When DTM-CT is combined with output status and alarm setting, there are the following distinctions
according to the value written in Hx262:
Set the content of address Hx262 to 0:
According to DTM host or measurement expansion module corresponding to the CT channel, when the
output is on, the CT alarm current value is measured; when the output is off, the CT alarm current value at
the previous turn-on is retained.

Set the content of address Hx262 to 1:
According to DTM host or measurement expansion module corresponding to the CT1 channel, when the
output is on, measure the current value of CT1; when the output is off, measure the current value of CT1.
