User-Defined Scaling
Your input module was designed to work directly with applications requiring
special data scaling—without an intermediate scaling operation.
Example
. Suppose your input module is in slot 3, and you have a pressure sensor
with a 4–20 mA range connected to channel 0. The following figures show you
how to use the User-Defined Scaling data format to send specially scaled data
(100 to 9999 in this example) to a simple display-only operator interface:
Figure 5-3. User-Defined Scaling Example
Figure 5-4. Programming for User-Defined Scaling Example
Figure 5-5. Data Table for User-Defined Scaling Example
In this example, the operator interface is programmed to read I:3.0 (channel 0
data word).
