CSV_TrendX_ClearTrend

Clears trend cache and delete trend file associated with specified trend.

This function needs to be called before a new variable can be assigned to a Instant Trend tag. This needs to be done as the trend tag may have been previously assigned to a different variable, in which case scrolling back through the trends history could display data not associated with the current variable.

Note: This function is to be called only on a Trends Server. To maintain redundancy the function is also called with the same arguments on the second/redundant Trends Server.

• 1 = update second Trends Server with same info; i.e., RPC same function on second Trends Server.
