Since the interface will assemble related tags with contiguous data offsets into groups in order to maximize the number of tag values requested in a single Modbus write command, it is best for the user to configure related tags in a manner in which tag groups can be leveraged to minimize the number of requests to write the tag data. In other words, the more related tags whose data offsets are contiguous, the better.
For example, assume that a user creates 200 tags with the attribute values specified in the following table:
|
Point attribute |
Description |
Value |
|---|---|---|
|
Instrument Tag |
Ethernet node |
COM3 |
|
Location2 |
PLC Node |

Location3 |
