What is DeviceLogix Functionality?

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.

For more information on configuring RSNetWorx for DeviceNet software for use with the DeviceLogix Editors, see Appendix B.

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.

Alarm

The Alarm function block initiates an alert based on the comparison between the input value and the threshold. The output of the DeviceLogix Alarm function block contains these alerts.

The details of the Alarm function block are outlined in the table.

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.

26 Publication RA-UM003B-EN-P - February 2010

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:

SP is Set Point

PV is Process Variable

E is (SP-PV) or (PV-SP)

CV is Output Control 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

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

• 1= Automatic

28 Publication RA-UM003B-EN-P - February 2010

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 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.

30 Publication RA-UM003B-EN-P - February 2010

Navigate the Function Block Editor Interface Chapter 2

CV Min (at 0%) REAL 0.0 Minimum value for the unscaled Control

Variable (CV).

This parameter cannot be configured when the DeviceLogix logic is in the Run mode.

Positive Deviation Alarm Limit

REAL 0.0 High deviation alarm from the set point.

Negative Deviation Alarm Limit

Status Parameters

Status parameters allow you to monitor the control algorithm running status, using the Alarm parameter's bit field as described here:

• Bit 0: CV is below minimum output limit (0=no; 1=yes)

• Bit 1: CV is above maximum output limit (0=no; 1=yes)

The bilinear transformation method is applied to convert the analog filter into the digital filter. The bilinear transformation is defined as follows.

To adjust the frequency shift due to the bilinear transformation, you must use the prewarping equation to calculate the prewarping analog frequency. The prewarping equation is as follows.

Then the value of w substitute for w

Then we apply the bilinear transformation.

Therefore, the corresponding difference equation is as follows.

Timer/Counter Category

The Timer/Counter category includes the following instruction types:

• Timers - The Timer controls the state of a single output based on the value of an Accumulator and a Preset. The Timer has two inputs called Input and Reset which control the counting of the Accumulator. The three timers available are:

– On-Delay Timer – Off-Delay Timer – Pulse Timer

All three timers have a selectable time base of either 1 millisecond or 10 milliseconds. The timers are non-retentive. Only the output status is available. No Timer Timing or Timer Done bits are available. The different timers are described in the next sections.

• Counters - There are two kinds of Counters:

– Up Counter – Up/Down Counter

The difference is the Up/Down Counter has two input path: one for up counting and the other for down counting. The Reset path binding is optional for Counters. You can also change element type by editing the name field.

Publication RA-UM003B-EN-P - February 2010 37

Chapter 2 Navigate the Function Block Editor Interface

On Delay Timer

The On Delay Timer delays the output response to an input by a desired amount of time. When the input is TRUE, the timer increments the accumulator and when the input goes FALSE the timer resets the accumulator. For each time base unit of time, the timer increments the accumulator. When the accumulator reaches the preset value, the timer sets the output to TRUE. The timer maintains the output TRUE status as long as the input remains TRUE.

When the input changes from TRUE to FALSE, the timer resets both the output and the accumulator. If the input goes FALSE before the time period specified by the time base and preset, the output remains FALSE and the accumulator is cleared, essentially ignoring the input.

If the device supports retentive type Timer or Ccounter, then the accumulate value of the Timer/Counter will be retained during power-down. When the power is cycled and the logic resumes running, it updates based on the previous accumulate value.

The valid data ranges are as follows.

Parameters Data Range

38 Publication RA-UM003B-EN-P - February 2010

Navigate the Function Block Editor Interface Chapter 2

Off Delay Timer

The Off-Delay Timer works the same way as the On-Delay Timer but instead of delaying the TRUE status of the output, it delays the FALSE status of the output. The input to this timer is a level sensitive FALSE with an edge-triggered reset on the FALSE to TRUE transition. This means that when the input is FALSE, the timer increments the accumulator and when the input goes TRUE the timer resets the accumulator. For each time base unit of time, the timer increments the accumulator.

When the accumulator reaches the preset value, the timer sets the output to FALSE. The timer maintains the output FALSE status as long as the input remains FALSE. When the input changes from FALSE to TRUE, the timer sets the output to TRUE and resets the accumulator. If the input goes TRUE before the time period specified by the time base and preset, the output remains TRUE, and the accumulator is cleared, essentially ignoring the input.

If the timer senses a TRUE level on the reset input at any time during the operation of the timer, it resets the output to FALSE and clears the accumulator. Because the reset line is level sensitive, the timer remains reset until the timer detects a FALSE on the reset input. Also, because the input is level sensitive, the timer again begins to increment the accumulator if the reset line goes FALSE while the input remains FALSE. However, because the reset logic already set the output to FALSE, the time delay causes no effect because the output is already FALSE. If the input is TRUE when the reset goes FALSE, the timer sets the output to TRUE.

The valid data ranges are as follows.

Parameters Data Range

PRE 0 ~ 65535 ACC 0 ~ 65535 Time Base 0 (1 ms), 1 (10 ms)

Pulse Timer

The Pulse Timer generates a TRUE value on its output for a fixed amount of time. The duration of the TRUE pulse is determined by the preset value along with the time base of the timer. When the input to the timer changes from FALSE to TRUE, it sets the output to TRUE and starts the accumulator counting. It then increments the accumulator each time the time base number of milliseconds has expired. When the accumulator reaches the preset value, the timer resets the output to FALSE.

In the Pulse Timer, the input acts only as a trigger to start the accumulator counting. Once the accumulator starts timing, it continues to rise regardless of the state of the input. As long as the output is TRUE and the accumulator is counting, additional triggers of the input do not affect the state of the output or the count of the accumulator. Once the accumulator reaches the preset value and the timer resets the output to FALSE, the Pulse Timer can again trigger the process by sensing a FALSE to TRUE transition on the input pin. Even if the input remains on the entire time the accumulator is counting, when the accumulator reaches the preset value, the timer resets the output to FALSE.

At any point during the operation of the timer, if it detects a TRUE level on the reset input, it will disable the timer and set the output to FALSE. The timer must again be triggered by a FALSE to TRUE transition on the input. This means that if the input is TRUE and the timer is reset, the timer will remain inactive. Even if the reset changes back to FALSE while the input is TRUE, the timer remains inactive. In order to start a new pulse operation, the input must change to FALSE and then back to TRUE.

Up Counter

The Up Counter has two inputs called Input and Reset and one output called Output. The Up counter simply counts up on a FALSE to TRUE transition and sets its output to TRUE when the accumulator reaches the preset value. The accumulator continues to count up until the counter is reset or it reaches 65,535. A TRUE value on the reset input zeros the accumulator and sets the output to FALSE.

An illustration of the counter function with a preset value set to 3 is below.

The valid data ranges are as follows.

Parameters Data Range

PRE 0 ~ 65535 ACC 0 ~ 65535

Up/Down Counter

The Up/Down counter has three inputs called Input, Reset, and Count Down Input and one output called Output. The counter increments the accumulator any time the Input changes from FALSE to TRUE and decrements the counter any time the Count Down Input changes from FALSE to TRUE. When the accumulator is above or equal to the preset value, the counter sets its output to TRUE. When the accumulator falls below the preset, the counter resets its output to FALSE. Like the Up Counter, the Up Down Counter resets when a TRUE level is detected on the Reset input. When a reset occurs, the counter zeros the accumulator and sets the output to FALSE.

Enable Line Feature

Enable Line can be supported by each instruction type in the Function Block Editor. When an instruction supports the Enable Line feature, that particular instruction can only be executed when the Enable Line feature is on; otherwise, that instruction maintains the data from the last data scan. Each instruction that uses Enable Line must configure both an input and an output; the output has the same real time data as the input, passing the enable information to the next instruction.

50 Publication RA-UM003B-EN-P - February 2010

Navigate the Function Block Editor Interface Chapter 2

The Enable Line feature can have two data sources:

• If an input uses Enable Line to bind with an input point or other function block’s output, the input retains this point’s data value.

• If an input uses Enable Line in an unbound capacity, the input uses the default constant value (which you can set on each instruction’s property page).

TIP

The EDS file for a device must explicitly specify support for this functionality to be available. If a device’s EDS file does not support this feature, this functionality will not be available.

Schematic View

The schematic sheet is the area in which you place function blocks to create logic. The area is laid out on a grid with letters A through L representing the columns and numbers 1 through 12 representing the rows. This area is large enough to easily place all the function blocks, I/O tags, and associated connecting wires needed to create the desired logic.

TIP

The printed schematic uses 12 size A sheets of paper. The editor prints the schematic on four rows of three sheets. The schematic is printed at full size, regardless of the setting of the current zoom level. To make adjustments to the schematic before printing, you can use the print preview feature to see how the schematic will print. The schematic can also be sent to a plotter for easier viewing.

TIP

The zoom level controls how much of the schematic you see at any given time. If you want to see more of the schematic, zoom out. If you want more detail, zoom in. You can also use the scroll bars to move the schematic sheet around to display parts of the schematic that do not fit on the display.

Because a device has limited memory to store logic, the display of uploaded information may not match the appearance of information downloaded to the device. Therefore, once your logic configuration is complete, you should print a copy of it for your records.

Chapter 3 Bind Function Blocks with I/O

Overview of Inputs and Outputs

Function blocks contain both inputs and outputs. Inputs to function blocks can be attached to any of the input types or to the output of another function block. Only one connection can be made to one function block input pin and an input cannot be tied to another input. Outputs from function blocks can be attached to either hardware or network outputs or to the inputs of other function blocks. A single function block output can be the source of (and connected to) any number of hardware outputs or function block inputs. Hardware outputs cannot be tied to other hardware outputs, and hardware inputs cannot be tied to other hardware inputs.

Inputs

Device inputs can connect to any function block input or can drive an output directly. The number and type of inputs varies from device to device. However, devices may support the following five types of inputs (supported categories based on device) and are described below.

Input Category Description

Hardware (physical) Hardware inputs represent the actual inputs (such as sensors and

switches) attached to a particular device.

Network Network inputs represent data sent from a master that can be

used in the device’s logic.

Status Status inputs indicate the state of the device. For example, if an

explicit message connection exists between the device and a master, an ’Explicit connection exists’ input would be set to true, possibly impacting the logic that the device performs.

Fault Fault inputs are conditions that report device errors. For example,

if a device detects a short circuit on an output, it can set a fault input to true. The fault input can then impact the logic that the device performs.

Note: Currently, faults can be of the Boolean type only which indicates a device fault status, while the other input types can be Boolean or Analog.

Miscellaneous Miscellaneous inputs reflect a status or a condition that is

specific to each individual product.

68 Publication RA-UM003B-EN-P - February 2010

Bind Function Blocks with I/O Chapter 3

Outputs

DeviceLogix device outputs (either Boolean or Analog) can connect to the output of any function blocks or can be driven directly by an input. There are two types of outputs described below.

Output Category Description

Hardware Hardware outputs 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 (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 Network outputs report the results of the local logic to a master.

These outputs can be attached to any output point on any function block, and are part of the produced data from the device. They can also be connected to status, faults, or inputs.

Connect I/O points and function block instructions

Once you have I/O points and function blocks represented in your workspace, you want to connect them to actually create the flow of the logic. You can:

• bind the function block’s input to input components

• bind the input component directly to output component

• bind the function block’s output to function block’s input

Connection rules

When making connections, keep the following rules in mind:

• You can attach a function block output pin to any function block input pin. This gives you feedback capability.

• You can tie a hardware input or any other input pin directly to a hardware or network output pin.

• You cannot tie hardware or network output connection pin to a function block input pin.

• You cannot attach a function block output pin to any input pin.

Publication RA-UM003B-EN-P - February 2010 69

Chapter 3 Bind Function Blocks with I/O

• A green circle indicates that the connection is valid.

• A red circle indicates that the connection is invalid.

Determine the status of a connection

Once a connection is made, you can use the Negate and Assume Data Available options to determine the state of that connection.

Negate Data

The Negate function causes the status of the data to be negated before it enters the function block. The negate operation cannot be used for analog types.

TIP

Using the Negate option does not require the use of one of the available function blocks (as would a Not function block) .

70 Publication RA-UM003B-EN-P - February 2010

Bind Function Blocks with I/O Chapter 3

Set Assume Data Available

The Assume Data Available feature should be used when feedback paths are involved in your logic; this feature assists the Function Block Editor in determining the function block process order. When feedback paths are used, the Function Block Editor’s execution order algorithm may be unable to determine which function block needs to be resolved first. In this case, you must specify which function block will be evaluated first by designating that the Function Block Editor should assume that data is available at a specific input. Once selected, a double-headed arrow appears at the end of the wire indicating that it has precedence in the logic.

TIP

Following a verify operation, the software may indicate that it could not resolve the execution order. In this case, you just use the Assume Data Available feature to resolve the conflict.

Chapter 3 Bind Function Blocks with I/O

Configure the Macro Instruction

Beginning with DeviceLogix firmware revision 4, certain devices support the Macro instruction, which defines a set of logic routines. Once defined, a Macro instruction behaves like other instructions in logic.

A Macro definition contains an instruction and may reference any output inside this logic and wiring. It does not contain any product scope I/O. The name of a Macro definition cannot duplicate any existing DeviceLogix instruction name or another existing Macro definition name.

The maximum number of Macro definitions permitted is defined in the DeviceLogix capability information, which is included in the EDS file.

Work with the Macro Instruction

You can access, edit, and manage Macro instructions through new Tools menu options:

• Create Macro Block

• Macro Block Manager

• Open Macro Block Definition

• Delete Macro Block

• Open Macro Block Logic

Using a Macro instruction encompasses these general steps, each of which is described in following sections.

1. Create the Macro definition

2. Define the external I/O binding

3. Add parameters

4. Set security (optional)

5. Apply the Macro definition

6. Add the Macro instruction to logic

7. Manage the Macro

Offline Operations

Online Operations

Once configured, products containing DeviceLogix functionality can operate without a network to perform small local control functions. Rockwell Automation advises that you use standard DeviceNet cabling in these applications to accommodate the device’s power requirements and future configuration needs.

When a network is not used, enable the Comm Status Override Parameter on the Device Parameters Tab. This will override any errors that are generated because there is no network. If this parameter is not enabled, the Outputs will not react to the local logic.

You can perform the following functions when you work on line:

• Communicate with devices

•View the status of I/O with online animation

•Change logic

• Change the value of timers and counters

• Enable and disable logic

•Verify logic

•Compare logic

• Upload and download logic

•Force

• Clear latched hardware faults

Go Online

Once you've created your logic and set up your Scanlist or Override Parameters, you are ready to go online. While the system is online, you can make changes (for example, to the Timer and Counter

values) and to the program itself.

Perform the following steps to go online in RSNetWorx software:

1. Click the Online icon on the RSNetWorx software toolbar.

2. Once the network browse is completed, double-click the device

that you want to connect to. The Device Properties dialog is displayed.

3. Click the DeviceLogix tab.

You may be asked to Upload or Download if you haven't already done so. Click OK.

4. Once the upload or download is completed, click the Start Logic Editor button.

You se e:

• The local logic resident in the device

• The real-time status of the inputs and outputs indicated by data on the connecting wires.

• Logic Enabled or Logic Disabled displayed in the online toolbar, depending on the state of the device. You can change the state by simply selecting the desired state.

• The word Animated displayed in the status bar, which indicates that the logic on the screen matches the logic in the device. If you do not see Animated and you want the logic on the screen to match the logic in the device, you must perform an upload or download to synchronize the logic.

5. Double-click on an element. Then select the Parameter tab to

view the updating parameter values.

Change Function Block Attribute Values

Many function blocks have attributes that can be modified online. For example you can change Timer block’s Preset (PRE) and Accumulator (ACC) while the logic is running. See the following figure.

Change Logic

While the Function Block Editor is running and animated, you can change the logic that appears on the schematic by first pressing the Edit button or selecting Tools > Edit. When you change the logic, the Function Block Editor will change from the Animated mode into Pending Edits mode. The logic in the device will not be affected and the current program will continue to run. However, the screen will not reflect the real-time status of the logic. The data on the wires will be frozen to whatever it was when you modified the logic. To ensure your changes take affect, perform the following steps:

1. Select Tools > Edit so that a check mark appears on the menu,

indicating that you are in Edit mode.

2. Select Communications > Download.

You see a message that tells you that logic is running and asks you if you would like to stop it. If you:

•Select No - the logic is not downloaded to the device and the current logic continues to run in the device.

•Select Yes - the logic does not continue to run in the device and new logic is downloaded to the device. When the download is complete, you are asked if you want to start the logic running again. If you:

– Select No - the online toolbar displays Logic Enable Off. – Select Yes - the online toolbar displays Logic Enabled On; the

Function Block Editor is animated. The message Not Saved displays in the status bar until you exit the Function Block Editor and save the new configuration in RSNetWorx for DeviceNet software.

TIP

Note that you can use the edit mode icon on the standard toolbar to enter edit mode.

You can use the download icon on the online toolbar to download logic to the device.

Enable and Disable Logic

Logic Enable On

Use the Logic Enable On function to notify the device to start processing the stored logic diagram. To set Logic Enable On, select Communications > Logic Enable On.

Logic Enable Off

Use the Logic Enable Off option to notify the device to stop executing the logic diagram. When you select this option, the device enters an idle state, turning off the Logic Enable Bit in the produced data. The Logic Enable bit in the Produced I/O assembly of the device reflects a 0 or 1 for Logic Enable Off or Logic Enable On. To set Logic Enable Off, select Communications > Logic Enable Off.

Verify Logic

To verify the logic’s syntax, click the Verify icon in the standard toolbar or Tools > Verify. The verify results will be displayed in the message log window. If an error is identified, double-click the error message to have the current caret jump to the error block.

TIP

You can only download the logic to the device after verifying and passing the verification without an error.

For devices running firmware revision 3, each instruction’s instance ID number is assigned and valid only after verification. This number may change if the placement of the instruction changed.

For devices running firmware revision 4 or higher, each instruction’s instance ID number is assigned once and will never change.

Upload and Download Logic

Upload Logic

To upload logic, select Communications > Upload. The logic configuration in the device is read and displayed in the Function Block Editor. Any unsaved changes will be discarded and Online Animation begins.

Note that some devices are capable of storing screen format information. If a particular DeviceLogix-enabled device supports this feature (dependent on the static memory size), the function block logic and layout position information is stored and will be returned with an upload. Further, the text comments are also saved, but the quality of the content cannot be guaranteed.

When you upload, the uploaded information is not automatically stored into the RSNetWorx for DeviceNet software .dnt file. You must make sure you save any changes after you exit the DeviceLogix Editor to ensure that any changes made to the schematic are saved, including changes made as a result of an upload.

Download Logic

To download logic, select Communications > Download. The logic configuration in the Function Block Editor is duplicated and transferred to the device. Before a download can be performed, the logic must pass the verification process. See Verify Logic for more information.

Publication RA-UM003B-EN-P - February 2010 89

Chapter 3 Bind Function Blocks with I/O

You can download when logic is enabled or disabled. If you download logic when logic is enabled, the download process occurs as follows:

• The Function Block Editor checks to see if logic is enabled in the device.

• If the logic is enabled, you are asked if you want to disable logic. If you:

– Select No - the logic is not downloaded to the device and an

error message displays.

– Select Yes - the logic is downloaded to the device.

• If logic was enabled before you downloaded, when the download is complete, you are asked if you want to re-enable the logic. If for some reason the screen format cannot be downloaded into the product, an error message will be displayed and the screen format will not be saved. If logic was not enabled before you downloaded, you are not prompted to enable or disable the logic.

• When the download is complete, you are notified that the download was successful. Note that if the master is currently scanning the device to which you are downloading, you must first access the DeviceNet scanner's scanlist to remove the device from the scanlist. If this new logic results in different connection sizes, you must adjust the master as follows:

– Put the master in Idle mode (This may mean turning a

processor's key switch to Program.)

– Access the device parameter’s to change the size of the

connections.

– Download the device to the scanlist. – Click the Edit I/O Parameters button and verify the Rx and Tx

size corresponds to the new connection size.

– Put the master in Run mode for normal operation.

You can click the Cancel button anytime during the download process to abort downloading the logic to the device. If you click the Cancel button, an error message displays and neither old logic nor new logic exists in the device. You must let the download complete for logic to be contained in the device.

If logic is enabled during the download process, once the download is complete, online animation starts. You see the real time values on the wires connecting the elements. If logic is disabled, there is not any activity; the current state of connections is displayed and inputs can be changed, but online animation does not start.

Bind Function Blocks with I/O Chapter 3

When you download, the downloaded information is not automatically stored into the RSNetWorx for DeviceNet software .dnt file. You must make sure you save any changes after you exit the DeviceLogix Editor to ensure that any changes made to the schematic are saved, including changes made as a result of an upload.

Forcing

The DeviceLogix Function Block Editor provides troubleshooting capabilities by allowing you to force inputs and outputs that allow you to verify the run time result of your logic.

To aid in troubleshooting and debugging of your schematic, you can force hardware inputs and hardware outputs. No other inputs or outputs can be forced within the Function Block Editor. Network inputs can be forced in the device from where they originate. If you exit the Function Block Editor with a force enabled, that force will stay in effect until you remove it.

To apply forces, right-click on the input or output element you wish to force. A pop-up appears that lists the forcing options .

TIP

You cannot use the Force function in offline mode.

If Logic Enable is Off (logic is not running in the product), the Force function has no effect. In this case, if the Force value is modified, it will not take effect until Logic Enable is On.

TIP

You do not have to be in Edit mode to use forces.
