Retrieving Demand Reporting Information
The values and time stamps in the demand registers are reported in primary amperes. They can be read
from both the HMI and the ASCII command interface.
The values and time stamps can be read from HMI menu Screen 4.4, \REPRT\DEMAND. The values in
the Peak Since Reset registers can be reset by pressing the Reset key. The value in the register will be
set to zero and then updated on the next processing loop with the currently calculated demand value. No
write access is required to do this from the HMI. It is also possible to preset a value into the Peak Since
Reset demand registers. This can be done by pressing the Edit key, changing the preset value using the
scrolling pushbutton keys, exiting and then saving the settings. Write access to the Reports functional
area is required to do this from the HMI.
The values and time stamps in the demand registers can also be read and reset or preset from the ASCII
command interface using the RD (report demands) command.
RD Command
Purpose:
Report all demand data
Syntax: RD
Comments: RD reports Today's Peak, Yesterday's Peak, and Peak Since Reset demand data for all
phase current, neutral current, and negative-sequence current.
RD-P Command
Purpose:
Read/Reset peak demands since reset
Syntax: RD-P[=0]
Comments: A setting of 0 (RD-P=0) resets all the peak demands since reset.
RD-PI Command
Purpose:
Read/Reset peak demand current (I)
Syntax: RD-PI[{p}[=0]] where p=A/B/C/N/Q
Comments: 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.
RD-PI Command Examples:
Example 1. Read the peak demand current for phase B.
>RD-PIB
2.16A 12:14 12/01/05
Example 2. Reset all peak demand current values.
>RD-PI=0
RD-T/Y Commands
Purpose:
Report today's or yesterday’s demands
Syntax: RD-T or RD-Y
Comments: Reports all demands for T (today) or Y (yesterday).
