If the 200 tags have data offsets of 101 to 300, the tags will be represented by two tag groups: tag groups 1 and 2. The following table represents how the tags will be located in the two groups:

Tag group

Tag offsets

1

101 to 223

2

224 to 300

In this case two requests will have to be made to read the values for the 100 tags since the maximum number of values in a single write request is 123.
