Configure
the Process Tag properties by double-clicking on the tag the data
grid and selecting the Properties tab. The standard VB style properties grid is used.
Select a field to display a descriptive comment at the bottom of the
form. When changing
properties the entry is committed to the object immediately when the cursor leaves
the field. There is no cancel operation.
Name
- Use to assign a meaningful name to the tag. The name is used
to identify tags in the data grid displays.
Description - Addition information can be stored with the tags
using the Description field.
Enabled - Controls whether the Process Tag receives Updated
events from it's source tag.
Parent
- The name of the parent object of this tag. Normally this is a
Process Tag Group.
BufferSize - Sets the buffer size for storing and viewing data
samples. The range is limited to 1-1000 samples.
Scaling
- Set this to true to begin scaling. Scaled Process Tags will always be converted to System.Double data
types. Scaling is ignored on types that can't be scaled such as
strings or date/time values.
HighRaw
- Defines the expected upper range of the source tag.
LowRaw
- Define the expected lower range of the
source tag.
HighRange
- Defines the desired upper range of the resulting scaled value.
LowRange
- Defines the desired lower range of the resulting scaled value.
Clamping
- Set to true to insure that the value
does not go outside this range and that any value written to the
source tag does not go outside of the defined raw range.
SquareRootScaling
- Set to true to select square root scaling instead of the default linear
method.
Masking
- Set this to true to begin masking. You can enter a mask that will be applied to the integral source tag
when the data sample arrives at the Process Tag. Masking is ignored if
the source tag is not an integral type.
Mask
- The bits set in the mask
indicate the bits used (AND'ed). The value will be shifted to
the proper weight. Masking is applied on reads and in reverse on
writes. Use any radix format such as
2#0000,1111
or 16#00ff,fff0
or any decimal number like
65520.
NOTE: You
may combine scaling and masking.
Source

the browse button in the SourceTag field.

the Tag Server to select a
new Source Tag.
