To acknowledge the configuration change, do the following:
1. Trigger a rising edge of the ResetConfigChanged tag in the output data to clear the
ConfigChanged tag.
2. In the IO-Link device Module Properties > Configuration view, perform Device
Correlation Check and select "Use Device Values".
3. Review the new values of all parameters.
4. If the new values are appropriate, select Apply to save the values to the project.
Otherwise, select Cancel to revert to the original configuration. Then perform Device
Correlation Check again and select "Use Project Values" to restore the original
configuration to the device.
5. Check that the ConfigChanged bit has changed to 0 to verify that the configuration
change is acknowledged.
If the bit is 1, it means that the external configuration change is still in progress. Repeat
the steps to acknowledge the configuration change and synchronize the project values
and device values of the device configuration.
The ArmorBlock 5000 8-channel IO-Link master module allows you to define message
instructions to send commands to IO-Link devices with the CIP Objects that are defined in the
CIP Specification Volume 7C "Integration of IO-Link Devices into the CIP Architecture". You can
use the IO-Link Service Parameter object to Get or Set IO-Link parameters in the IO-Link
devices in either IO-Link data format or CIP data format.
During IO-Link device operation, sending an excessive number of explicit messages might
cause a delay for IO-Link parameter Get or Set tasks for configuration or operation of the
IO-Link device. Periodic explicit messaging, for example, connected and cached message
instruction, is not recommended.
The maximum number of Class 3 connections that an ArmorBlock 5000 8-channel IO-Link
master module supports is up to 16.
Class 3 connections include Class 3 explicit messaging for the IO-Link master module, Class 3
explicit messaging for IO-Link device, and Class 3 connections that are used for establishing
IO-Link device data connection or reconfiguration.
For connected messaging:
• Up to two concurrent Class 3 connections are supported for every IO-Link device.
• The recommended number of concurrent Class 3 connections for the IO-Link master
module and all attached IO-Link devices is up to 8.
For unconnected messaging:
• Up to two concurrent unconnected messages are supported for every IO-Link device.
• Up to 16 concurrent unconnected messages are supported for the IO-Link master
module and all attached IO-Link devices.
Protected Mode is a state where the IO-Link device is operational and disruptive changes that
would take the product out of service are not allowed.

Enter and Exit Protected Mode

The IO-Link device enters Protected Mode as soon as the connection to the device is
established and exits Protected Mode as soon as the connection to the device is closed.
