A poll group can be configured by associating a polling driver with each communication driver tag that you wish to belong to the group. For example, if you wish to configure 3 communication driver tags to belong to the same poll group:
Create a new polling driver tag for each communication driver tag, and configure each as follows.
Select the communication driver tag's name in the I/O Device field on the I/O tab of the polling driver. There should be one polling driver associated with each communication driver tag.
Enter the same text in the Poll Group Name field on the I/O tab of each polling driver (e.g. Eastern Poll Group).
Enter an appropriate sequential number in the Poll Sequence Number field for each of the polling driver tags. This will identify each polling driver tag's place in the poll sequence for the identified poll group. (For example, enter 1 for the first polling driver tag in the Eastern Poll Group, 2 for the second polling driver tag in the Eastern Poll Group, and 3 for the final polling driver tag in the Eastern Poll Group.
Note: If a situation should arise where two or more polling driver tags belonging to the same poll group have been given the same Poll Sequence Number, VTScada will determine the poll order and will consistently repeat it.
