Appendix 1.3 For Users Using Communication Commands of Digital Power Meter 2533E
Appendix 1.3 For Users Using Communication
The WT110/130 differ from the 2533E in communication commands and data format. The
WT110/130 has a function which enables the user to use communication programs created for the
2533E. This function is described below.
Communication Commands
Under usual conditions, the 2533E commands cannot be used. The "CM" command should be set
to CM2 to be able to use the 2533E commands (for details about the CM command, refer to
Appendix 2).
Description is given below in alphabetical order of those commands which differ from the
WT110/130 when the 2533E group is selected.
Note
• For addressable mode setting method, refer to section 11-1, page 11-9.
• WT110/130 code format is used for error code and status byte. For details, refer to page 11-3 and 14-3. The
• To read harmonic analysis data via RS-232-C interface, select a value other than "0" for handshake mode
DS
Sets the delimiter EOI output timing.
This command is used with the 2533E, but
cannot be used with the WT110/130 even
if the 2533E group is selected by the "CM"
command.
MN/MN?
Sets the measurement mode/inquires
about the current setting.
Syntax
MNm <terminator>
m stands for measurement mode.
m=0 : RMS
1 : V MEAN
2 : DC
Query
MN? <terminator>
Example
MN0
Description
Parameter error 12 will occur if "m" is set to an
illegal value.
OL
Requests output of setting
parameters. Output format differs from
that of the 2533E
Syntax
OL <terminator>
Example
MODEL253503<terminator>
RV9;AV1<terminator>
RV9;AA1;SA50.00<terminator>
DA1;DB2;DC3<terminator>
EA1;EB1;EC1<terminator>
WR3;FL0;SC0;AG0;HD0;MT0<terminator>
MN0<terminator>
KV1.000;KA1.000;KW1.000<terminator>
AT1;AC1<terminator>
IC0;TM0,0<terminator>
SO0;SR0,0,0;RO0;RR0,0,0<terminator>
PS1;HA0;OR1;HE1;DF0<terminator>
RT1,0<terminator>
YO0;YM1;DY0;YC1<terminator>
CM2<terminator>
END<terminator>
Description
When the external sensor scaling values and P/C/
F scaling values set for each element differ from
each other, the value set for element 1 will be
output.
IM 253401-01E
Commands of Digital Power Meter 2533E
WT110/130 code format differs from 2533E code format.
since harmonics analysis data consists of a number of output bytes.
OS
Requests output of setting
parameters. This command cannot be
used if 2533E command group is selected
by the "CM" command. However, in this
case the "OL" command can be used
instead.
WR/WR?
Sets the wiring system/inquires
about the current setting.
Syntax
WRm <terminator>
m stands for wiring system.
m=0 : 3Φ3W (for 253502, 253503 only)
1 : 3Φ4W (for 253503 only)
3 : 1Φ3W (for 253502, 253503 only)
4 : 3V3A (for 253503 only)
Query
WR? <terminator>
Example
WR0
Description
Parameter error 12 will occur if "m" is set to an
illegal value.
