Figure 7.11 SUMMARY Command Example
TARGET Command (Display Relay Word Bit Status)
The TAR command displays the status of front-panel target LEDs or Relay
Word bit, whether these LEDs or Relay Word bits are asserted or deasserted.
The elements are represented as Relay Word bits and are listed in rows of
eight, called Relay Word rows. The first four rows, representing the front-
panel operation and target LEDs, correspond to Table 7.54. All Relay Word
rows are described in Table G.1 and Table G.2.
Relay Word bits are used in SEL
OGIC control equations. See Appendix G:
Relay Word Bits. The TAR command does not remap the front-panel target
LEDs, as is done in some previous SEL relays.

Relay Word Row 0 or last displayed target row.
Adding ROW to the command displays the Relay
Word Row number at the start of each line.
