G. CT current value when output is ON or OFF: (communication addresses are shown in the table
below)
Read the current value of the corresponding channel according to the internal station number of
DTM-CT030. The user can decide to read the value when the output is on or off.
Want to read the CT value when output is ON: First set the content of communication address
Hx262 as 0, and then read Hy2C0~Hy2C7 to obtain the CT value when output is ON
Reading the CT value when output is OFF: First set the content of communication address
Hx262 as 1, and then read Hy2C0~Hy2C7 to obtain the CT value when output is OFF

Table - Communication address for reading the CT current in accordance with DTM-CT030
Notes:
1. Notes: x is the internal station number of the DTM host or measurement expansion module
corresponding to the CT.
2. y is the internal station number of the DTM-CT030.
3. When reading the CT value with output [OFF], if the output changes to [ON], the communications
content will still preserve the original CT current value when [OFF], and the CT value will not be
refreshed until output again changes to [OFF], and vice versa.
4. CT time-division reading measurement and CT full-time measurement can only be measured
for CT1. In order to synchronize the display time of the CT measurement current value with
the ON time of the output channel, it is recommended that the CT1 measurement channel be
assigned to the expansion cassette output on the DTM host or measurement expansion
module. If the output ON time is too small, the full-time measured CT current value display
will not be synchronized with the output status.
