Block Operations |
For a good performance on data communication, it is recommended to perform readings with the largest possible number of points in the same Area. When these points are separated into individual Tags, then a single operation occurs for each Tag, while as a Block Tag a single operation occurs for all Tags.
To do so, please consider that the address indicated by the parameters is the initial address and each Block Element corresponds to a single memory position that is a multiple, according to a basic data type relative to a reinterpreted data type.
If the basic data type is Bit and it is configured to be displayed as a Bit, each Block Element represents a bit with their position incrementing one by one. For example, for Y100 on a Block Tag with 3 (three) Block Elements, the first Element is Y100, the second Block Element is Y101, and the third Block Element is Y102.
However, if the basic data type is Bit and it is configured to be displayed as a Word, each Block Element represents 16 bits with their position incrementing 16 by 16. For example, for X0 on a Block Tag with 3 (three) Block Elements, the first Block Element is X0, the second Block Element is X16, and the third Block Element is X32.
