Check the connection use of the controller or communication module. If all of the connections are used, try to free some of the used connections or add another module to route the errant connection through.

Check the number of controllers making a connection to this I/O module and verify that the number of connections is within the limits of the I/O module.16#0005Connection Request Error: Bad ClassThe controller is attempting to make a connection to the module and has received an error. Either:

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#0007Connection Request Error: Bad Class.A service request is unconnected, but should be connected.16#0008Service Request Error: Unsupported ServiceThe controller is attempting to request a service from the module that is not supported by the module.16#0009Module Configuration Invalid: parameter error.

Tip: Additional Fault Information for this fault will be displayed as a hex code on the Connection Tab.The configuration for the module is invalid. The module configuration may have been changed in the Data Monitor or programmatically.

If available for the module, access the Connections tab of the Module Properties dialog box for the additional fault code. The additional fault code indicates the configuration parameter that is causing the fault. You may have to correct multiple parameters before this fault is cleared and connection is properly established.16#000AAn attribute in the Get_Attributes_List or Set_Attributes_List has a non-zero status.Either:

If an object attribute or tag is invalid, export the Logix Designer file, then re-import it. Reschedule the ControlNet network after re-importing if applicable.16#000CService Request Error: Invalid mode/state for service request.The controller is attempting to request a service from the module and has received an error. First, verify that the module is not faulted.

A firmware update needs to be completed or is currently being completed. Refer to the Module Info tab to determine the exact cause.16#000DObject already exists.An I/O map instance is created where the instance is already in use.16#000EAttribute value cannot be set.A MSG instruction is configured to change an attribute value that cannot be changed.16#000FAccess permission denied for requested service.A MSG instruction has been configured to delete a map object that cannot be deleted.16#0010Mode or state of module does not allow object to perform requested service.The state of the device prevents a service request from being handled.16#0011Reply data too large.The reply to a message has a data size that is too large for the destination.

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#0106Connection Request Error: Module owned and configured by another controller. Module may accept only one connection if Unicast is used.An ownership conflict occurred for the connection. One of these conditions exists:

The Connection Request to this module has been rejected due to an Ownership conflict with another Owner (for example, another Controller). This may occur with modules such as output modules that only allow a single Owner to configure and control its outputs.

Configure both the Owner and the Listen-Only connection as Multicast.16#0107Connection Request Error: Unknown type.A connection being accessed was not found.16#0108Connection Request Error: Connection type (Multicast/Unicast) not supported.The controller is requesting a connection type not supported by the module. One of these conditions exists:

The fault may occur even when the module passed the electronic keying test. This may result when Disable Keying or Compatible Keying options were used in the module configuration instead of the Exact Match option.

You may have configured a consumed tag to use a Unicast connection, but the producing controller does not support Unicast connections.16#0109Connection Request Error: Invalid connection size. Tip: Additional Error Information for this fault will be displayed as the tag name associated with the

the fault may occur even when the module passed the electronic keying test. This may result when Disable Keying or Compatible Keying options were used in the module configuration instead of the Exact Match option.

This controller is not an Owner of this module because it is attempting to establish a Listen Only connection, which requires no module configuration. It cannot connect until an Owner configures and connects to the module first.16#0111Requested Packet Interval (RPI) out of range.Either:

See the Connection tab in the Module Properties dialog box for valid RPI values.16#0113Connection Request Error: Module connection limit exceeded.The number of connections is greater than what is available on the module. The number of connections must be reduced or the hardware must be upgraded.

Change the Flex I/O communication adapter Comm Format from Input or Output configuration to Rack Optimization. When the Comm Format changes, the adapter must be removed and recreated in the I/O configuration tree.

If the configuration uses messaging over ControlNet, sequence the messages to reduce the number that are executing at the same time, or reduce the number of messages. Messages (MSG instructions) also use connections.16#0114Electronic Keying Mismatch: Electronic keying product code and/or vendor ID mismatch.The Product Code of the actual module hardware does not match the Product Code of the module created in the software.

Electronic Keying failed for this module. You may have a mismatch between the module created in the software and the actual module hardware.16#0115Electronic Keying Mismatch: Electronic Keying product type mismatch.The Product Type of the actual module hardware does not match the Product Type of the module created in the software.

Electronic Keying failed for this module. You may have a mismatch between the module created in the software and the actual module hardware.16#0116Electronic Keying Mismatch: Major and/or Minor revision invalid or incorrect.The Major and/or Minor revisions of the module do not match the Major and/or Minor revisions of the module created in the software.

Electronic Keying failed for this module. You may have a mismatch between the module created in the software and the actual module hardware.16#0117Connection Request Error: Invalid Connection Point. Tip: Additional Error Information for this fault appears as the tag name associated with the controller to

Another controller owns this module and has connected with a Communications Formats: I/O modules different than the one chosen by this controller. Verify that the Communications Format chosen is identical to that chosen by the first owner controller of the module.

The controller may be attempting to connect to a nonexistent tag in a producing controller.16#0118Module Configuration Rejected: Format error.An invalid configuration format is used. One of these conditions exists:
