9328900990 Rev L BE1-951 Reporting and Alarm Functions 6-9
RD Command
Purpose: Report all demand data (peak, today and yesterday).
Syntax: RD
Comments: RD reports Today's Peak, Yesterday's Peak and Peak Since Reset demand data for all
phase current, neutral current, negative-sequence current, three-phase reactive power,
and three-phase power. Vars are expressed as lagging values (+) or leading values (–).
Peak var (RD-TVAR, RD-YVAR and RD-PVAR) values and peak watt (RD-TWATT, RD-
YWATT and RD-PWATT) values are reported as two parameters. The first value is the
peak positive demand; the second value is the peak negative demand.
RD Command Example:
Example 1. Read all demand register data.

Demand information specific to current, vars, or watts can be obtained by including an object name with
the command function (R) and subgroup (D). Today's Peak, Yesterday's Peak, and Peak Since reset
information for current is available using the RD-TI, RD-YI, and RD-PI commands.
RD-TI/YI Command
Purpose: Reads Today's Peak (TI) or Yesterday's Peak (YI) Demand current values.
Syntax: RD-TI<x> or RD-YI<x>
Comments: x = A/ B/ C/ N/ Q, where A, B, and C represent A, B and C-phase; N represents neutral;
and Q represents negative-sequence.
RD-TI and RD-YI Command Examples:
Example 1. Read today's C-phase ampere demand current.
>RD-TIC
0.00A 09:13 07/22/05
Example 2. Read all demand current values for yesterday.
>RD-YI
RD-YIA:0.00A 00:51 07/21/05; RD-YIB:0.00A 00:51 07/21/05
RD-YIC:0.00A 00:51 07/21/05; RD-YIN:0.00A 00:51 07/21/05
RD-YIQ:0.02A 00:07 07/21/05
RD-PI Command
Purpose: Read/Reset the peak demand current values.
Syntax: RD-PI<x>[=0]
Comments: x =A/B/C/N/Q, where A, B, and C represent A, B and C-phase, N represents neutral and
Q represents negative-sequence. A setting of 0 (RD-PI<p>=0) resets the peak demand
values.
