Chapter 1

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 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 55.

Product Features • Mechanically compatible with all 856T base mount adapters to offer

vertical, surface, pole, and tube mounting options

• 70 mm external diameter

• Visible status indicator that shows the result of the device self test at

powerup.

• IP66/67 rated enclosure

• IO-Link 1.1 communication protocol compliant

• Class B device

IO-Link Features • Built-in counters to allow you to know the number of times a specific

module has been turned ON.

• Operation hours since inception and since powerup that can help you

correlate machine availability.

• Vibration indication to alert you about unusual mechanical behavior

when the IO-Link module detects vibration above certain threshold

values.

• Class A and Class B voltage monitoring

• Short-circuit detection to help protect the circuitry of the device and the

master from a light or sound module short circuit.

• Open load condition useful to indicate when light or sound modules in

the stack light have not been properly installed.

• Premier integration design that enables configuration via the

Rockwell Automation® IO-Link master Add-on Profile.

• Automatic Device Configuration that helps you replace the device

quicker, if necessary.

10 Rockwell Automation Publication 856T-UM001B-EN-P - April 2021

Chapter 1 Product Overview

• 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.

Installation

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.

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.

Figure 1 - Mount the IO-Link Module

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.

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.

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.
