Section 5.2
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).
