Protected Mode For Io-Link Master Module; Enter And Exit Implicit Protected Mode; Enter And Exit Explicit Protected Mode - Rockwell Automation Allen-Bradley ArmorBlock 5000 Series User Manual

Protected Mode for IO-Link
Master Module
You can use the IO-Link master module to capture time stamps. The advantage is that CIP
Sync is system-wide, so time stamp values are consistent across all modules in the system.
Protected Mode is a state where the device is operational, but has implemented defenses
against disruptive changes that would take the product out of service for the process. For
complete information on how Protected Mode works, see EtherNet/IP Network Devices User
Manual, publication ENET-UM006.
There are two types of Protected Mode: Implicit and Explicit. These modes differ in how a
device is entered in such state and what type of action is prohibited in each of these modes.
Implicit Protected Mode is a security enhancement that is automatically triggered as soon as
I/O connection to the module is established.
Explicit Protected Mode is a security enhancement that is triggered when a certain rotary
switches pattern is selected. This security enhancement occurs on the module level and helps
prevent unauthorized configuration changes that can affect system behavior and cause
unintended and unforeseen changes.

Enter and Exit Implicit Protected Mode

The module enters Protected Mode as soon as I/O connections are established to the module.
The module exits Protected Mode as soon as all I/O connections to the module are stopped.

Enter and Exit Explicit Protected Mode

The module enters Explicit Protected Mode when rotary switches are set to value 900 during
powerup.
To enter Explicit Protected Mode, do the following:
1. Note the current position of the rotary switches.
2. Power down the device.
3. Set the rotary switches to 900, then power up the device.
The module confirms entering into Explicit Protected Mode with the following status
indicator flashing sequence:
- Module status indicator = Flashing red
- All other indicators = Off
4. Power down the device and restore previous values to the rotary switches.
5. Power up the device to normal operation with Explicit Protected Mode enabled.
To exit Explicit Protected Mode, do the following:
1. Note the current position of the rotary switches.
2. Power down the device.
3. Set the rotary switches to 000, then power up the device.
The adapter confirms exiting Explicit Protected Mode with the following status indicator
flashing sequence:
- Module status indicator = Flashing red
- All other indicators = Off
4. Power down the device and restore previous values to the rotary switches.
5. Power up the device to normal operation with Explicit Protected Mode disabled.
