If the 200 tags have data offsets of 1 to 40, 51 to 90, 101 to 140, 151 to 190 and 201 to 240 respectively, the tags will be represented by five tag groups. The following table represents the five tag groups and the consecutive offsets in each group:

Tag group

Tag offsets

1

1 to 40

2

51 to 90

3

101 to 140

4

151 to 190

5

201 to 240

In this case five requests will have to be made to write the values for the 100 tags.
