Example 3

If the 100 tags have data offsets of 11 to 110, the tags will be represented by one tag group: tag group 1. In this case a single request will have to be made to read the values for the 100 tags.

While it may not always be possible to configure tags in a manner in which the absolute minimum number to tag groups are required, it is important to try to configure the tags in a way in which as much optimization can be achieved as possible. Since performance is heavily dependent on the amount of time it takes to communicate with a Modbus device, the fewer the number of requests and corresponding responses required the better.
