Product Overview
The 856T-B24LC module allows the control and configuration of a standard
856T stack light via the IO-link protocol. This configuration helps your save
time and money in wiring, commissioning, and startup of the entire stack
light while providing access to valuable real-time diagnostics and prognostic
information.
Operation Modes
Product Features
The 856T-B24LC module is compatible with the current light and sound
modules that are offered in the standard 856T product line. The 856T-B24LC
module is capable to control up to seven modules in the stack light
arrangement. The maximum number of light and sound modules in a stack
light configuration depends on the number of circuits that are used
individually by the specific light or sound module (up to seven per 856T-B24LC
module). A summary of all 856T light and sound modules that can be controlled
with the 856T-B24LC module is shown in Table 12 on page 57.

Installation
Embedded IODD file in the device saves configuration time because
there is no need to find this file somewhere else. This file also makes
IODD registration quicker.
Process Data Maps allow for selection of the type of information that is
continuously sent to the PLC as a process data parameter.
Internal temperature indication that helps to understand changes in the
temperature of the application environment.
IMPORTANT
The 856T tower light product family (including the 856T-B24LC module)
is designed for general signaling applications and should not be wired
to any safety circuit in the application.
The 856T-B24LC module is mounted without the use of a tool in any of the 856T
standard base mount adapters that are shown in Figure 2.
For a good mechanical fit, the module provides a haptic feedback (click) only
when it is fully twisted onto the base mount adapter.
IMPORTANT
Verify that the right edge on the alignment mark (triangle shape) in the
856T-B24LC module is aligned with the arrow mark on the base mount
adapter as shown in Figure 1.
The 856T-B24LC module encloses the 5-pin M12 connector on the bottom of the
device and accepts standard cordsets to connect to an IO-Link Master Class B.

IMPORTANT
Physical protection of the stack light is recommended where the
possibility of unwanted access or damage to the device exists in the
application. You should also consider the use of conduit to shield the
cable to avoid cable or wiring cuts.
IMPORTANT
Since the IO-Link protocol is not encrypted or authenticated, you should
protect the cabling and the connectors in both the IO-Link master and
the 856T-B24LC module to help prevent unwanted access when a
distributed control architecture is used. When the device is installed on
top of a control panel, the panel enclosure must provide protection
against unwanted accessibility to the cabling.

When power is applied to the device, the module runs a self-test routine to
verify the health of its internal electronic components and the result of this test
is visible via a bicolor status indicator that is mounted inside the module but
visible from the top. In addition, this status indicator also displays if the device
is communicating with the IO-Link Master. For more information on these
results, see Power On Self Test (POST) on page 43.

IO-Link Overview
IMPORTANT
What is IO-Link?
This chapter provides a short overview of IO-Link technology. For more
details, see the IO-Link specification at io-link.com.
The IO-Link technology is an open point-to-point communication standard
and was launched as (IS) IEC 61131-9. IO-Link is now the first globally
standardized technology for sensor and actuator communication with a
fieldbus system. This technology provides benefits to both OEMs and end
users.
IO-Link provides communications-capable sensors to the control level by a
cost-effective point-to-point connection. IO-Link provides a point-to-point
link between the I/O module and device that is used for transferring detailed
diagnostics, device identity information, process data, and parameterization.
IO-Link communication is based on a master-slave structure in which the
master controls the interface access to the sensor. The option of using the
intelligence that is integrated into the sensor provides you with new methods
to commission your device. Benefits of IO-Link technology range from
reduced installation time during startup to increased diagnostics over the
lifetime of the machine. Other benefits of IO-Link technology include:

How Does IO-Link Work?
Faster programming during initial setup
More efficient troubleshooting process-data tags are named based on the
information they provide
Easily monitor device data though intuitive tag names
IO-Link delivers data over the same standard field cabling used today. By
connecting an IO-Link device to an IO-Link master, the field-device data and
diagnostics are accessible. So, go beyond detecting products on the machinenow the health of the machine can be monitored as it runs.

Rockwell Automation Publication 856T-UM001C-EN-P - December 2021
Chapter 2
IO-Link Overview
Transmission Rates
Three communication rates are specified for the IO-Link device:
•
•
•
COM1 = 4.8 kBd
COM2 = 38.4 kBd
COM3 = 230.4 kBd
An IO-Link device typically supports only one of the specified transmissions
rates (see IO-Link Specifications on page 55). IO-Link V1.1 specification
requires an IO-Link master to support all three communication rates.
Transmission Quality
The IO-Link communication system operates at a 24V level. If a transmission
fails, the frame is repeated two more times. If the transmission fails on the
second try, the IO-Link master recognizes a communication failure and
signals it to the controller.
Response Time of the IO-Link System
The device description file (IODD) of the device contains a value for the
minimum cycle time of the device. This value indicates the time intervals at
which the master addresses the device. The value has a large influence on the
response time. In addition, the master has an internal processing time that is
included in the calculation of the system response time.
Devices with different minimum cycle times can be configured on one master.
The response time differs so for these devices. When configuring the master,
you can specify a fixed cycle time (minimum of 3 ms) and the device-specific
minimum cycle time that is stored in the IODD. The master then addresses the
device that is based on this specification. The typical response time for a device
therefore results from the effective cycle time of the device and the typical
internal processing time of the master.
IO-Link Data Types
There are four data types available through IO-Link:
Process data
Value status
Device data
Events
→
→
→

Cyclic data
Cyclic data
Acyclic data
Acyclic data
Process Data
The process data of the devices are transmitted cyclically in a data frame in
which the device specifies the size of the process data. Depending on the
device, 0...32 bytes of process data are possible (for each input and output). The
consistency width of the transmission is not fixed and is thus dependent on
the master.
Rockwell Automation Publication 856T-UM001C-EN-P - December 2021
15
Chapter 2
IO-Link Overview
Value Status
The value status indicates whether the process data is valid or invalid. The
value status can be transmitted cyclically with the process data.
Device Data
Device data supports device-specific configurable parameters, identification
data, and diagnostic information. They are exchanged acyclically and at the
request of the IO-Link master. Device data can be written to the device (Write)
and read from the device (Read).
Events
When an event occurs, the device signals the presence of the event to the
master. The master then reads out the event. Events can be error messages and
warnings/maintenance data. Error messages are transmitted from the device
to the controller via the IO-Link master. The transmission of device
parameters or events occurs independently from the cyclic transmission of
process data.
Access IO-Link Data
Cyclic Data
To exchange the cyclic process data between an IO-Link device and a
controller, the IO-Link data from the IO-Link master is placed on the address
ranges assigned beforehand. The user program on the controller accesses
the process values using these addresses and processes them. The cyclic data
exchange from the controller to the IO-Link device is performed in reverse.
Acyclic Data
Acyclic data, such as device parameters or events, are exchanged using a
specified index range. The controller accesses these using Explicit Messaging.
The use of the index and subindex ranges allows targeted access.
I/O System Startup
If the port of the master is set to IO-Link mode, the IO-Link master attempts to
communicate with the connected IO-Link device. To do so, the IO-Link master
sends a defined signal (wake up pulse) and waits for the IO-Link device to
reply.
The IO-Link master initially attempts to communicate at the highest defined
data transmission rate. If unsuccessful, the IO-Link master then attempts to
communicate at the next lower data transmission rate.
If the master receives a reply, the communication begins. Next, it exchanges
the communication parameters. If necessary, parameters that are saved in the
system are transmitted to the device. Then, the cyclic exchange of the process
data and value status begins.

Assign Device Parameters
IO-Link Overview
A device that is built for a specific application requires changes to parameter
settings. The device parameters and setting values are contained in the IODD
of the device.
I/O Device Description (IODD) files contain information about the device
identity, parameters, process data, diagnostic data, and communication
properties. These files are required to establish communication with the
sensors via IO-Link.
The IODD consists of multiple data files; the main file and several optional
language files are in XML-format and graphic files are in PNG format
(portable network graphics). These files adhere to the IO-Link open standard,
which means that they can be used with any IO-Link masters.
IODD files are assigned using Studio 5000® and the 1734-4IOL Add-on Profile
(AOP). (a)

AOP Installation
Add-on Profiles (AOPs) are files that you add to your Rockwell Automation
library. These files contain the pertinent information for configuring a device
that is added to the Rockwell Automation network. The Add-on Profile
simplifies the setup of devices because it presents the necessary fields in an
organized fashion. The Add-on Profile allows for the efficient configuration of
systems. The Add-on Profile is a folder that contains numerous files for the
device. It comes as an installation package.
Before you start making a project in Studio 5000, verify that the proper and
latest versions of the AOP files are installed. In this example, you need the AOP
for 1734-AENTR (POINT I/O) and 1734-4IOL (IO-Link Master).
If the AOP is required to be downloaded and installed, you can find it at:

Indicates if an improper light or sound module configuration has been made. The alarm is TRUE
in the following situations:
• You configure a module in a circuit slot without having a module in a preceding circuit slot. For
example, module is selected in circuit 2 without a module being selected in circuit 1.
TRUE= Event triggering alarm occurred
• You allocate too many circuits. For example, three RGB light modules are selected (which
FALSE= Event did not occur
requires nine circuits) and only are seven available.
• If a beacon module, transducer, or recordable sound module is used, it must always be the last
module in the stack as long as there is at least one circuit available. When the Invalid
configuration status condition is active, all outputs in the IO-link module are disabled.

The IO-Link module begins the vibration calibration when a start calibration system command (0xA7) is
received via the IO-Link protocol or by clicking Start Calibration on this AOP tab.
The IO-Link module stops the vibration calibration process when it receives the Cancel calibration
system command (0xA8) via the IO-Link protocol or by clicking Cancel Calibration in this AOP tab. If the
IO-Link module was previously calibrated, after cancellation, the status goes to calibration complete
and uses the previous threshold values. It helps protect against unwanted or accidental Start
Calibration commands.

Power On Self Test (POST)
Critical
A critical hardware fault indicates that the device does not pass critical self-test
checks, therefore ISDU communications is not possible. In this scenario, the
result codes are communicated using the device status indicator only.
Severe
A severe hardware fault indicates that the device passes a minimal set of power
on self test checks allowing execution of its application firmware and
processing of ISDU commands. In this scenario, the result code is
communicated via 'Power On Self Test Status' ISDU command and the POST
alarm is raised via Alarm Status variable. The device status indicator also
communicates this fault.
Device Status Indicator Error Codes
When the firmware of the device detects an error condition, the error code is
communicated by blinking the device status indicator red in the following way:
<start pattern>, <1 s OFF>, <binary error code>, <2 s OFF>, <repeat>
<start pattern> = 100 ms ON, 100 ms OFF, <repeat four more times>
where:
<binary error code> = 4-bit error value, where a 1 is 1 sec ON, and a 0 is
500 ms ON. Each bit is separated by a 1 sec OFF.
The value of the binary error codes are shown in Table 8 on page 43 (for
example, RAM test failed is 0101.)

Class A IO-Link Master Connection Consideration
If the 856T-B24LC module is going to be connected to an Allen-Bradley® IP67

Patchcord
The 856T-B24LC module is a Class B device, however, it can still be used with a
Class A ArmorBlock (1732E-8IOLM12R) IO-Link master if it is connected to one
master port with a Class A to Class B patchcord. The Class A to Class B
patchcord provides up to 500 mA per port on the Master to supply to the
IO-Link module.
The catalog number 889D-F5ACD4M-x-SW patchcord is available in 1, 2, 5, and
10 meter lengths. Replace the x with a 1, 2, 5, or 10 for the required cord length.
Maximum Number of Light/
Sound Modules in the Stack
Light
Although the 856T-B24LC module can control up to seven single-circuit
modules in the stack light, the maximum number of modules must be
determined by calculating the total current consumption (including the
current consumption of the 856T-B24LC module) to make sure that its value is
not above the maximum current that the IO-Link master port can supply.
To calculate this current consumption effectively, see Table 11 on page 56 for
the 856T light and sound module electrical specifications where operating
current consumption is indicated. The current consumption for the IO-Link
module is shown in Table 9 on page 55.
Rockwell Automation Publication 856T-UM001C-EN-P - December 2021
45
Chapter 6
Class A IO-Link Master Connection Consideration
For example, the total current consumption for an IO-Link stack light with
three 856T steady light modules green-amber-red (bottom to top) is:
Total (mA)
Total (mA)
=
=
856T-B24LC

58 mA
+
+
856T-BT5
58 mA
+
+
856T-BT4
58 mA
=
204 mA
Since the maximum current per port in the 1732E-8IOLM12R IO-Link master is
500 mA, the stack light configuration in the previous example can work within
the master parameters.
IMPORTANT
Inrush Current Calculation
If a splitter is used to connect the 856T-B24LC module, then the
maximum total current consumption (856T-B24LC module + light and
sound modules) must not exceed 250 mA.
To minimize total inrush current seen by the IO-Link Master, the 856T-B24LC
module staggers the turn on time of the connected modules. For seven light/
sound modules in a stack light arrangement, this time does not exceed 60 ms.
The inrush current values for each standard 856T light/sound module are
shown in Table 11 on page 56.

856T-BT3
0A

856T-BT5
0A
+
856T-BB4
1.82 A
Since the maximum inrush (1.82 A) at a given time is below the IO-Link master
port (4 A), then this configuration is within the IO-Link master parameters.
Overcurrent Protection
When an overcurrent or short circuit condition in one or more light or sound
modules in the stack light exists, the 856T-B24LC module disables the entire
stack when any of the circuits demands a load current that exceeds 450 mA
(±15%). The first circuit that was detected to cause the short-circuit condition is
indicated by its respective bit number in the Short Circuit Status byte.
The short circuit status bit is only cleared when you attempt to turn the circuit
back ON and the short circuit is no longer present. Since the entire stack is
disabled during a short circuit, the Control Circuit Status (ISDU 0x0134),
reports OFF for all circuits when a short circuit condition exists.
Under a dead short condition, it is possible that the ArmorBlock master port
could be damaged. Therefore, it is recommended to use a 24V DC power supply
that is limited to a maximum current of 5 A.

Device Status
Operational State
The Device Status ISDU 0x0024 (Dec:36) indicates the operational state of the
IO-Link module.
In this case there are five possible scenarios:
Scenario
Device is operating properly
Maintenance required
Out of specification
Functional check
Failure
Description
No faults have been detected on the POST self-test and after that all components
and code routines within the device are working correctly.
The device indicates a state that one or both of the following conditions produce:
• Open circuit due improper assembly of light or sound modules in the stack light.
• Short circuit condition present in one or more of the Light and sound modules in
the stack light.
In both cases, you can correct the situation either by the reassembly of the stack
light or by removing the short-circuit condition.
This state represents a condition where the IO-link module is functioning out of its
design parameters and for practical purposes it refers to a non-optimal voltage or
temperature conditions present in the application.
The device status indicates when the device is running the calibration process
that is required for the vibration indication feature if you have selected it.
This state reflects the results of the POST test that is described in Power On Self
Test (POST) on page 43.

Appendix D
Device Status
Short Circuit
The firmware of the 856T-B24LC module disables the entire stack light when
any of the circuits demands a load current that exceeds 450 mA ± 15% of
current (at least for 40 ms) and is less than 4.5 A ± 15%. In this case, the first
circuit that was detected to cause the short circuit is indicated by its respective
bit number in the short circuit status byte (ISDU= 0x014C 332). Also, the bit
representing that a short circuit condition exists is indicated in the Alarm
status word (ISDU= 0X0135/ 309).
Since the entire stack light is disabled during a short circuit, the
(ISDU=0x0136/ 310) Control Circuit status reports OFF for all circuits when a
short circuit condition exists.
The short circuit status bit only clears when you attempt to turn the circuit
back ON and the short circuit is no longer present.
If the short circuit condition exceeds the 4.5 A ± 15%, then a dead short occurs
and the 856T-B24LC hardware detects it, all outputs are disabled, and the short
circuit status is reported for all the outputs that were ON when the short
circuit occurred. This short circuit detection takes priority over the firmware
detection explained previously.
The short circuit status bit only clears when the short circuit is no longer
present and you attempt to turn each one of the circuits involved back ON.
72
IMPORTANT
The 856T-B24LC short circuit performance may vary depending on the
IO-link master used. For example, a master with rapid short circuit
protection may disable the 856T-B24LC before the short circuit
detection in the 856T-B24LC base takes effect.
IMPORTANT
Remove incoming power before you check connections or replace light
or sound modules in the stack. If you replace one or several light or
sound modules when the respective circuit is energized at the time of
the replacement (hot swap), the situation may cause a temporary short
circuit condition that is indicated in the alarm status word. You must
clear the alarm bit to be in operational mode again.
