DF1 Master Poll Group Size Error
Allen-Bradley · Compact 5000 I/O Serial Module
What does I x .DF1Master.PollGroupSizeError mean?
This boolean tag for DF1 Master module 'x' indicates a configuration error where the defined Normal Poll Group size exceeds the maximum allowable number of nodes for normal polling. A value of 1 signifies that the polling configuration is invalid and cannot be executed as specified, leading to polling failures for normal nodes.
Common Causes
- The number of nodes configured in the `Ox.DF1Master.NormalPollNode` array is greater than the value specified in `Ox.DF1Master.MaxNormalPollNode`.
- An attempt was made to add more nodes to the normal polling list than the system's current configuration or hardware supports for module 'x'.
Repair Steps & Checklist
Click steps to track your progress.
- 1
Adjust the size of the `Ox.DF1Master.NormalPollNode` array in the module definition within Logix Designer, ensuring it is less than or equal to the value of `Ox.DF1Master.MaxNormalPollNode`.
- 2
If more normal poll nodes are required, review the `Ox.DF1Master.MaxNormalPollNode` parameter. If system hardware for module 'x' supports it, increase its value in the module configuration, then reconfigure the polling list.
