I/O Block Elements represent links for every position in a Block to use as if they were I/O Tags. Block Elements can freely point to each index inside a Block. There can be two Block Elements pointing to the same index in a Block, and also to more, less, or the same number of Elements as the number of variables declared in a Block. To use this resource, follow this procedure:

1.Right-click an I/O Block and select the Insert - I/O Element option.

Inserting an I/O Block Element

In case of a device used to collect data informs Tag values that need to be converted, users can use Tag scales, which are basically a specification of a linear conversion between two different bases.

To do so, users must enable Element's EnableScaling property and inform DeviceLow and DeviceHigh parameters (via their respective properties), which are respectively low and high limits of device's data, and also inform EULow and EUHigh parameters (via their respective properties), which are low and high data limits, in engineering units.

Some of this object properties can be configured directly on Properties List, without creating scripts for this. More information on this object's properties functionality can be found on E3 Reference and Scripts Manual , in its respective chapter.
