Trend Recorder A Trend Recorder provides a continuous, time-based charting of the value of a
variable or direct address in a PLC. A Trend Recorder emulates a strip-chart
recorder, with the pen on the right, and the “paper” moving from right to left. A
vertical scale can be shown on the left side of the chart for showing the range of the
value being recorded, and a horizontal scale can be shown below the chart for
showing the time span of the chart. The rate at which the chart is updated, and the
appearance of the chart can be set.
