Output Items
To read measurement data using the 2533E communication program, the WT110/130 addressable
mode B must be set. Output items do no match those displayed on each display as in the WT110/
130, but match those set for ch.1 to ch.3 in output function setting for the WT110/130. Select
output items according to the 2533E communication programs.
• WT110/130 output items for ch.4 and subsequent ch. nos. are not output.
• For details regarding the setting of output items, refer to page 11-10.
Data Output Format
Data consists of a 12-byte header and 12 bytes of data.
The entire data output format is shown below.
ch.1 header ch.1 data
• Header Section
h1 h2 h3 h4 h5
h1 to h2: Output channel
DA: ch1 DB: ch2
h3 to h4: Data type
1: V (voltage)
2: A (current)
3: W (power)
4: var (reactive power)
5: VA (apparent power)
6 : PF (power factor)
7 : HzV (voltage frequency) 14: Computation result (MATH)*
If "15" is set to h3 and h4 while "DB" is set to h1 and h2, "DB4_" is output to h1 through h4. This is done to
conform to 2533E format.
h5 to h6: Output channel
EA: ch1 EB: ch2
h7: Element
1: element 1 2: element 2
h8: Data state
N: normal I: overrange/no data
h9 to h11: Unit
V_ _ : V VA_: VA
A_ _ : A HZ_ : Hz
W_ _: W Wh_: Wh
VAR: var Ah_ : Ah
*1: CV1, CV2, CV3, CA1, CA2, CA3, A+B, A–B, A * B, A/B, A/2(meaning A/B
