…Display
Chart View  Enables the operator level chart function to be configured.
The chart can display the trend for 1 or 2 analog values and be scaled independently
of the engineering ranges for the analog values selected.
Note. Enabled only if Operator Template, Chart is selected – see page 37.
Channel 1 (2)
Source Selects the analog value to be shown on the chart – see Appendix A.2, page 105
for details of analog sources.
Scale Low* Sets the minimum value on the y-axis for this channel.
Scale High* Sets the maximum value on the y-axis for this channel.
Tag A 3-character, alphanumeric tag used to identify the parameter on the chart.
Sample Rate Selected from 1, 10, 30 seconds; 1, 2, 3, 4, 5 minutes.
Settings Adjusts display settings to suit ambient conditions.
Brightness Increases / Decreases the display brightness to suit local environmental conditions.
Contrast Increases / Decreases the display contrast to suit local environmental conditions
(enabled for CM30 and CM50 only).
Date & Time  Sets the date format, local time / date and daylight saving start / end times.
Date Format Selected from: DD–MM–YYYY, MM–DD–YYYY, YYYY–MM–DD.
Time & Date Sets the controller's time and date.

The day within the month that daylight starts / ends – for example, to set daylight
saving to start (or end) on the second Monday of the selected month, select Second.
DS Start Day
DS End Day

for the selected day.
DS Start Month
DS End Month
The month daylight saving starts / ends.
*When the controller is setup for the first time, the Scale Low and Scale High values default to match the engineering range.
