The Attribute Tag is usually used to display the value of one Tag, but have a second tag control the color (either Alarm Color, Discrete Color or Multi-State color).
An example is if there is a separate alarm tag and value.
For example a tag like LSBE8_VFD_ALM shows the alarm state of LSBE8 VFD (Variable Speed Drive).
There are three other tags associated with LSBE8 VFD:
If you use LSBE8_VFD_ALM as the attribute tag for LSBE8_S_S, LSBE8_SPD and LSBE8_DP for Alarm State, then those three tags will flash red (or whatever color) when LSBE8_VFD_ALM is in alarm (but only if LSBE8_VFD_ALM is in alarm).
Other possible uses are to have one tag control movement, rotation, size, and a second tag control alarm color, digital color, multi-state color or even multistate text.

1. Click once on the object to be animated.
