The Timed Loop structure and VIs and VI Server properties and methods can return the following error codes. Refer to the KnowledgeBase for more information about correcting errors in LabVIEW.
| Code | Description |
|---|---|
| −842 | The timed structure failed to unreserve the NI Scan Engine. An error occurred while trying to close a transaction with the NI Scan Engine. |
| −841 | The timed structure failed to retrieve the NI Scan Engine mode. Terminals bound to CE state will be undefined |
| −840 | The timed structure failed to reserve the NI Scan Engine. An error occurred while trying to open a transaction with the NI Scan Engine. |
| −832 | The Priority Mapper Table is full. Timed structures must use one of the existing priorities already in the Priority Mapper Table. |
| −831 | Timing Source Fire Count Overflow The timing source has been triggered MAX_U64_VALUE times, and cannot fire again. You must clear and recreate the timing source. |
| −830 | Invalid Trigger ID The trigger ID cannot be less than 0 or greater than 128. |
| −826 | A time-critical VI contains a timed structure. You cannot place a timed structure in a time-critical VI. The priority schemes would conflict and cause the timed structure to operate unreliably. |
| −825 | Invalid CPU Specified for timed structure. Invalid CPU specified for timed structure. The CPU must fall within the range of 0...N-1, where N is the number of CPUs in the system. Additional valid entries include -2 (automatic assignment) and -1 (no change). |
| −823 | Cannot load Timed Loop Scheduler Dynamic Library. |
| −822 | The timed structure feature or type is not supported on the current platform for the following timing source. |
| −821 | The following timed structures timed out while waiting for the synchronization group to synchronize all timed structures in the group. |
| −820 | The following timed structure has been initialized with illegal parameters. |
| −819 | An illegal mode has been specified for the following given Timed Loop. |
| −818 | An illegal period, priority, deadline, offset, or start has been specified for the following timed structure. |
| −817 | Timing Source error or attempted to execute another iteration of a Timed Loop that was already aborted due to an error of the following timing source. |
| −816 | Timed structure aborted or attempted to execute another iteration of the following aborted Timed Loop. |
| −815 | Cannot add timing source to the following active timing source hierarchy. |
| −814 | Cannot add timed structure to the active timed structure synchronization group. |
| −813 | The following timing source can be assigned to only one timing source hierarchy at a time. |
| −812 | The following timed structure can only be assigned to one timed structure synchronization group at a time. |
| −811 | The given name is already being used by another timing source hierarchy: |
| −810 | The given name is already being used by another timed structure synchronization group: |
| −809 | The given name is already being used by the following timing source. |
| −808 | The given name is already being used by the following timed structure. |
| −807 | LabVIEW: The following timing source hierarchy does not exist possibly because the timing source hierarchy has never been created, has been cleared, or an illegal action was attempted. |
| −806 | LabVIEW: The following synchronization group does not exist possibly because the synchronization group has never been created, has been cleared, or an illegal action was attempted. |
| −805 | LabVIEW: The following timing source does not exist. This error might occur because the timing source was never created, has been cleared, or an illegal action was attempted. Use the Create Timing Source VI to create a Timed Loop timing source. |
| −804 | The timed structure does not exist, possibly because the timed structure has not been created, the timed structure has been cleared, or an illegal operation was attempted. |
| −803 | Creating a new timing source hierarchy exceeds the maximum allowed number of simultaneously active timing source hierarchies. |
| −802 | Creating another timed structure synchronization group exceeds the maximum allowed number of simultaneously active synchronization groups. |
| −801 | Creating another timing source exceeds the maximum allowed number of simultaneously active timing sources. |
| −800 | Creating another timed structure exceeds the maximum allowed number of simultaneously active timed structures. |
| 824 | You must supply a mode to change the offset of the Timed Loop. |
