Chapter 4 Common Features of IO-Link Device Integration
Restrictions Imposed By Protected Mode
Protected Mode prevents access to services that are not required after the IO-Link device is
configured and in normal operation. Protected Mode disables features that can make the
device vulnerable to disruptive actions. By doing so, Protected Mode helps to reduce the attack
surface.
When the IO-Link device is in Protected Mode, the device prevents execution of the following
tasks:
• Perform remote device resets
• Perform unconnected messaging to the Service Parameter object of the device
• Perform connected messaging to the Service Parameter object of the device from a
node other than the owner-controller
IO-Link Events The ArmorBlock 5000 8-channel IO-Link master module supports both IO-Link port-level and
IO-Link device-level reporting of IO-Link events.
Table 8
describes the maximum number of events that are supported for each IO-Link port
and IO-Link device.
To enable or disable IO-Link event timestamping for both the port-level and device-level, see
Module Definition
on page 45.
To view the port-level IO-Link event log, see Channels View
on page 49. You can also use the
Event Log object that is defined in the CIP Specification Volume 7C or the S.ChxxChyyDiagEvent
tag for the latest event on the port.
To view the device-level IO-Link event log, use the Event Log object that is defined in the CIP
Specification Volume 7C or the I.LatestEvent tag for the latest event from the device.
For more information on the IO-Link Event Log, see IO-Link Event Log
on page 95.
