DISPFLD
Custom Mode Display Field Command
Input
DISPFLD <field>,<source>,<units>[term]
Format
n,n,n
<field>
Specifies field (display location) to configure: 1–4.
<source>
Specifies item to display in the field: 0 = None, 1 = Input A,
2 = Input B, 3 = Setpoint 1, 4 = Setpoint 2, 5=Output 1, 6=Output 2
<units>
Valid entries: 1 = kelvin, 2 = Celsius, 3 = sensor units,
4 = minimum data, 5 = maximum data, 6 = sensor name.
Example
DISPFLD 2,1,1[term]
displays kelvin reading for Input A in display field 2 when dis-
play mode is set to Custom.
Remarks
Since each display field is only ten characters, only the first nine characters of the sen-
sor name will be displayed when the units for a field are set to display the sensor
name. However, if two adjacent fields are assigned to the same sensor name, then the
entire twenty character line can be used, allowing all fifteen sensor name characters
to be displayed.
This command only applies to the readings displayed in the Custom display mode. All
other display modes have predefined readings in predefined locations, and will use
the Preferred Units parameter to determine which units to display for each sensor
input. Refer to section 4.3 for details on display setup
