\Paused

A tag value of 1 pauses the trend.

A tag value of 0 resumes movement of the trend.

For real-time trends, RSView32 reads the value of this tag
when the trend is first displayed to determine whether to
start the trend in paused or resumed mode. If this tag
doesn’t exist, the trend is started in resumed mode.

For historical trends, RSView32 reads the value of this tag
when the trend is first displayed to determine whether to
start the trend in paused or resumed mode. If this tag
doesn’t exist, the trend is started in paused mode.

File-based trends are always started in paused mode.
