IP-IO Module Reset Modes

You can reset and restart the IP-IO modules in different ways depending on how long you press the reset button. The resets and restarts can affect the retention of values after restart based on the retain levels configured for the variables.

You can use a straightened segment of a paper clip or a similar tool to press the reset button.

Table: Reset Modes

Mode

Description

Warm start

Press and release the reset button in less than 5 seconds.

Performing a power cycle in a SmartX IP controller is analogous to a hardware warm start.

Cold start

Press and hold the reset button for more than 5 seconds but less than 9 seconds.

Network reset

Press and hold the reset button for 10 to 19 seconds.

Perform a network reset in WorkStation in order to reset the IP address settings to DHCP with a failover to Auto-IP.

Factory reset

Press and hold the reset button for 20 to 29 seconds.

Consult the following Factory Reset subsection for more details.

Erase database

Press and hold the reset button for 30 to 39 seconds.

Cancel reset action

Press and hold the reset button for more than 40 seconds and then release the button.

Performing this action cancels the reset request that would be initiated by any of the shorter button press durations.

Tip:

If the IP-IO module is equipped with the MP-C Display add-on module, a count-up timer and progress bar are displayed to assist in reset selection. There is also a reset mode indicator that lets you know which reset occurs if you release at that time.

Factory Reset

In WorkStation, if your SmartX IP controller device seems completely unresponsive, perform a factory reset to restore the device to a state where it can be successfully commissioned. After you release the reset button, a factory reset may take up to 30 seconds to process. All diagnostic logs and the database are erased during a factory reset. By contrast, controller firmware does not revert and remains at the same active level.

Tip:

 After a physical factory reset in a SmartX IP controller, any controller proxy object in the EcoStruxure BMS database that carries the serial number of that controller may trigger an automatic association. This association occurs between the reset physical controller and the controller proxy object in the EcoStruxure BMS database.

For more information, see Automatic Association after a Factory Reset in a SmartX IP Controller .

Retain Levels for Variables

Variables have a configurable retain level, which controls if the value of the variable is retained after a restart of the IP-IO module. There are three retain levels:

  • No

  • Warm start

  • Cold start

The following table lists what is retained after a warm start or cold start based on the configured retain level.

a Default value is the value the variable gets when it is created.

For more information, see Retain Level .

Tip:

Although variable values in IP-IO modules are retained in accordance with this matrix, SmartX server retention behaves differently. As a result, variable values retained in the server that are not retained in the IP-IO module may be restored to the module during a download command. For more information, see Retain Level .

Value Retention on Restarts Using Command Priority Levels

When you configure the restart retain level for an object with command priority levels, it is recommended that you base retention exclusively on either of the following:

  • The value property configured by using the Configure button

     
    action_zoom_plus_stroke
    for that property in the Basic tab of the object.

  • The command priorities configured by the Configure button

     
    action_zoom_plus_stroke
    for the appropriate command priority levels in the Command tab of the object.

Do not configure retention for both the value property on the Basic tab and the command priorities of the object because doing so may result in unexpected behavior following a controller restart. For example, if the value property is configured to retain during a restart, then that value is written to priority 16 following the restart, regardless of the retain level of priority 16.
