the range of Min time and Min time + Range time, as shown in
time slot (2), then the Trig Finish event happens within the
expected timing slot. Therefore, a normal finish status is
returned. If no Trig Finish event occurs at the interval 0 and Min
time + Range time, then the Late Finish status is returned, as
shown in the time slot (4).
• Within the time interval 0 and Min time + Range time, if the Trig
Start event occurs again, that is as shown in the time slot (3),
then the Retrigger status is reported as the function block
output.

PID
• Once the Trig Finish event occurs, or if a Retrigger event is
detected, or the Late Finish status is reported, the function block
stops operation, and the internal timer stops timing. The
function requires a reset event to perform another operation.
• In all cases, the Reset signal overrides all other function block
functionality. If the Reset Binding attribute is not supported or it
is not bound, the function block behaves as if it is tied low.
• All input edges that occur during reset are ignored.
• The Elapsed Time attribute should be clear at the time that the
Trig Start event triggers the function block.
Use the PID function block to control a closed single analog loop.
The PID function block operates only in the timed mode. In this
mode, the function block is calculated and updates its output
periodically at a user-selectable rate. PID closed loop control holds a
process variable at a desired set point. A flow rate/fluid level example
is shown in the following figure.
Σ

Navigate the Function Block Editor Interface Chapter 2
The PID equation controls the process by sending an output to the
actuator device. The greater the error between the setpoint and
process variable input, the greater the output will be. An additional
value (feedforward or bias) can be added to the control output as an
offset. The PID result (control variable) drives the process variable
toward the setpoint.
The PID function block monitors and controls the process loop for
analog process parameters such as pressure, temperature, flow rate,
and fluid level. Features of the PID function block include:
• PID equations expressed in Dependent Gains (ISA standard)
• Input scaling in engineering units
• Zero-crossing deadband
• Derivative term acts on PV
• Direct or reverse acting control
•Output alarms
• Output limiting with anti-reset windup
• Manual mode (with bumpless transfer)
• Feedforward or output biasing
The PID function block uses the following equation with dependent
gains:

c
T

i
T

d
SP is Set Point
PV is Process Variable

The PID function has Enable In and Process Variable as inputs, and
Enable Out and Control Variable as outputs, as described in the
following tables.
Input Type Default Description
Enable In BOOL 1 Enable In
PV REAL 0.0 Process Variable
Output Type Default Description
Enable Out BOOL 0 Enable Out
CV REAL 0.0 Control Variable
The PID function also provides four parameters that you can modify
as needed:
• Tuning
•Configuration
•Scaling
•Status
Tuning Parameters
Tuning Parameters allow you to set the PID algorithm parameters.
Parameter Type Range Default Description
Setpoint (SP) REAL 0.0 Desired control point of the process variable. It
should be scaled in the engineering unit.
Set Output % REAL 0.0 ~ 100.0 0.0 PID output for the manual set output mode. Use
this value to prevent bumps in control when
switching control mode back to automatic.

Navigate the Function Block Editor Interface Chapter 2
Manual and Automatic Modes
The PID function block automatically provides bumpless
transfer from manual mode to auto mode. The PID function
block back-calculates the value of the integral accumulation
term required to make the CV output track the set output value
in manual mode. In this manner, when the loop switches to auto
mode, the CV output starts off from the set output value and no
"bump" in output value occurs.
Configuration Parameters
Configuration parameters allow you to set control loop features.
Parameter Type Range Default Description
Control Action BOOL 0 Indicates the direction of control:
• 0 is E=SP-PV
• 1 is E=PV-SP
This parameter cannot be configured when the
DeviceLogix logic is in the Run mode.
Loop Update Time UDINT 0 Periodical time interval in microseconds for
output update.
This parameter cannot be configured when the
DeviceLogix logic is in the Run mode.
CV High Limit % REAL 0.0 ~ 100.0 0.0 System's maximum allowable value for the
Control Variable. The PID function block does
not output a CV that exceeds the High Limit.
CV Low Limit % REAL 0.0 ~ 100.0 0.0 Sytem's minimum allowable value for the
Control Variable. The PID function block does
not output a CV less than the Low Limit.
Deadband Value REAL 0.0 Error range above and below the setpoint. Enter
"0" to inhibit the deadband. The deadband has
the same scaled units as the setpoint.
Deadband
The adjustable deadband is used to select an error range above
and below the setpoint where output does not change as long as
the error remains within this range. This deadband controls how
closely the process variable matches the set point without
changing the output.
Publication RA-UM003B-EN-P - February 2010 29
Chapter 2 Navigate the Function Block Editor Interface
Zero-crossing is deadband control that lets the function block
use the error for computational purposes as the process variable
crosses into the deadband until the process variable crosses the
setpoint. Once the process variable crosses the setpoint (error
crosses zero and changes sign), and as long as the process
variable remains in the deadband, the function block considers
the error value to be zero. The deadband has the same scaled
units as the setpoint.
Output Limit
An output limit (percent of output) can be set on the control
output. When the function block detects that the output has
reached a limit, the PID function block automatically avoids
reset windup by preventing the integral term from accumulating
whenever the CV output reaches its maximum or minimum
values. The accumulated integral term remains frozen until the
CV output drops below its maximum limit or rises above its
minimum limit. Normal integral accumulation automatically
resumes.
Scaling Parameters
Scaling parameters allow you to set the output scale.
Parameter Type Default Description
PV Max REAL 0.0 Maximum value for the unscaled Process
Variable (PV).
This parameter cannot be configured when the
DeviceLogix logic is in the Run mode.
PV Min REAL 0.0 Minimum value for the unscaled Process
Variable (PV).
This parameter cannot be configured when the
DeviceLogix logic is in the Run mode.
EU Max REAL 0.0 Maximum engineering unit for the Process
Variable (PV).
This parameter cannot be configured when the
DeviceLogix logic is in the Run mode.
EU Min REAL 0.0 Minimum engineering unit for the Process
Variable (PV).
This parameter cannot be configured when the
DeviceLogix logic is in the Run mode.
CV Max (at 100%) REAL 0.0 Maximum value for the unscaled Control
Variable (CV).
This parameter cannot be configured when the
DeviceLogix logic is in the Run mode.
