plugin	Name of the plugin
config	List of configuration options for the plugin. Multiple lists can be used if needed.

Example

Example 1: Initialize a trendoutput plugin to save the store values of variables "HR" "SP" and "SQI" into the Trends file. This example assumes that the trendoutput plugin is included in the application's PLUGINS file.

(set! store (make-store "store"))
(scheduler-startcase store (time->timestamp (current-time)))
(make-instance store "TRENDOUT" "trendoutput" '("Trends" ("HR" "SP" "SQI")))
(scheduler-init)

Example 2: Create an instance of a trendhistory plugin with two configuration parameters

(make-instance store "TRENDhr" "trendhistory" '("Source" "hr") '("Length" 15))
