Always Allow Automatic Configuration

ATTENTION:
Select the Always Allow Automatic Configuration option only if the entire CIP Safety Control System is not being relied on to maintain SIL 2 or SIL 3 behavior during the replacement and functional testing of a device. Do not place devices that are in the out-of-box condition on a CIP Safety network when the Always Allow Automatic Configuration option is selected, except while following this replacement procedure.
When the Always Allow Automatic Configuration option is selected in the controller project, the controller automatically checks for and connects to a replacement device that meets all the following requirements:
  • The controller has configuration data for a compatible device at that network address.
  • The device is in out-of-box condition or has an SNN that matches the configuration.
If the Always Allow Automatic Configuration option is selected, follow these steps to replace a safety I/O device.
  1. Remove the old I/O device and install the new device.
    1. If the device is in out-of-box condition, go to the last step in this procedure. 
      No action is needed for the
      GuardLogix®
       controller to take ownership of the device.
    2. If an SNN mismatch error occurs, go to the next step to reset the device to an out-of-box condition.
  2. Right-click the safety I/O device and select Properties.
  3. In the navigation pane, select Safety.
  4. Click Reset Ownership and click OK.

  5. Follow your company-prescribed procedures to functionally test the replaced I/O device and system and to authorize the system for use.
