0x0006 Partial data transferred.
Only part of the expected data was transferred.
Possible causes include the following:
• The response buffer is too small to handle the response
data.
• 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 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 that is specified in the application. For more
information about electronic keying, see the user manual
for the module you are using.
0x0007 Messaging connection lost. The messaging connection was lost. A service request is unconnected, but should be connected.
0x0008
Service Request Error:
Unsupported Service.
The controller is attempting to request a service from the
module that is not supported by the module.
Possible causes include the following:
• 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 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 that is specified in the application. For more
information about electronic keying, see the user manual
for the module you are using.
0x0009
Module Configuration Rejected:
parameter error.
The configuration for the module is invalid. The module
configuration may have been changed in the Data Monitor or
programmatically.
• Additional fault information for this fault will be displayed
as a hex code on the Connections tab. If available for the
module, open 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 the module is connected.
• Verify that the configuration is valid by using the module
configuration software to validate your configuration.
Consult the module user manual for a list of fault codes to
determine the configuration parameter that is in error.
0x000B
Object already in requested
mode or state.
The object is already in the mode/state being requested by
the service.
You do not have to request a mode/state because the object
is already in the requested mode/state.
0x000C
Service Request Error:
Invalid mode or 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.
For an I/O module, this may indicate that the module has
one of the following conditions:
• Limited communication is possible, but the module has a
Major Fault.
• A firmware update needs to be completed or is currently
being completed.
See the Module Info tab to determine the exact cause.
0x000D Object Already Exists. An object instance is created where the instance exists. Use another object instance number.
0x000E Attribute value not settable.
A MSG instruction is configured to change an attribute that
cannot be changed.
See the device user manual for available programming
options.
0x000F
Access permission denied for
requested service.
A MSG instruction has been configured to delete a map
object that cannot be deleted.
See the device user manual for available programming
options.
0x0010
Mode or state of module does
not allow object to perform
requested service.
The state of the device prevents a service request from
being handled.
See the device user manual for available programming
options.
0x0011 Reply data too large.
The reply to a message has a data size that is too large for
the destination.
Change the destination to a tag that can handle the data
size and type being returned.
