Chapter 1 Introduction
• The maximum current that any pin on the M12 L-coded power connectors can carry is
16 A.
• Confirm that the external module power supply is adequately sized for the total current
draw of the module power bus in the system.
• Not all power supplies are certified for use in all applications, for example,
nonhazardous and hazardous environments.
Module and Device
Configuration
You must create a Studio 5000 Logix Designer application project for the controller that owns
the ArmorBlock 5000 8-channel IO-Link master module and the IO-Link devices. You can
configure the IO-Link master module and the IO-Link devices in the project.
The Studio 5000 Logix Designer application transfers the project to the controller during the
program download.
For more information on how to configure an IO-Link master module or IO-Link device, see the
following:
• Configure the IO-Link Master Module
on page 39
• Configure the IO-Link Device on page 61
Module and Device
Operation
Both the IO-Link master module and IO-Link device operate through connections. Connections
work in either cyclic mode or Change of State (COS) mode.
Requested Packet Interval
The Requested Packet Interval (RPI) is a configurable parameter that defines a specific rate at
which the controller exchanges data with the IO-Link master module or IO-Link device.
You set the RPI value during initial module or device configuration and can adjust it as
necessary after operation has begun.
For more information on guidelines for specifying RPI rates, see the Logix 5000 Controllers
Design Considerations Reference Manual, publication 1756-RM094
.
Cyclic Mode
All connections work in cyclic mode, except for input event connections. In cyclic mode, both
the IO-Link master module and the IO-Link device send input data at the time that is defined in
the Requested Packet Interval (RPI). Similarly, the controller sends output data at the time that
is defined in the RPI.
ATTENTION: You must use two separate SELV-listed power supplies or one
SELV-listed power supply with two pairs of separately isolated terminals for
module power.
IMPORTANT You can change the RPI while the project is online. If you change the RPI
while the project is online, however, the connection to the IO-Link
master module or IO-Link device is closed and reopened in one of the
following ways:
• You inhibit the connection to the module or device, change the RPI
value, and uninhibit the connection.
• You change the RPI value. In this case, the connection is closed and
reopened immediately after you apply the change to the module or
device configuration.
