Scaling Parameters
The scaling parameters differ depending on the type of function block.
For example, scaling on an AI will be different from scaling on an DI.
For an Analog Input (AI) block, the most important scaling parameters are
as follows.
• L_TYPE —The linearization type used in taking the physical transducer
value to the block output.
• XD_SCALE —Used to take values from the physical transducer for the
I/O channel to a percent of scale. This percent of scale value is called
FIELD_VAL .
• OUT_SCALE —Used in combination with L_TYPE to take the percent of
scale to an output value. This output value is called OUT .
The following diagrams will assist you in determining the parameters you
need to change to obtain the correct scaling for AI, AO, or PID blocks. Each
box indicates the application of the parameter it contains.
