Command Explanations
Command TAR 9 10 is executed in the following example:
=>TAR 9 10 <Enter>
79RS 79CY 79LO SH0 SH1 SH2 SH3 SH4
0 0 1 0 0 1 0 0
0 0 1 0 0 1 0 0

Note that Relay Word bits row 9 is repeated 10 times on the computer display.
In this example, the reclosing relay is in the Lockout State (79LO = logical 1),
and the shot is at shot = 2 (SH2 = logical 1). Correspondingly, the remapped
front-panel targets have the A LED illuminated (corresponding to Relay Word
Bit 79LO in row 9) and the N LED illuminated (corresponding to Relay Word
Bit SH2 in row 9).
TIM Command (Time)
TIM displays the relay clock. To set the clock, type TIM and the desired
setting, then press <Enter>. Separate the hours, minutes, and seconds with
colons, semicolons, spaces, commas, or slashes. To set the clock to 23:30:00,
