Entering a setpoint in a display
A text can contain two values such as actual values and
setpoints of function relays, analog input values and time
and date. The position of setpoints and actual values is fixed
to the centre of lines 2 and 3. The length depends on the
value to be displayed. Setpoint entries in the text display are
useful if the PARAMETER menu is not available for display or
entry. Also when the operator is to be shown which setpoint
is being modified.
The example shows the following.
The setpoint of timing relay T1 is to be changed from 12
minutes to 15 minutes.
• Line 2: setpoint of timing relay T1, can be edited.
• Line 3: actual value of timing relay T1.
The text is displayed.
Line 1
Line 2, setpoint can be edited
Line 3, setpoint can be edited
Line 4
h
The appropriate text function block must be available in
order to modify a setpoint. The setpoint must be a
constant.
h
When values are being entered, the text is retained
statically on the display. The actual values are updated.
