Safety Precautions
Please read the following safety precautions carefully.
ATTENTION: Risk of injury or death exists. The PowerFlex drive may
contain high voltages that can cause injury or death. Remove all power
from the PowerFlex drive, and then verify power has been discharged
before installing or removing the option module.
ATTENTION: Risk of injury or equipment damage exists. Only personnel
familiar with drive and power products and the associated machinery
should plan or implement the installation, startup, configuration, and
subsequent maintenance of the drive using the option module. Failure to
comply may result in injury and/or equipment damage.
ATTENTION: Risk of equipment damage exists. The option module
contains electrostatic discharge (ESD) sensitive parts that can be damaged
if you do not follow ESD control procedures. Static control precautions are
required when handling the option module. If you are unfamiliar with static
control procedures, see Guarding Against Electrostatic Damage,
publication
ATTENTION: Risk of injury or equipment damage exists. If the option
module is transmitting control I/O to the drive, the drive may fault when
you reset the option module. Determine how your drive will respond before
resetting the module.
ATTENTION: Risk of injury or equipment damage exists. Host
Parameters 33 - [Comm Flt Action], and 34 - [Idle Flt Action] let you
determine the action of the option module and connected drive if I/O
communication is disrupted, the controller is idle, or Acyclic messaging for
drive control is disrupted. By default, these parameters fault the drive. You
can set these parameters so that the drive continues to run, however,
precautions should be taken to verify that the settings of these parameters
do not create a risk of injury or equipment damage. When commissioning
the drive, verify that your system responds correctly to various situations
(for example, a disconnected cable or a controller in idle state).
8000-4.5.2.
ATTENTION: Risk of injury or equipment damage exists. When a system is
configured for the first time, there may be unintended or incorrect machine
motion. Disconnect the motor from the machine or process during initial
system testing.
ATTENTION: Risk of injury or equipment damage exists. The examples in
this publication are intended solely for purposes of example. There are
many variables and requirements with any application. Rockwell
Automation does not assume responsibility or liability (to include
intellectual property liability) for actual use of the examples shown in this
publication.

TIP
Connecting the Option Module to the Drive
Remove power from the drive before installing the option module in the
drive control pod.
1. Insert the option module into Port 4, 5, or 6 and tighten the module
mounting screws into the pod mounting bracket. To properly ground the
module to the drive, torque both mounting screws to 0.45…0.67 N•m
(4.0…6.0 lb•in).
2. When another module (I/O, encoder, communication, and so forth)
resides in the adjacent port to the left of the 20-750-PBUS option
module—and the lower mounting screw of that module is a larger T15
Torx head screw, perform addition steps 2a through 2d. If the port is
empty or the adjacent module already uses the smaller T8 Torx head
mounting screws, save this spare screw for future use.
The option module is shipped with a small bag containing a spare T8 Torx
head mounting screw and an adhesive-backed polycarbonate insulator
strip. The larger T15 Torx head mounting screw on the adjacent left
module may electrically contact the metal Profibus cable connector when
attached to the Profibus module. The polycarbonate insulator strip is
provided to prevent electrical contact between the smaller T8 Torx head
mounting screw and the Profibus cable metal connector when attached to
the Profibus module. Either of these possible electrical contact situations
may cause faulty operation. To prevent this, perform the following steps.
a. Remove the adjacent module’s lower mounting screw, the T15 Torx
head screw closest to the bottom of the pod mounting bracket.
To remove the captive T15 Torx head screw, the module must be
removed to back the screw out of the mounting clip.
b. Replace the larger T15 Torx head screw with the smaller, spare T8 Torx
head mounting screw.
c. Tighten the mounting screw to the pod mounting bracket to properly
ground the adjacent module to the drive. Torque the screw to
0.45…0.67 N•m (4.0…6.0 lb•in).
d. Attach the adhesive-backed polycarbonate strip to the metal Profibus
cable connector in a location that prevents electrical contact between
the connector and the adjacent module’s lower mounting screw when
the connector is attached to the Profibus module.

Connecting the Option Module to the Network
ATTENTION: Risk of injury or death exists. The PowerFlex drive may
contain high voltages that can cause injury or death. Remove power from
the drive, and then verify power has been discharged before connecting the
option module to the network.
1. Remove power from the drive.
2. Remove the drive cover and lift up the drive HIM bezel to its open
position to access the drive control pod.
3. Use static control precautions.
4. Route the Profibus cable through the bottom of the PowerFlex drive.
5. Connect a Profibus connector to the cable.
Profibus connectors are available from a variety of sources and in various
sizes. As such, there may be mechanical limitations that prohibit the use of
some connectors. Phoenix SUBCON-PLUS-PROFIB/AX/SC (Part #

Configuring and Verifying Key Drive Parameters
The PowerFlex 750-Series drive can be separately configured for the control and
Reference functions in various combinations. For example, you could set the drive
to receive control commands from a peripheral or terminal block, with the
Reference coming from the network. You could also set the drive to receive its
control from the network with the Reference coming from another peripheral or
terminal block. Or you could set the drive to receive both its control and
Reference from the network.
The following steps in this section assume that the drive will receive the Logic
Command and Reference from the network.
1. Verify that drive parameter 301 - [Access Level] is set to ‘1’ (Advanced) or
‘2’ (Expert) to access the required parameters in this procedure.
2. Use drive Parameter 545 - [Speed Ref A Sel] to set the drive speed
Reference source:
a. Set the Port field to ‘0’ as shown below.
b. Set the Parameter field to point to the port (slot) in which the option
module is installed (for example, Port 4 Reference).
The number ‘874’ in the Parameter field of the example dialog box
above is the parameter in the drive that points to the port.
3. Verify that drive Parameter 930 - [Speed Ref Source] is reporting that the
source of the Reference to the drive (Port 0) is the port in which the option
module is installed (for example, Port 4 Reference).
This ensures that any Reference commanded from the network can be

problem occurs, this verification step provides the diagnostic capability to
determine whether the drive/option module or the network is the cause.
4. If hard-wired discrete digital inputs are not used to control the drive, verify
that all unused digital input drive parameters are set to ‘0’ (Not Used).

2. Reset the option module; see Resetting the Option Module
Setting a Master-Slave Hierarchy (Optional)
30 Rockwell Automation Publication 750COM-UM004B-EN-P - September 2012
This procedure is only required if Datalinks are used to write or read data of the
drive or its connected peripherals. A hierarchy determines the type of device with
which the option module exchanges data. In a Master-Slave hierarchy, the option
module exchanges data with a Profibus master, such as a ProSoft MVI56PDPMV1 Profibus DP scanner. This scanner integrates, as a third party module,
in a ControlLogix controller backplane to allow Profibus DP communications.
Enable Datalinks To Write Data
The controller output image (controller outputs-to-drive) can have 0 to 16
additional 32-bit parameters (Datalinks). They are configured using Host
on page 34.
IMPORTANT
Configuring the Option Module Chapter 3
Parameters 01 - [DL From Net 01] through 16 - [DL From Net 16]. The data
type of a Datalink can be either a 32-bit REAL (floating point) or 32-bit integer.
The number of Datalinks actively used is controlled by the connection size
configured in the controller. See the controller example sections in Chapter 4
more information on setting the connection size.
Always use the Datalink parameters in consecutive numerical order,
starting with the first parameter. For example, use Host Parameters 01,
02, and 03 to configure three Datalinks to write data. Otherwise, the
network I/O connection will be larger than necessary, which needlessly
increases controller response time and memory usage.
When using a ControlLogix controller and the Generic Profile, configure the
Datalink parameters now as described in this section.
Host Parameters 01 - [DL From Net 01] through 16 - [DL From Net 16]
control which parameters in the drive, option module, or any other connected
peripheral receive the values from the network. You can use the PowerFlex 20HIM-A6 or 20-HIM-C6S HIM, or another drive configuration tool such as
Connected Components Workbench, DriveExplorer, or DriveExecutive software
to select the drive or peripheral by port number and the parameter by name. As
an alternate method, the parameter value can be set manually by number using
this formula:
for
From Net Parameter Value = (10000 * port number) + (Destination Parameter Number)
For example, suppose you want to use Host Parameter 01 - [DL From Net 01] to
write to Parameter 03 of an optional encoder module plugged into drive Port 5.
Using the formula, the value for Host Parameter 01 - [DL From Net 01] would
be (10000 * 5) + (3) = 50003.
Follow these steps to enable Datalinks to write data.
1. Set the values of only the required number of contiguous controller-todrive Datalinks needed to write data to the drive and that are to be
included in the network I/O connection.
2. Reset the option module; see Resetting the Option Module
3. Since the Logic Command and Reference is always used in the option
module, configure the parameters in the drive to accept the Logic
Command and Reference from the option module. When using the
controller for speed reference via the option module, set two fields in drive
Parameter 545 - [Speed Ref A Sel]:
a. Set the Port field for the drive (for example, 0 - PowerFlex 755).
b. Set the Parameter field to point to the drive port in which the option
module is installed (for this example, Port 4 Reference).
Also, verify that the mask parameters in the drive (for example,
Parameter 324 - [Logic Mask]) are configured to receive the desired
logic from the option module. See the drive documentation for details.

After the above steps are complete, the option module is ready to receive input
data and transfer status data to the Profibus master (controller). Next, configure
the controller to recognize and transmit I/O to the option module. See Chapter
4, Configuring the Profibus Master.
Enable Datalinks To Read Data
The controller input image (drive-to-controller inputs) can have 0 to 16
additional 32-bit parameters (Datalinks). They are configured using Host

18, 19, 20, and 21 to configure five Datalinks to read data. Otherwise, the
network I/O connection will be larger than necessary, which needlessly
increases controller response time and memory usage.
for more information on setting the

drive or peripheral by port number and the parameter by name. As an alternate
method, the parameter value can be set manually by number using this formula:

Follow these steps to enable Datalinks to read data.
1. Set the values of only the required number of contiguous drive-tocontroller Datalinks needed to read data from the drive and that are to be
included in the network I/O connection.
2. Reset the option module; see Resetting the Option Module
The option module is configured to send output data to the master (controller).
You must now configure the controller to recognize and transmit I/O to the
option module. See Chapter 4

Setting a Fault Action
By default, when communication is disrupted (for example, the network cable is
disconnected) or the master (controller) is idle, the drive responds by faulting if it
is using I/O from the network. You can configure a different response to these
events:
• Disrupted I/O communication by using Host Parameter 33 - [Comm Flt
Action].
• An idle controller by using Host Parameter 34 - [Idle Flt Action].
ATTENTION: Risk of injury or equipment damage exists. Host
Parameters 33 - [Comm Flt Action], and 34 - [Idle Flt Action] let you
determine the action of the option module and connected drive if
communication is disrupted or the master (controller) is idle. By default,
these parameters fault the drive. You may configure these parameters so
that the drive continues to run, however, precautions should be taken to
verify that the settings of these parameters do not create a risk of injury or
equipment damage. When commissioning the drive, verify that your
system responds correctly to various situations (for example, a
disconnected network cable or controller in idle state).
Changing the Fault Action
Set the values of Host Parameters 33 - [Comm Flt Action] and 34 - [Idle Flt
Action] to any of these responses.
Value Action Description
0 Fault The drive is faulted and stopped (default).
1 Stop The drive is stopped, but not faulted.
2 Zero Data The drive is sent 0 for output data. This does not command a stop.
3 Hold Last The drive continues in its present state.
4 Send Flt Cfg The drive is sent the data that you set in the fault configuration
parameters (Host Parameters 37 - [Flt Cfg Logic], 38 - [Flt Cfg Ref], and
39 - [Flt Cfg DL 01] through 54 - [Flt Cfg DL16]).

Setting the Fault Configuration Parameters
When setting Host Parameters 33 - [Comm Flt Action] and 34 - [Idle Flt
Action] to ‘Send Flt Cfg’, the values in the following parameters are sent to the
drive after a communication fault and/or idle fault occurs. You must set these
parameters to values required by your application.
Option Module Host Parameter Description
Parameter 37 - [Flt Cfg Logic] A 32-bit value sent to the drive for Logic Command.
Parameter 38 - [Flt Cfg Ref] A 32-bit REAL (floating point) value sent to the drive for
Reference.
Parameter 39 - [Flt Cfg DL 01]

Parameter 54 - [Flt Cfg DL 16]
Changes to these parameters take effect immediately. A reset is not required.
A 32-bit integer value sent to the drive for a Datalink. If the
destination of the Datalink is a REAL (floating point)
parameter, you must convert the desired value to the binary
representation of the REAL value. (An internet search of ‘hex
to float’ provides a link to a tool to do this conversion.)

Changes to switch settings and some option module parameters require you to
reset the option module before the new settings take effect. You can reset the
option module by power cycling the drive or by using Device Parameter 07 -
[Reset Module].
ATTENTION: Risk of injury or equipment damage exists. If the option
module is transmitting control I/O to the drive, the drive may fault when
you reset the option module. Determine how your drive will respond before
resetting the option module.
Set Device Parameter 07 - [Reset Module] to ‘1’ (Reset Module).
When you enter ‘1’ (Reset Module), the option module will be immediately reset.
An alternate method to reset the module is by power cycling the drive. When you
enter ‘2’ (Set Defaults), the option module will set ALL of its Device and Host
parameters to their factory default values. (This is the same as pressing the ALL
soft key when using the MEMORY folder method described in Restoring Option
Module Parameters to Factory Defaults on page 35). After performing a Set
Defaults, you must enter ‘1’ (Reset Module) or power cycle the drive so that the
new values take effect. Thereafter, this parameter will be restored to a value of ‘0’
(Ready).

When performing a Set Defaults, the drive may detect a conflict and then
not allow this function to occur. If this happens, first resolve the conflict
and then repeat Set Defaults action. Common reasons for a conflict
include the drive running or a controller in Run mode.
If your application allows, you can also reset the option module by
cycling power to the drive (resetting the drive) or by using the HIM’s
Reset Device function located in the drive’s DIAGNOSTIC folder.
Restoring Option Module Parameters to Factory Defaults
As an alternate reset method, you can restore the option module parameters using
a MEMORY folder menu item instead of using Device Parameter 07 - [Reset
Module] described in Resetting the Option Module
folder method provides two ways to restore the option module Device and Host
parameters:
• ALL—Restores ALL option module Device and Host parameters to their
factory default values.
• MOST—Restores MOST option module Device and Host parameters—
except Device Parameter 05 - [Net Addr Cfg] which is used for network
setup.
Follow these steps to restore option module Device and Host parameters to their
factory default values.

Installing GSD Files
ProSoft Configuration Builder (PCB) software uses Profibus slave definition files
(GSD files) to obtain basic configuration information about the Profibus slaves you
add to the network. The GSD configuration files identify the slave's capabilities so
that the MVI56-PDPMV1 module can correctly communicate with it.
Example: The 20-750-PBUS GSD file is named ‘20750D3B.gsd’. It is the GSD
file for the 20-750-PBUS option module in the drive and can be downloaded at

(Subscriber List) below the Bus Configuration window.
This view displays the slot number, configuration data, and starting input
and output addresses that will be assigned in the controller memory for the
MVI56-PDPMV1 Master. The Master uses this information to identify
and communicate with individual slaves on the network.
For this example, we will configure words for Ctrl/Stat & Ref/Fdbk. These
input and output 32-bit values are assigned to addresses within the
MVI56-PDPMV1 Master's internal database. For each new slave added to
the Profibus network, the PCB software automatically converts the input/
output byte addresses to input and output image addresses for the tag
database in the ControlLogix processor.
6. Likewise add as many modules as required.

About I/O Messaging
ATTENTION: Risk of injury or equipment damage exists. The examples in
this publication are intended solely for purposes of example. There are
many variables and requirements with any application. Rockwell
Automation does not assume responsibility or liability (to include
intellectual property liability) for actual use of the examples shown in this
publication.
Profibus DPV0 or I/O messaging is used to transfer the data which controls the
PowerFlex drive and its Reference. I/O messaging can also be used to transfer
data to and from Datalinks which are mapped to parameters in the PowerFlex
750-Series drives.
The option module includes the Logic Command, Logic Status, Reference, and
Feedback (all as 32-bit words) in the controller’s I/O image. This basic I/O must
always be configured by the Profibus configuration tool to the 20-750-PBUS
option module, enabling the ability to control and monitor the PowerFlex 750Series drive.
Additional I/O if needed, can be configured using up to 16 Datalinks to write
data and/or up to 16 Datalinks to read data. When using any combination of
these Datalinks, one 32-bit word for each Datalink will be added to the basic I/O
Input Size and/or Output Size.

Chapter 5 Using the I/O
Understanding the I/O Image
The terms ‘input’ and ‘output’ are defined from the controller’s point of view.
Therefore, output I/O is data that is produced by the controller and consumed by
the option module. Input I/O is status data that is produced by the option
module and consumed as input by the controller. The I/O image will vary based
on how many of the drive’s 32-bit Datalinks (Host DL From Net 01-16 and Host
DL To Net 01-16) are used.
Profibus Master Image
The I/O image can be configured based upon the number of Datalinks required
by the user. Ta b l e 3

Using Logic Command/ Status
The Logic Command is a 32-bit word of control data produced by the controller
and consumed by the option module. The Logic Status is a 32-bit word of status
data produced by the option module and consumed by the controller.
• Logic Command word is always the first 32-bit word in the output image.
• Logic Status word is always the first 32-bit word in the input image.

time of publication in Appendix
750-Series Drives.
C, Logic Command/Status Words: PowerFlex
52 Rockwell Automation Publication 750COM-UM004B-EN-P - September 2012
Using the I/O Chapter 5
Using Reference/Feedback
The Reference is a 32-bit REAL (floating point) piece of control data produced
by the controller and consumed by the option module. The Feedback is a 32-bit
REAL (floating point) piece of status data produced by the option module and
consumed by the controller.
• Reference word is always the second 32-bit word in the output image.
• Feedback word is always the second 32-bit word in the input image.
The Reference and Feedback 32-bit REAL value represents drive speed. The
scaling for the speed Reference and Feedback are dependent on drive Parameter
300 - [Speed Units]. For example, if Parameter 300 is set to Hz, a 32- bit REAL
Reference value of ‘30.0’ would equal a Reference of 30.0 Hz. If Parameter 300 is
set to RPM, a 32- bit REAL Reference value of ‘1020.5’ would equal a Reference
of 1020.5 RPM. Note that the commanded maximum speed can never exceed the
value of drive Parameter 520 - [Max Fwd Speed]. Ta b l e 4 shows example
References and their results for a PowerFlex 750-Series drive that has its:
• Parameter 300 - [Speed Units] set to Hz.
• Parameter 37 - [Maximum Freq] set to130 Hz.
• Parameter 520 - [Max Fwd Speed] set to 60 Hz.
When Parameter 300 - [Speed Units] is set to RPM, the other parameters are also
in RPM.

(1) The effects of values less than 0.0 depend on whether the PowerFlex 750 - Series drive uses a
bipolar or unipolar direction mode. See the drive documentation for details.
(2) For this example, drive parameter 300 - [Speed Units] is set to Hz.
(3) The drive runs at 60 Hz instead of 130 Hz or 65 Hz because drive Parameter 520 - [Max Fwd Speed]
sets 60 Hz as the maximum speed.
A Datalink is a mechanism used by PowerFlex drives to transfer data to and from
the controller. Datalinks allow a drive parameter value to be read or written to
without using a Profibus DPV1 Service. When enabled, each Datalink occupies
one 32-bit word in a ControlLogix controller, providing a mirror of the
PowerFlex 750-Series drive data value that the Datalinked parameter represents.
The following rules apply when using PowerFlex 750-Series drive Datalinks:

• The target of a Datalink can be any Host parameter, including those of a
peripheral. For example, drive parameter 535 - [Accel Time 1] can be the
target of any or all option modules installed in the drive.
Rockwell Automation Publication 750COM-UM004B-EN-P - September 2012 53
Chapter 5 Using the I/O
IMPORTANT
TIP
• The data passed through the Datalink mechanism is determined by the
settings of Host Parameters 01...16 - [DL From Net 01-16] and Host
Parameters 17...32 - [DL To Net 01-16].
A reset is always required after configuring Datalinks so that the
changes take effect.
• When an I/O connection that includes Datalinks is active, those Datalinks
being used are locked and cannot be changed until that I/O connection
becomes idle or inactive.
• When you use a Datalink to change a value, the value is not written to the
Nonvolatile storage (NVS) memory. The value is stored in volatile
memory and lost when the drive loses power. Thus, use Datalinks when
you need to change a value of a parameter frequently.
Datalinks for PowerFlex 750-Series drive peripherals (the embedded EtherNet/
IP adapter on only PowerFlex 755 drives and option modules such as an encoder
or a communication module) are locked when the peripheral has an I/O
connection with a controller. When a controller has an I/O connection to the
drive, the drive does not allow a reset to defaults, configuration download, or
anything else that could change the makeup of the I/O connection in a running
system. The I/O connection with the controller must first be disabled to allow
changes to the respective Datalinks.
Depending on the controller being used, the I/O connection can be disabled by
doing the following:
• Putting the controller in Program mode
• Disconnecting the drive from the network
• Placing the master in idle mode
DeviceLogix Datalinks are also locked while the DeviceLogix program is
running. The DeviceLogix program must first be disabled to allow changes to the
Datalinks. Set DeviceLogix parameter 53 - [DLX Operation] to ‘DisableLogic’
to disable the logic (the parameter value will then change to ‘LogicDisabld’).
A COP (Copy) instruction or a UDDT is needed—for REAL parameters,
speed Reference, and speed Feedback only—to copy the DINT data into
a REAL word for input data conversion. For output data conversion, a COP
(Copy) instruction or UDDT is needed—for REAL parameters, speed
Reference, and speed Feedback only—to copy the REAL data into a DINT
word. To determine whether a parameter is a 32-bit integer (DINT) or a
REAL data type, see the Data Type column in the chapter containing
parameters in the PowerFlex 750-Series AC Drives Programming Manual,
publication 750-PM001

About Acyclic Messaging
ATTENTION: Risk of equipment damage exists. If Acyclic Messages are
programmed to write parameter data to Non-Volatile Storage (NVS)
frequently, the NVS will quickly exceed its life cycle and cause the drive to
malfunction. Do not create a program that frequently uses Acyclic
Messages to write parameter data to NVS. Datalinks do not write to NVS
and should be used for frequently changed parameters.
Acyclic messaging is used to transfer data to the PowerFlex 750-Series drive
through the 20-750-PBUS option module and other connected peripherals that
do not require continuous updates. Acyclic messaging, or DPV1 messaging in the
case of the 20-750-PBUS option module, is also used to configure and monitor a
drive's parameters on a Profibus network. Drive parameters as well as peripheral
Host and Device parameters can be accessed via acyclic messaging for a PowerFlex
750-Series drive. For a full list of drive parameters, see the PowerFlex 750-Series

(1) Parameters for Profibus identification and maintenance records.
(1)
0-255
For accessing any parameter within a drive, a general mechanism is used to map
the parameter with a Profibus slot and index number.
Every drive device port has a base slot number which supports 256 indices in a
slot. These slot and index combinations are mapped to various drive and option
58 Rockwell Automation Publication 750COM-UM004B-EN-P - September 2012
Acyclic Messaging Chapter 6
module parameters through the 20-750-PBUS option module. These are the
general formulas used to determine the slot and index numbers for a specific
parameter.
Slot Number = Base Slot Number + Quotient of (parameter number / 256)
Index Number = Remainder of (parameter number / 256)
Due to Profibus standard requirements of various identification and maintenance
functions, there is an exception to the rule for assigning Host drive parameters.
When accessing drive parameters, the slot number will start at 0x01. This is the
formula used to determine the slot number for a Host drive parameter.
Slot Number = Base Slot Number + Quotient of (parameter number / 256) + 1
The following examples illustrate the use of these formulas.
Example 1: To access drive parameter 25 - [Motor NP Volts], see Ta b l e 5
the slot number associated with Port 0, which can be used to access the first 256
parameters. To access parameters 257…512, the slot number will increment by 1,
and so on.
For the drive (Port 0), the base slot number is 0x00 + 1 (per the exception).
Therefore, the slot number can be calculated using the general formula:
Slot Number = 0x00 + Quotient of (25 / 256) + 1 (for Drive Host Parameters) = 0x01
The index number will be the remainder of the drive parameter number divided
by 256, as shown using this formula:
Index Number = Remainder of (25 / 256) = 25
Example 2: To ac c es s Device Parameter 5 - [Net Addr Cfg] in the option
module when the module is installed in drive Port 4, see Ta b l e 5
Number associated with Port 4.
For Port 4 Device parameters, the base slot number is 0x50. Therefore, the slot
number can be calculated using the general formula:
Slot Number = 0x50 + Quotient of (5 / 256) = 0x50
The index number will be the remainder of the Port 4 Device parameter number
divided by 256, as shown using this formula:
Index Number = Remainder of (5 / 256) = 5
to find the Slot
to find
Example 3: To ac c es s Host Parameter 37 - [Flt Cfg Logic] in the option
module when the module is installed in drive Port 4, see Ta b l e 5
Number associated with Port 4 Host Parameters.
For Port 4 Host parameters, the base slot number is 0xD0. Therefore, the slot
number can be calculated using the general formula:
Slot Number = 0xD0 + Quotient of (37 / 256) = 0xD0
The index number will be the remainder of the Port 4 Host parameter number
divided by 256, as shown using this formula:
Index Number = Remainder of (37 / 256) = 37

Chapter 6 Acyclic Messaging
Acyclic Messaging for DPV1 Class 1
Example Messaging
The 20-750-PBUS option module provides the following Profibus DPV1 Class 1
Acyclic Services:
• READ—This service is used to read a parameter in the PowerFlex 750Series drive or the option module.
• WRITE—This service is used to modify a parameter in the PowerFlex
750-Series drive or the option module.
Examples of using Profibus DPV1 Class 1, Acyclic Messaging to read and write a
drive parameter is described in this section.
Read Example for Drive Parameter 1 - [Output Frequency]
To read the PowerFlex 750-Series drive parameter 1 - [Output Frequency] using a
Class 1 Acyclic Read Service, setup a ControlLogix controller (with a MVI56PDPMV1 Profibus Master). After the master is setup, the ControlLogix tags
must be populated with the values to read the parameter as shown in Figure 11
Drive Parameter 1 - [Output Frequency]:
• Slot Number = 0x00 + Quotient of (1 / 256) + 1= 1
• Index Number = Remainder of (1 / 256) = 1
• Length in bytes of the value of the parameter (32 bit floating point value) /
8 = 4
.
To test the Read service, you may manually enter the values as shown below into
the MVI56-PDPMV1 controller scoped tags, where a ProSoft MVI56PDPMV1 Profibus master module is installed in the backplane of the
ControlLogix controller rack.
• MVI56PDPMV1.Mailbox.AcyclicRead.Out.SlotNumber = 1
• MVI56PDPMV1.Mailbox.AcyclicRead.Out.SlaveAddress = 3
• MVI56PDPMV1.Mailbox.AcyclicRead.Out.Length = 4
• MVI56PDPMV1.Mailbox.AcyclicRead.Out.Index = 1
Next, manually enter a value of '1' into the
MVI56PDPMV1.MailboxCommand.AcyclicRead tag, to send the message.
60 Rockwell Automation Publication 750COM-UM004B-EN-P - September 2012
Acyclic Messaging Chapter 6
Figure 11 - Acyclic Class 1 Read for Parameter 1 - [Output Frequency]
When the message response successfully returns, the data for the Output
Frequency parameter will be placed in the tags
MVI56PDPMV1.Mailbox.AcyclicRead.In.Data[] byte array. In the controller
program, the return message data may be copied to a locally configured program
tag, and converted by correctly assigning the data type for the Local tag to which
the data returned from the read request matches. In this drive parameter 1 [Output Frequency] example, the local tag's data type should be a floating point
or a ‘REAL’ data type.
Acyclic Class 1 Read response data can be viewed as shown in Figure 12
Figure 12 - Acyclic Class 1 Read Response Data for Parameter 1 - [Output Frequency]
.
Figure 13 shows the RSLogix ladder logic example, that may be used to interface
the MVI56-PDPMV1 module’s functional block and perform continuous DPV1
Acyclic Read operations.

Write Example for Drive Parameter 520 - [Max Fwd Speed]
To write to the PowerFlex 750-Series drive parameter 520 - [Max Fwd Speed]
using a Class 1 Acyclic Write Service, setup a ControlLogix controller (with a
MVI56-PDPMV1 Profibus Master). After the master is setup, the ControlLogix
tags must be populated with the correct slot and index addressing values to write
the parameter as shown in Figure 14
Drive Parameter 520 - [Max Fwd Speed]:
• Slot No. = 0x00 + Quotient of (520 / 256) + 1 = 3
• Index No. = Remainder of (520 / 256) = 8
• Length in bytes of the value of the Parameter (32 bit floating point value) /
8 = 4
To test the Write Service, you may manually enter the values as shown below into
the MVI56-PDPMV1 controller scoped tags where a ProSoft MVI56-PDPMV1
Profibus master module has been installed in the backplane of the ControlLogix
controller rack.
• MVI56PDPMV1.Mailbox.AcyclicWrite.Out.SlotNumber = 3
• MVI56PDPMV1.Mailbox.AcyclicWrite.Out.SlaveAddress = 3
• MVI56PDPMV1.Mailbox.AcyclicWrite.Out.Length = 4
• MVI56PDPMV1.Mailbox.AcyclicWrite.Out.Index = 8
.
The data bytes to be written can be entered in the
MVI56PDPMV1.Mailbox.AcyclicWrite.Out.Data[] array, or the data may be
62 Rockwell Automation Publication 750COM-UM004B-EN-P - September 2012
Acyclic Messaging Chapter 6
copied via ladder logic and a locally configured program tag which represents the
correct data type, for the data value, to be written to drive parameter 520. In this
example, the value would be a floating point or ‘REAL’ data type. The value
shown in Figure 14
Figure 14 - Acyclic Class 1 Write for Parameter 520 - [Max Fwd Speed]
, indicates a value of 60.00 Hz.
To manually trigger the message to be sent, enter a value of '1' into the
MVI56PDPMV1.MailboxCommand.AcyclicWrite tag.
The message response status indicates success when the data in the
‘MVI56PDPMV1.Mailbox.AcyclicWrite.In.ErrorDecode’ tag is a value of 0x00.
Note that any non-zero value indicates an error has occurred.
Acyclic Class 1 Write response data can be viewed as shown in Figure 15

Chapter 7 Troubleshooting
Viewing and Clearing Events
The option module has an event queue to record significant events that occur in
the operation of the module. When such an event occurs, an entry consisting of
the event’s numeric code and a timestamp is put into the event queue. You can
view the event queue with any of these drive configuration tools:
• PowerFlex 20-HIM-A6 or 20-HIM-C6S HIM
• Connected Components Workbench software, version 1.02 or later
• DriveExplorer software, version 6.01 or later
• DriveExecutive software, version 5.01 or later
For details on viewing and clearing events with the HIM, see the PowerFlex 20HIM-A6/-C6S HIM (Human Interface Module) User Manual, publication
20HIM-UM001
The event queue can contain up to 32 entries, which are stored in an EEPROM
chip—making the event queue nonvolatile. Eventually the event queue will
become full, since its contents are retained through option module power cycles
and resets. At that point, a new entry replaces the oldest entry. Only an event
queue clear operation or the corruption of the EEPROM group containing the
event queue will clear the event queue contents. In the latter case, the option
module will not generate a fault to indicate that the event queue was corrupted.
Resetting the option module to defaults has no effect on the event queue, other
than to log a Code 58 ‘Module Defaulted’ event.
.
Many events in the event queue occur under normal operation. If you encounter
unexpected communications problems, the events may help you or Allen-Bradley
personnel troubleshoot the problem. The following events may appear in the
event queue.

Sets the port number and parameter number to
which the selected Datalinks should connect. Each
selected port/parameter will be read and their
values transmitted over the network to the
controller. These are parameters read by the
controller (inputs to the controller).
If setting the value manually, the parameter value
= (10000 * port number) + (origination parameter
number). For example, suppose you want to use
Host Parameter 17 - [DL To Net 01] to read
Parameter 02 of an optional I/O module plugged

33 [Comm Flt Action]
Sets the action that the option module and drive
will take if the option module detects that I/O
communication has been disrupted. This setting is
effective only if I/O that controls the drive is
transmitted through the option module. When
communication is re-established, the drive will
automatically receive commands over the network
again.

Fault Action A fault action determines how the option module and connected drive act when
a communication fault (for example, a disconnected cable) occurs or when the
controller is switched out of run mode. The former uses a communication fault
action, and the latter uses an idle fault action.
Fault Configuration When communication is disrupted (for example, a cable is disconnected), the
option module and PowerFlex drive can respond with a user-defined fault
configuration. The user sets the data that is sent to the drive using specific fault
configuration parameters in the option module. When a fault action parameter is
set to use the fault configuration data and a fault occurs, the data from these
parameters is sent as the Logic Command, Reference, and/or Datalinks.

‘output’ (From Net) are defined from the controller's point of view. Output is
produced by the controller and consumed by the option module. Input is
produced by the option module and consumed by the controller.
Logic Command/Logic Status The Logic Command is used to control the PowerFlex 750-Series drive (for
example, start, stop, and direction). It consists of one 32-bit word of output to the
option module from the network. The definitions of the bits in this word are
shown in Appendix C

The Logic Status is used to monitor the PowerFlex 750-Series drive (for example,
operating state, and motor direction). It consists of one 32-bit word of input from
the option module to the network. The definitions of the bits in this word are
shown in Appendix C
Master-Slave Hierarchy An option module configured for a master-slave hierarchy exchanges data with
the master device. Usually, a network has one master which is the master device,
and all other devices (for example, drives with installed Profibus DPV1 option
modules) are slave devices.
On a network with multiple masters (called a multi-master hierarchy), each slave
device must have one specified master.
Master A separate module (of a multi-module controller) or a built-in component (of a
single-module controller) that provides communication with option modules
connected to a network. See also Controller.

communication option module to provide a communication interface between
them and a network such as Profibus. An option module reads data on the
network and transmits it to the connected device. It also reads data in the device
and transmits it to the network.
The 20-750-PBUS Profibus DPV1 option module connects PowerFlex 750Series drives to a Profibus DPV0/DPV1 network. Option modules are
sometimes also called ‘adapters’, ‘cards’, ‘embedded communication options’, or
‘peripherals’. On PowerFlex 750-Series drives, option modules can also be I/O
modules, encoder modules, safety modules, and so forth.

Glossary
Profibus Network A Profibus network uses RS485 to connect devices such as controllers, drives,
motor starters and other equipment in automation systems. A Profibus network
can support a maximum of 126 devices. Each device is assigned a unique node
address and transmits data on the network at the same data rate. A cable is used to
connect devices on the network. It contains the bus signal. Devices can be
connected to the network in a daisy-chain connection.

They are on the option module and can be viewed when the drive is powered and
its cover is removed.
.
Stop Action When communication is disrupted (for example, a cable is disconnected), the
option module and drive can respond with a stop action. A stop action results in
the drive receiving zero as values for Logic Command, Reference, and Datalink
data. If the drive was running and using the Reference from the option module, it
will stay running but at zero Reference.
