I/O fault codes Chapter 3
Code Interpretation
#FF0B Possible causes include the following.
• The configuration for the module is invalid.
• The module in use (that is, the physical module) is different than the module specified in the I/O configuration tree and is therefore causing the connection or service
to fail.
The fault may occur even when the module passes the electronic keying test. This may result when Disable Keying or Compatible Keying options are used in the
module configuration instead of the Exact Match option.
Despite passing the electronic keying test, the module being connected does not have the same features or settings as the module specified in the I/O configuration
tree and does not support the connection or service being attempted.
Check the module in use and verify that it exactly matches the module specified in the I/O configuration tree of the Logix Designer application.
For more information about electronic keying, see the user manual for the module you are using.
#FF0E The controller is attempting to set up a connection with the module and has received an error.
