Setpoint Programmer Pre-Plot Graph attributes
1. The content of the pre-plot graph is determined by reading the profile content of the Setpoint
Programmer function block. Time is presented on the X axis and the SP value is presented on the Y
axis of the graph.
2. The amount of time contained within the pre-plot graph is determined by:
a) The number of user programmed segments in the profile (The user may use from 2 to 50 of the
available segments for his program.)
b) The time units specified for the profile (minutes or hours)
