These names are listed in the Relay Word Bits table in Section 9: Setting the
Relay.
A typical HEX-ASCII Relay Word is shown below:
10000004924900000000000000000000000000000200000000000000000000
0000280000800000800000000000000000000000000000000000001F0000
Each bit in the HEX-ASCII Relay Word reflects the status of a Relay Word bit.
The order of the labels in the "Names of elements in the relay word separated
by spaces" field matches the order of the HEX-ASCII Relay Word. In the
example above, the first two bytes in the HEX-ASCII Relay Word are “10.” In
binary, this evaluates to 00010000. Mapping the labels to the bits yields:
In this example, the 50A2 element is asserted (logical 1); all others are
deasserted (logical 0).
