[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).
WARNING: 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.

Preparing for an Installation Before installing the option module, do the following:
• Read the PROFIBUS Installation Guideline for details on PROFIBUS
networks.
• Verify that you have all required equipment.
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 8000-
4.5.2.
Setting the Endianness and Node Address Switches
Set the Endianness of the option module with Byte Swap switch 8 (see
Figure 1
closed ‘1’ (big-endian) data formats for the cyclic data exchanged on the
network. The cyclic data consists of the following items:
). The Byte Swap switch can be set to either open ‘0’ (little-endian) or
• CTRL: Logic Command Word (4 bytes)
• REF: Speed Reference (4 bytes)
• STAT: Logic Status Word (4 bytes)
• FEEDBACK: Speed Feedback (4 bytes)
• 0…16 Datalinks (4 bytes each)
Depending on the setting of the Byte Swap switch 8, the 4 bytes for each of the
preceding data items are swapped.

Figure 1 - Setting Option Module Node Address Switches
IMPORTANT
Each node on the PROFIBUS network must have a unique address. Set
the node address before power is applied because the option module
detects the node address during initialization (Power On Reset). To
change a node address, you must set the new value and then remove
and reapply power to (or reset) the option module.
Set the Node Address by setting Node Address switches 1...7 to their binary
equivalent, where '0' and '1' indicate switch positions 'Open' and 'Closed'
respectively. Table 1

Act], a read-only parameter, with any of the following drive configuration
tools:
• PowerFlex 20-HIM-A6 or 20-HIM-C6S HIM
• Connected Components Workbench software
IMPORTANT
Remove power from the product before installing the option module in
the 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 PowerFlex 750-Series product, 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 help 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 help 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 PowerFlex 750-Series product.
2. Remove the product 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 # 2744380), Siemens 6GK1500-0FC00, or Brad BM5G60PP4Mxxx
are recommended for use with PowerFlex 750-Series drives.

and page 67.
Chapter 2 Installing the Option Module
Configuring and Verifying Key Parameters
PowerFlex 750-Series products can be separately configured for the control
and Reference functions in various combinations. For example, you could set
the product to receive control commands from a peripheral or terminal block,
with the Reference coming from the network. You could also set the product to
receive its control from the network with the Reference coming from another
peripheral or terminal block. Or you could set the product to receive both its
control and Reference from the network.
The steps in this section assume that the product will receive the Logic
Command and Reference from the network. In this process, you will associate
the port where the PROFIBUS option module is installed with the applicable
speed reference or velocity reference parameter. In this example, the screen
captures reflect Connected Components Workbench and Port 4 is used. The
process for other configuration tools will vary. This process is not applicable to
bus supplies.
1. 753/755 - Verify that Parameter 0:301 [Access Level] is set to ‘1’ (Advanced)
or ‘2’ (Expert) to access the required parameters in this procedure.
755T - Verify that Parameter 0:30 [Access Level] is set to ‘1’ (Advanced) or
‘2’ (Expert) to access the required parameters in this procedure.
2. 753/755 - Select the Value column for Parameter 0:545 [Speed Ref A Sel],

3. 753/755: Verify that Parameter 0:930 [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
monitored by using drive Parameter 0:002 [Commanded SpdRef]. If a
problem occurs, this verification step provides the diagnostic capability
to determine whether the drive/option module or the network is the
cause.
755T: Verify that Parameter 10/11:350 [VRef 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
monitored by using Parameter 10/11:1914 [VRef Commanded]. If a
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).

20HIM-UM001
.
Setting the Node Address If the option module Node Address switches (Figure 1) are set to ‘00’
(Program), the value of Device Parameter 05 [Net Addr Cfg] determines the
node address. When the Node Address switches are in any other combination
of positions, the switches determine the node address.
1. Set the value of Device Parameter 05 [Net Addr Cfg] to a unique node
address.
2. Reset the option module; see Resetting the Option Module on page 32.
Setting a Leader-Follower Hierarchy (Optional)
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 Leader-Follower
hierarchy, the option module exchanges data with a PROFIBUS leader, such as
a ProSoft MVI56-PDPMV1 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...16
additional 32-bit parameters (Datalinks). They are configured using Host
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.
28 Rockwell Automation Publication 750COM-UM004C-EN-P - December 2020
Chapter 3 Configuring the Option Module
IMPORTANT
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, 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:
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 on page 32
3. Since the Logic Command and Reference is always used in the option
module, configure the parameters in the PowerFlex 750-Series product to
accept the Logic Command and Reference from the option module.
4. 753/755: When using the controller for speed reference via the option
module, set Parameter 0:545 [Speed Ref A Sel] to reflect the port where
the option module is installed (typically Port 4, which has a value of 874).
755T: When using the controller for velocity reference via the option
module, set Parameter 10:1800 [VRef A Sel] to reflect the port where the
option module is installed (typically Port 4, which has a value of 217).
5. 753/755: Verify that the mask parameters (for example, Parameter
0:324[Logic Mask]) are configured to receive the desired logic from the
option module. See the PowerFlex 750-Series product documentation for
details.
755T: Verify that the mask parameters (for example, Parameter 0:41
[Logic Mask]) are configured to receive the desired logic from the option
module. See the PowerFlex 750-Series product documentation for
details.
.
The option module is now ready to receive input data and transfer status data
to the PROFIBUS leader (controller). Next, configure the controller to
recognize and transmit I/O to the option module.

Chapter 3 Configuring the Option Module
Enable Datalinks To Read Data
The controller input image (drive-to-controller inputs) can have 0…16
additional 32-bit parameters (Datalinks). They are configured using Host
Parameters 17 [DL To Net 01] through 32 [DL To Net 16]. The number of
Datalinks actively used is controlled by the connection size in the controller.
See the controller example sections in Chapter 4
setting the connection size.
for more information on
IMPORTANT
When using a ControlLogix controller and the Generic Profile, configure the
Datalink parameters now as described in this section.
Host Parameters 17 [DL To Net 01] through 32 [DL To Net 16] configure which
parameters in the drive, option module, or any other connected peripheral
send the values to the network. You can use the PowerFlex 20-HIM-A6 or 20HIM-C6S HIM, or another drive configuration tool such as Connected
Components Workbench, 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 example, suppose you want to use Host Parameter 17 [DL To Net 01] to read
Parameter 2 of an optional I/O module plugged into drive Port 6. Using the
formula, the value for Host Parameter 17 [DL To Net 01] would be (10000 * 6)+
(2) = 60002.
Always use the Datalink parameters in consecutive numerical order,
starting with the first parameter. For example, use Host Parameters 17,
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.
To Net Parameter Value = (10000 * Port Number) + (Origination Parameter Number)
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 on page 32
The option module is configured to send output data to the leader (controller).
You must now configure the controller to recognize and transmit I/O to the

Setting a Fault Action By default, when communication is disrupted (for example, the network cable
is disconnected) or the leader (controller) is idle, the product 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 leader (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.
4Send 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]).
Figure 6 - Edit Fault Action HIM Screens
Changes to these parameters take effect immediately. A reset is not required.
If communication is disrupted and then is re-established, the drive will
automatically receive commands over the network again.
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.

Parameter 54 [Flt Cfg DL 16]
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 these parameters take effect immediately. A reset is not required.
Resetting the Option Module 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.
Figure 7 - 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 33
). 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).
IMPORTANT
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.

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.
1. Access the Status screen, which is displayed on HIM power-up.

About I/O Messaging 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 products.
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 product.
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 3

the network for the required I/O. This chapter discusses how to use the I/O

Chapter 4 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.
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.

the time of publication in Appendix C

Chapter 4 Using the I/O
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 32bit 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]. Table 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 to 130 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.

Using Datalinks 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 from 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.
• 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].
Rockwell Automation Publication 750COM-UM004C-EN-P - December 2020 39
Chapter 4 Using the I/O
IMPORTANT
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 the 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 leader 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

Automation does not assume responsibility or liability (to include

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.
About Acyclic Messaging 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.

PowerFlex 755T
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 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)
42 Rockwell Automation Publication 750COM-UM004C-EN-P - December 2020
Chapter 5 Acyclic Messaging
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
Examples
The following examples illustrate the use of these formulas.
Example 1: 753/755
To access Drive parameter 25 [Motor NP Volts], see Table 5 to find 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 = 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 1: 755T
To access Drive parameter 3 [DC Bus Volts], see Table 5 to find 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 (3 / 256) + 1 = 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 (3 / 256) = 3
Rockwell Automation Publication 750COM-UM004C-EN-P - December 2020 43
Chapter 5 Acyclic Messaging
Example 2: 753/755
To access Host Parameter 37 [Flt Cfg Logic] in the option module when the
module is installed in drive Port 4, see Table 5
to find the Slot Number
associated with Port 4 Host Parameters.
For Port 4 Host parameters, the base slot number is 0x3F. Therefore, the slot
number can be calculated using the general formula:
Slot Number = 0xCF + Quotient of (37 / 256) + 1 = 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
Example 2: 755T
To access Host Parameter 37 [Flt Cfg Logic] in the option module when the
module is installed in drive Port 4, see Table 5
associated with Port 4 Host Parameters.
to find the Slot Number
For Port 4 Host parameters, the base slot number is 0x21. Therefore, the slot
number can be calculated using the general formula:
Slot Number = 0x21 + Quotient of (37 / 256) + 1 = 0x22
The index number will be the remainder of the Port 4 Host parameter
numberdivided by 256, as shown using this formula:
Index Number = Remainder of (37 / 256) = 37
Example 3: 753/755
To access Host Parameter 1 [Sys Rated Amps] in the option module when the
module is installed in drive Port 10, see Table 5
associated with Port 10 Host Parameters.
For Port 10 Host parameters, the base slot number is 0xE7. Therefore, the slot
number can be calculated using the general formula:
Slot Number = 0xE7+ Quotient of (1 / 256) = 0xE8
The index number will be the remainder of the Port 4 Host parameter number
divided by 256, as shown using this formula:
to find the Slot Number
Index Number = Remainder of (37 / 256) = 1
44 Rockwell Automation Publication 750COM-UM004C-EN-P - December 2020
Chapter 5 Acyclic Messaging
Example 3: 755T
To access Host Parameter 1 [Output Frequency] in the option module when
the module is installed in drive Port 10, see Table 5
associated with Port 10 Host Parameters.
For Port 10 Host parameters, the base slot number is 0x3F. Therefore, the slot
number can be calculated using the general formula:
Slot Number = 0x3F + Quotient of (1 / 256) = 0x40
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 (1 / 256) = 1

Acyclic Messaging for DPV1 Class 1
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.
Example Messaging 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 Module). After the leader is setup, the ControlLogix tags
must be populated with the values to read the parameter as shown in Figure 8
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 leader 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
Rockwell Automation Publication 750COM-UM004C-EN-P - December 2020 45
Chapter 5 Acyclic Messaging
Next, manually enter a value of '1' into the
MVI56PDPMV1.MailboxCommand.AcyclicRead tag, to send the message.
Figure 8 - 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 9
Figure 9 - Acyclic Class 1 Read Response Data for Parameter 1 - [Output Frequency]
.
Figure 10 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.

Chapter 5 Acyclic Messaging
Figure 10 - Acyclic Class 1 Read Response Data using RSLogix Ladder Logic
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 module). After the leader is setup, the
ControlLogix tags must be populated with the correct slot and index
addressing values to write the parameter as shown in Figure 11
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 leader 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
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 11
Rockwell Automation Publication 750COM-UM004C-EN-P - December 2020 47
, indicates a value of 60.00 Hz.
Chapter 5 Acyclic Messaging
Figure 11 - Acyclic Class 1 Write for Parameter 520 - [Max Fwd Speed]
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 12

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
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.

Sets the port number and parameter number to which
the selected Datalinks should connect. Each selected
port/parameter will be written with data received from
the network. These are parameters written by the
controller (outputs from the controller).
If setting the value manually, the 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
01 of an optional encoder module plugged into drive Port
5. The value for Host Parameter 01 [DL From Net 01]
would be 50001 [(10000 * 5) +1].

Sets the port number and parameter number to which

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 into drive Port 6. The
value for Host Parameter 17 [DL To Net 01] would be
60002 [(10000 * 6) + 2].

Table 9 - Host Parameters (Continued)
ATTENTION: Risk of injury or equipment damage exists. Host
Parameter 33 - [Comm Flt Action] lets you determine the action
of the option module and connected drive if I/O communication is
disrupted. By default, this parameter faults the drive. You may
configure this parameter so that the drive continues to run,
however, precautions should be taken to verify that the setting of
this parameter does 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).
No Name & Description Details
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.

34 [Idle Flt Action]
Sets the action that the option module and drive will take if
the option module detects that the controller is in program
mode or faulted. This setting is effective only if I/O that
controls the drive is transmitted through the option module.
When the controller is put back in Run mode, the drive will
automatically receive commands over the network again.
