Product Details

Forcing the I/O status word is unsuccessful.
When you attempt to force the input status word, the force is unsuccessful though RSLogix 5000 software indicates
the force is enabled.
With firmware revision 18.11, forces are applied as expected.
A velocity spike may occur when a MCCD instruction is executed.
Under certain application conditions, you may see a velocity spike if you are using termination type 4 or 5 with
coordinated moves and you execute an MMD instruction on the last iteration of a move.
For more information about this anomaly, see the Technical Note titled “Possible Velocity Spike When a Motion
Coordinated Change Dynamics (MCCD) Instruction is Executed”, #53928, in the Technical Support Knowledgebase
(available at http://www.rockwellautomation.com/knowledgebase/).
With firmware revision 18.11, the potential velocity spike has been corrected.
Deleting program tags while online is successful, even though they are being referenced by RSLinx software and
should not be deleted.
RSLogix 5000 software and Logix5000 controller firmware provide the ability to delete program tags while online
with the controller. As a precaution, the firmware checks the tag to verify that is not in use (that is, the tag is not
being scanned or referenced) by RSLinx Classic or Enterprise software. If the tag is being used by RSLinx software,
the deletion is not allowed and an error dialog box indicates "Failed to delete tag".
However, with certain tags, the deletion is always allowed - even if the tag is being used by RSLinx software. Tag
types that are always deleted, even if being used by RSLinx software, include:
• Motion Axis
• Motion Group
• Digital Alarm
• Analog Alarm
• Message
With firmware revision 18.11, tags being used by RSLinx software cannot be deleted while online with the controller

Using an SSV instruction to set a task priority of 0 results in unexpected execution times.
If you use a SSV instruction to set a task's priority at 0 (by using the class name Task, attribute Priority), abnormal
task execution times result. This is because tasks cannot have a priority of 0 (permissible priority values are 1…15).
With firmware revision 18.11, you cannot set a task priority to 0 using an SSV instruction. Attempting to set a task
priority to 0 via the SSV instruction results in a minor fault.
Setting the Read/Write Buffer size parameter before enabling the Echo Mode does not result in a message echo.
In the User Protocol tab of the Controller Properties dialog box, if the Read/Write Buffer size is specified before Echo
Mode is checked, the message echo does not execute.
For the message echo to execute, first check Echo Mode, then specify the Read/Write Buffer size.
With firmware revision 18.11, you can specify the Read/Write Buffer size and set the Echo Mode in any order to
achieve a message echo.
