Description of Commands
If you attempt to acknowledge an event summary that you have not viewed on
the present port with the SUM NEXT command, the relay responds,
Event
summary number n has not been viewed with the NEXT option
.
SUM NEXT
Use the SUM N command to view the oldest (next) unacknowledged event
summary.
TARGET
The TA RGET command displays the elements for a selected row in the Relay
Word bit table (see Appendix A: Relay Word Bits).
TAR
Use the TAR command to view a row of Relay Word bit elements or aliases.
When using the TAR command, you can specify the row number or element
name.
The relay memorizes the latest target row input conditioned by your present
access level. The relay displays Row 0 if you have not specified a row since
power up, the access level has timed out, or you have issued the QUIT
command.
If you specify the repeat count k at a number greater than 8, the relay displays
the repeated target rows on the terminal screen in groups of eight, with the
target row elements listed above each grouping.
