About This Chapter
About the Modules
This chapter introduces POINT I/O and ArmorPOINT I/O configurable
modules with DeviceLogix capability.
•About the Modules
• Quick Start - Prepare the Modules to work on DeviceNet
• Quick Start - Prepare the Modules to work on EtherNet/IP and
ControlNet
The POINT I/O and ArmorPOINT I/O modules work with EtherNet/IP,
DeviceNet, and ControlNet network adapters. Each module has eight 24V DC
I/O points that self-configure to be inputs or outputs. Inputs are IEC Type 3
and outputs are self-protecting 0.5 A outputs.
The firmware in these modules uses Version 3 (1738-8CFGDLXM8,
1738-8CFGDLXM12, 1738-8CFGDLXM23) and Version 7
(1734-8CFGDLX) of the DeviceLogix master library. The modules can
execute 144 DeviceLogix function blocks in 3 ms. Smaller programs that
contain fewer than 40 function blocks can be executed in 1 ms.
Each module produces 20 bytes of data including I/O state (8 bits), eight
user-defined bits, and eight user-defined words of analog data to be consumed
by processors or other DeviceLogix modules. Each module consumes 20 bytes
of data to set the I/O state (8 bits), eight user-defined control bits, and eight
user-defined words of analog data. It is also possible to consume the data from
up to eight other peers.
This table lists 1734 and 1738 configurable I/O modules with DeviceLogix.

Introduction
1734-8CFGDLX
This module is an 8-point 24V DC I/O module with eight self-configuring
points and DeviceLogix capabilities. Each of the I/O points can be either a
DC input or output. The module supports removal and insertion under power,
auto-address, and auto-baud in compliance with the POINTBus™ backplane.
1738-8CFGDLXM8, 1738-8CFGDLXM12, and 1738-8CFGDLXM23
The ArmorPOINT I/O family consists of modular I/O modules. The sealed
IP67 housing of these modules requires no enclosure. Environmental
requirements other than IP67 may require an additional appropriate housing.
I/O connectors are sealed M8 (Pico™), M12 (micro) or M23 styles. The
mounting base ships with the module.
Modes of Usage
The module can be used in one of the following modes:
• as a standard POINT I/O module,
• in a standalone DeviceLogix program where it controls its own I/O, and
• in network applications with or without the peer exchange of data.
Standard POINT I/O Module
The module can simply be used as an 8-point configurable POINT I/O
module. It uses ODVA pre-defined Produce and Consume assemblies. Default
settings help to facilitate quick setup right out-of-the-box. It is CIP network
independent and it can run on DeviceNet, EtherNet/IP or ControlNet when
used in conjunction with an adapter.
14 Rockwell Automation Publication 1734-UM015B-EN-E - May 2020
Introduction
Stand Alone DeviceLogix
If DeviceLogix is enabled (programmed), then the module becomes the owner
of its outputs. The DeviceLogix program reads inputs and controls the
onboard outputs.
• The produced assembly may be shared with a controller if a connection
exists.
• As the owner of its local outputs, the module may run without an
external controller.
An external controller, which is the owner of the connection to the module,
can influence the module’s logic via a consume assembly – both digital and
analog data. Configuration of the module is performed via RSNetWorx for
DeviceNet. When used on ControlNet or EtherNet/IP, the tool bridges
through the adapter to directly communicate with the DeviceLogix module on
the POINT I/O backplane.
Peer Enabled POINT I/O
The POINT I/O DeviceLogix module can “listen in” on data connections to
other POINT I/O modules on the backplane. This data can be used in the
DeviceLogix program to control the outputs. It can consume data from eight
different peers. The data from each peer can be up to 24 bytes long. The data
can be digital, analog (16-bit), or a mixture. The module supports the “Auto
Produce” parameter to produce I/O data automatically without the need for a
master. It will also produce and consume network data. Configuration of peer
data is performed via RSNetWorx.
See Chapter 6, Configuring POINT I/O and ArmorPOINT I/O DeviceLogix
modules using RSNetWorx for DeviceNet.

Parameters on the Configuration tab
Parameter Description
Off-to-On Delay This is the OFF to ON filter constant for all inputs on the module. A
high signal must be present for this amount of time before the module
will report an ON.
The value must be entered in microseconds (s). The default value is
1000 s. The minimum value is 0 and the maximum is 65535 s.
The actual resolution of this value is milliseconds. The user selected
value will be truncated at milliseconds. For example, 65535 s
represents a 65 ms filter value.
On-to-Off Delay This is the ON to OFF filter constant for all inputs on the module. A
low signal must be present for this amount of time before the module
will report an OFF.
The value must be entered in microseconds (s). the default value is
1000 s. The minimum value is 0 and the maximum is 65535 s.
The actual resolution of this value is millisecond. User selected value
will be truncated at milliseconds. For example, 65535 s represents a
65 ms filter value.
Output Fault
State
This parameter controls the action of each output during a
communication fault.
0 = Go to Output Fault Value (default)
1 = Hold Last State
This parameter is ignored if DLX Fault Override is enabled.
Output Fault
Value
The state of each output if a communication fault occurs. This
parameter is ignored if the Output Fault State is set to Hold Last State
or if DLX Fault Override is enabled.
0 = OFF (default)
1 = ON
Output Idle State This parameter controls the action of each output when in Idle state
or Program mode.
0 = Go to Output Idle Value (default)
1 = Hold Last State
This parameter is ignored if DLX Fault Override is enabled.
Output Idle Value The state of each output when in Idle state or Program mode. This
parameter is ignored if the Output Idle State is set to Hold Last State
or if DLX Fault Override is enabled.
0 = OFF (default)
1 = ON
Auto Produce Enabling this parameter will allow the module to produce data
without a master. This parameter is disabled by default.
If enabled, the module will begin to produce data on the backplane or
network after power up and network address verification (Dup MAC
check). The Owned bit in the produced assembly will be cleared (0).
A master may still make a connection to the module and then the
Owned bit will be set (1). If a master connection fails, the module will
continue to produce data, but the Owned bit will be cleared (0).
The produced assembly, EPR, and PIT are described later in this table.
Auto Production may be important to support data to listening peers.

Configuring POINT I/O and ArmorPOINT I/O DeviceLogix modules using RSNetWorx for DeviceNet
Parameters on the Configuration tab (Continued)
Parameter Description
DLX Dependent
Mode
This parameter allows the logic in the module to be enabled or
disabled according to the I/O connection status or the state of the
owning processor. The default is disabled.
If Dependent Mode is enabled, the DeviceLogix program will be
disabled when the owning processor is in program mode. When the
processor transitions to RUN, the logic will automatically be enabled.
DLX Fault
Override
When an output is being locally controlled, its state is either
controlled by the DeviceLogix program or by the Fault/Idle states.
Enabling this parameter allows the local logic to override the
Fault/Idle states in the event of a communication fault or transition to
Idle (Program) state. When this parameter is disabled (default) and a
communication fault occurs or when in Idle (Program) state, all
outputs, including those that are locally controlled, will go to the
Fault/Idle states. Enabling this parameter and using the "Network
Fault" status bit (Bus-off or Dup Mac Error) or COS/Cyclic Cnxn
Idle/Fault bits in the DeviceLogix program, a controlled stop or
maintenance of a machine state can be achieved when
communication is lost with a master.
Auto Produce
Assembly
When the Auto produce parameter is enabled, this parameter selects
which assembly to produce:
000: 20-byte assembly (default)
004: 1-byte assembly
101: 20-byte assembly
111: 8-byte assembly
For details on the contents of the assembly, see I/O Data Assembly
Maps in Chapter 4.
For the list of I/O tags, see I/O Tags
in Chapter 5.
The 20-byte assembly contains all the data. The 8-byte assembly can
be produced in one packet (non-fragmented).
Auto Produce EPR When the Auto Produce parameter is enabled, this parameter sets the
Expected Packet Rate. The units are milliseconds (ms). The default is
1000 ms. The maximum is 65535 ms and the minimum is 0 ms.
When Auto Produce is enabled, the module produces data at every
change of state (COS) or when the EPR timer expires.
Auto Produce PIT When the Auto Produce parameter is enabled, this parameter sets the
Product Inhibit Time. The units are milliseconds (ms). The default is
1 ms. The maximum is 65535 ms, and the minimum is 0 ms.
If a Change of State occurs and the PIT has not expired, the message
will wait until the PIT has expired. This can be used to prevent one
module from using all the available network bandwidth.

Configuring POINT I/O and ArmorPOINT I/O DeviceLogix modules using RSNetWorx for DeviceNet
Parameters on the Configuration tab (Continued)
Parameter Description
Peer #xx MacID There are eight (0…7) peer Mac ID parameters. Each one defines the
MacID or Slot Number of the peer from which this module will
consume data. The default is "No Connection."
You can enter the MacID or Slot number, 0…63, or a relative offset
from the address of the module (-4 to +4).
Once a valid MacID is set, Peer Exists = 1 in DeviceLogix program.
See more details on peer configuration later in this chapter and in
Appendix A
.
Peer #xx Size There are eight (0…7) Peer Size parameters. Each one defines the
size in bytes of the message received from the peer. The default and
maximum value is 24 bytes. The minimum is 1 byte. See Appendix A
for peer message sizes of POINT I/O and ArmorPOINT I/O modules.
If the received message size does not match the Peer Size value, the
data will be considered invalid and the appropriate error bits will be
set (Produced assembly: Peer Missing = 1. In DeviceLogix program:
Peer Data valid = 0.)
This parameter is ignored if the Peer MacID is set to "No Connection."
Peer #xx EPR There are eight (0…7) Peer EPR parameters. Each one defines the
Expected Packet Rate in milliseconds (ms) of the peer connection. If
this module does not receive valid data from a peer for 4 times the

This parameter should only be used in a DeviceNet system. It is used
to set another POINT I/O or ArmorPOINT I/O module to the right of
this module to Autobaud (enable) or used to save the baud rate
(disable).
This section will describe how to configure the POINT I/O and
ArmorPOINT I/O DeviceLogix module to consume data from peers. The
POINT I/O DeviceLogix module can use data from other modules to affect
the DeviceLogix program.
The module can perform the following functions:
• Get Change-Of-State (COS) data from up to eight I/O modules or
peers.
• Each peer can have up to 24 bytes of data.
• Each peer has its own expected packet rate.
• Each peer has its own status bit that can be used in logic.
• The data from each peer can be digital (bit), analog (16-bit words), or a
mixture of both.
The following functions are not supported:
• Make a connection.
• Configure a peer.
• Control outputs on a peer.
• Listen to a peer that is on another network.
The module can only listen to peers on the backplane or local
DeviceNet network.

Configuring POINT I/O and ArmorPOINT I/O DeviceLogix modules using RSNetWorx for DeviceNet
• Consume data from a safety connection
The module can consume data from a safety module with a standard
connection.
• Consume data sent to a peer from a master.
Set Up Peer Communication Parameters
For each peer, you need to configure a set of parameters.
Here are the three parameters in their default settings (no peer data).
Parameter
number
31 Peer#0 MacID Slot number No connection
39 Peer#0 Size Input data size 24 bytes
65 Peer#0 EPR Time out value 1000 ms
Parameter

Parameter description Default value
Example
To listen to the data from a 1734-IB4 module in the first slot (node 1), you can
configure the parameters in the following way:
Parameter
number
31 Peer#0 MacID Slot number 1
39 Peer#0 Size Input data size 1 byte
65 Peer#0 EPR Expected packet rate 100 ms
The 1734-IB4 is "Peer#0". Enter its produced data size, "1" as its input data
size. If the module does not consume data from this peer in four times the
expected packet rate (EPR), which is 400 ms in this case, the Peer #0
connection fault bit will be set.
Parameter
name
Parameter description Value
The contents of the data are mapped to the Peer#0 data table.
To use the data from the 1734-IB4 in the DeviceLogix editor, click to
place a Boolean bit input on the function block sheet, and select the desired bit
to use in logic under the "Network Boolean Input" category.
Rockwell Automation Publication 1734-UM015B-EN-E - May 2020 59
Configuring POINT I/O and ArmorPOINT I/O DeviceLogix modules using RSNetWorx for DeviceNet
Select bit0 of byte0. With up to 24 bytes of data available for mapping, the last
entry is "Peer#0 (Byte 23, Bit7)." 192 bits per peer can be used for a total of
1536 data bits.
You are highly encouraged to use the connection status bits to verify that the
device is receiving valid data from the peer. They are located under the Status
Input category of the "bit input" I/O tags.
In our example, "Peer#0 Data Valid" will be set to 1 when the POINT I/O
DeviceLogix module is consuming data from the peer that is timely (which is,
within the EPR timeout) and of the correct length. No other checking is done
on the data by the module.
"Peer#0 Exists" is set to 1 when a peer connection has been configured.
Analog data can also be used in a peer connection. If a 1734-IE4C module is
located in the third slot, you can configure the POINT I/O DeviceLogix
module like this:

Channel 2 is mapped to Word 2. Select this as shown below. For help on
mappings, see Appendix A
.
To use the overrange bit of channel 1, you can use "bit input" I/O tag and
select Peer#1, byte 9, bit 7.
Again, it is best to use the Peer Connection Status bits (Peer#1 Data Valid and
Peer#1 Exists) to validate the data before using it.

Configuring POINT I/O and ArmorPOINT I/O DeviceLogix modules using RSNetWorx for DeviceNet
If the POINT I/O DeviceLogix module is consuming data from a peer that
has double precision analog data (32-bit), like the 1734-VHSC24, the data can
be used in logic by addressing the high-word and low-word separately. By using
math functions (multiply and add), the two words can be combined into one
value.
Produce Data Without Using a Master
See Very High-Speed Counter Input Modules
in Appendix A.
With the POINT I/O DeviceLogix module (and other DeviceLogix modules
that support "ZIP"), you can send data to another listener without a network
master to set up the connection.
The following parameters are used to configure this feature:

(default)
Soon after power-up and getting online, when Auto Produce is enabled, the
POINT I/O DeviceLogix module begins producing change-of-state (COS)
type I/O data on the connected network or backplane. It produces the
selected "Auto Produce Assembly" at the selected "Auto Produce EPR"
(Expected Packet Rate).
The Auto Produce Assembly data can be:
• 20 bytes of produced data (it sends all possible data)
• 8 bytes of produced data (this does not require the fragmentation
protocol, so it will reduce network bandwidth)
• 1 byte of produced data (only the state of the 8 I/O)
A description of these assemblies can be found in Chapter 4.
The Auto Produce EPR sets the cyclic rate at which data is produced if there is
no change of I/O state. If there is a change of state, new data is produced
immediately. If data changes often, to reduce change-of-state traffic on the
network, you can increase the Auto Produce Production Inhibit Time (PIT).
For example, if the PIT is set to 10 ms, the quickest the module can produce
data is once every 10 ms even if there is a change of state.
Auto Produce is only recommended on a DeviceNet network in situations
where a master is not required.

Configuring POINT I/O and ArmorPOINT I/O DeviceLogix modules using RSNetWorx for DeviceNet
Due to the fact that there is no master to verify the connection and the
configuration of each module, it is recommended that the ZIP Security Key be
produced in the data. This unique number is calculated using the identity of
the module and the present configuration. The ZIP Security Key value is in the
DeviceLogix Logic Editor, under the Analog Input I/O tags.
The output of the Analog Input I/O tag can be wired to the input of an
Analog Output I/O tag to map it into the Produced Assembly Image:

In this example, the ZIP Security Key is mapped to Network Output Word 3.
Any module receiving this data should verify the constant value.
For example:
The ZIP Security Key constant is added using the ellipses button of the NEQ
function block. This output can be used to condition the execution of other
function blocks using the Enable input.
Note that there could be an "unsigned value to signed value conversion" when
the ZIP Security Key is displayed in the Logic Editor, which leads to a
mismatch of displayed value. However, the value is consistent in HEX format.

Digital Inputs to Function Blocks
When the Bit Input I/O tag connector is added to the DeviceLogix editor, the
following input options are available:
Hardware
Discrete Input 0 through Discrete Input 7 are the states of the eight I/O
points on the module.
Status
The following is a list of status bits that can be selected. Most will only be used
in a DeviceNet network:
• Explicit Msg Cnxn Exists
• Polled Cnxn Exists
• COS/Cyclic Cnxn Exists
• Polled Cnxn Fault
• COS/Cyclic Cnxn Fault
• Polled Cnxn Idle
•Network Fault
• Minor Module Fault
• Bit-Strobe Cnxn Exists
• Bit-Strobe Cnxn Fault
• Bit-Strobe Cnxn Idle
Rockwell Automation Publication 1734-UM015B-EN-E - May 2020 75
DeviceLogix Capabilities
If you are using the EtherNet/IP or ControlNet adapter, it is suggested that
you use the COS/Cyclic connection status bits to determine the health of the
connection with a master.
The following are the status bits for the eight Peer connections:
• Peer#X Data valid
• Peer#X Exists
Use the Exists bits to determine if a connection is configured, and the Data
Valid bit to check if the data from the peer has been received in the expected
time (EPR) and with the expected data size.
Network
Network Input 0 through Network Input 7 are sent to the DeviceLogix
program through the Output Data assembly byte 1. In RSLogix 5000, the tag
name for these bits is UserDefinedBitData.
Reserved Bit 8 through Reserved Bit 31 are legacy bits and should not be used.
There are many Peer#X (Byte X Bit X) bits. This is a mapping of 24-byte bit
data for the eight peer connections. You need to know the Input Memory map
of each of the peers in order to use this data. See Appendix A
.

Analog Inputs to Function Blocks
When the Analog Input I/O tag connector is added to the DeviceLogix editor,
the following options are available.
Network Analog Input
Network Input Word 0 through Network Input Word 7 are sent to the
DeviceLogix program through the Output Assembly. In RSLogix 5000, the tag
name for these words is UserDefinedWordData[0..7].
The ZIP Security Key defines a unique number that can be sent to a peer to
verify the identity and configuration of the module. The ZIP key can be
directly tied to a Network Output Word in the DeviceLogix program.
Peer#x (Word x)
There are eight groups of peer data (0…7) and 12 words within each group.
These are the eight peers and up to 24 bytes of data mapped from each peer.
You need to know the input data map from each peer to know what data to
use. See Appendix A

Enable Line feature
The Enable Line feature 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 Enable Line is on;
otherwise, that instruction maintains the data from the last data scan. In this
manner, functions can be executed conditionally based on the state of the
Enable input. Under normal conditions, the Enable output will have the same
value as the input, passing the enable information to the next instruction.
Certain error conditions that occur within the processing of a function block
may cause the Enable output to go false.
If the Enable Line feature is used, EnableIn can be connected to an input I/O
tag or the output of another function block. The EnableIn input will retain the
value of the source that it is bound to.
If the Enable Line feature is not needed, the EnableIn input can use a constant
value which can be set on each instruction’s property page. By default, this
constant will allow execution of the function.

Editing of the configuration and DeviceLogix program can be done off-line
and saved in the DNT file created by RSNetWorx for DeviceNet. The
changes, however, must be manually downloaded to the module while online.
When using RSLogix 5000 with an EtherNet/IP or ControlNet adapter, the
forward open to the DeviceLogix module does not contain any configuration
information. The configuration must be sent via RSNetWorx for DeviceNet
while online.
The I/O module will save the configuration and DeviceLogix program locally
(inside the module). You will only need to download the configuration once. If
you replace the device, you need to download the configuration to the new
module.
Before the DeviceLogix program executes, it must be enabled. You can do this
using the Editor while online. For details, see Enable/Disable Logic
.
Alternatively, you can use the owning processor to enable the program. For
details, see Messaging
.

DeviceLogix Capabilities
Enable/Disable Logic
For logic to execute, it must be enabled. While editing online with RSNetWorx
for DeviceNet, you can enable 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 program. 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.
Dependent Mode
Logic will also be enabled or disabled if the Dependent Mode parameter is
Enabled. In this case, logic will execute following the state of the owning
connection. When the connection is in RUN, the logic is enabled. When the
connection is in Idle, Fault, or non-existent, logic is disabled.
You can also enable or disable logic through explicit messages from the
owning controller. See Messaging
.

IMPORTANT
Function block instances
Messaging
There are certain parameters that you may want to SET or READ from the
module that are not part of the I/O Assemblies. Those parameters are still
available through messaging.
This section contains advanced user information. You should understand the
CIP object model and be familiar with the terms Service, Class, Instance, and
Attribute.
This section discusses how to SET and READ information from the Timer
and Counter function blocks and how to enable and disable logic with the
Logic Supervisor Object.
The first thing that is important to know is that each function block has a
handle or an instance number. This instance number is assigned by the editor,
it can be found in the upper left corner of the function block.
The instance number can change if you edit the program. It may also be
different from module to module. Verify the instance number before using
messaging.
For devices running firmware revision 4 or higher, each
instruction instance ID number is assigned once and will never
change.
84 Rockwell Automation Publication 1734-UM015B-EN-E - May 2020
DeviceLogix Capabilities
To access the information, you need the “address” of that information. The
address is made up of the Class Code, the instance (as discussed above), and
the attribute.
The following table shows this data for the Logic Supervisor, Timer, and
Counter function blocks.

Troubleshooting
Troubleshooting Scenarios
The following are scenarios that you may encounter while using the modules.
Peer connection is not working
If the Network Status LED is flashing red, one or more connections to the
device are broken or not functioning properly. If the device has been
configured to consume data from peers, it is possible that the data size or data
rate have not been configured correctly.
• Use the Peer Missing bits in the I/O assembly to check which peer
connection is missing.
• Verify the configuration is correct. Upload from the module into
RSNetWorx for DeviceNet.
• Verify the Node number or Slot number is correct.
• Verify the connection size is correct.
• Increase the EPR (Expected Packet Rate).
• Verify that the owner of the connection to the peer (usually a scanner or
controller) is receiving data. The DeviceLogix module cannot make a
connection to a peer; it can only listen to COS (Change-of-State) I/O
data going from the peer to the master.
92 Rockwell Automation Publication 1734-UM015B-EN-E - May 2020
Troubleshooting
Configuration or DeviceLogix program cannot be downloaded to the module
A DeviceLogix program and most configurable parameters cannot be changed
while the DeviceLogix program is running or when an I/O connection is
active.
• Inhibit the connection in RSLogix 5000 (if using EtherNet/IP and
ControlNet).
• Disable logic in RSNetWorx for DeviceNet before downloading.
Rockwell Automation Publication 1734-UM015B-EN-E - May 2020 93
Troubleshooting
• Clear the Node Active checkbox in RSNetWorx for DeviceNet (if using
a DeviceNet scanner or DeviceNet adapter).
Module’s DeviceLogix program exits the Run mode unexpectedly
The module’s DeviceLogix program exits the Run mode unexpectedly. A
possible reason may be that the ADR feature of the scanner is turned on and
the ADR data of the module stored in the scanner is not consistent with what
is on the module. When the scanner establishes connection to the module, it
will verify the configuration in itself with what is in the module. Any mismatch
would result in the scanner downloading its saved ADR data to the module.
• Check the ADR feature of the network scanner and verify if the
configuration stored in the scanner is the most recent and correct
version.

Appendix A
About This Appendix
Peer I/O Sizes
This appendix contains information to help you use peer data from
POINT I/O and ArmorPOINT I/O modules in your DeviceLogix program.
For descriptions or details on the individual modules, refer to the Installation
Instructions or User Manual for the specific modules.
The following tables list the produced I/O sizes of the digital and analog input
modules, including those of the POINT I/O and ArmorPOINT I/O
modules.
Only the input modules are listed below. The data sent to or consumed by
output modules cannot be used in Peer data connections. Although it is
possible to read the status information produced from some output modules,
they are not included here for the sake of brevity. If another module’s output
data is required in your DeviceLogix program, it is suggested that this data be
sent from the owning master to the DeviceLogix module through the output
(consumed) data assembly.
