Module Faults: 16#ff00 - 16#ffff

TUV
Code
String
Explanation and Possible Causes/Solutions
16#ff00
Connection Request Error: No connection instance.
The controller is attempting to set up a connection with the module and has received an error.
Verify that the physical module is the same module type (or is a compatible module) as created in the software.
If the module is a 1756-DHRIO module in a remote chassis (connected via a ControlNet network), verify that the network has been scheduled with
RSNetWorx
 software.
Even after the network has been scheduled with
RSNetWorx for ControlNet
 software, if you are online and if the 1756-DHRIO module is configured for
DH+
 network only, a #ff00 Module Fault (no connection instance) may occur. The module is properly communicating even though Faulted is displayed as its Status on the Module Properties dialog box. Disregard the error message and fault status and continue.
16#ff01
Connection Request Error: Path to module too long.
The controller is attempting to set up a connection with the module and has received an error.
Verify that the path to this module is a valid length.
16#ff04
The remote controller’s map instance attempted to access a connection while being in an invalid state.
16#ff08
Connection Request Error: Invalid path to module.
The controller is attempting to set up a connection with the module and has received an error.
Verify that the path to this module is a valid length.
16#ff0b
Module Configuration Invalid: bad format.
Either:
  • 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 passed the electronic keying test. This may result when Disable Keying or Compatible Module options were used in the module configuration instead of the Exact Match option.
    Despite passing the electronic keying test, the module being connected to 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.
16#ff0e
Connection Request Error: No connections accepted to bridge.
The controller is attempting to set up a connection with the module and has received an error.
