5.10. Scaling an analog value
5.10.1. Using the potentiometers of the 40 and 50 series
The 40 and 50 series central units each have two potentiometers, which allow the adjustment
of parameters without a programming tool.
 The MULDI function block may be used for scaling.
The desired setting range in this example is from 0 to 30 000:
Setting range Value read in the
central unit
30000 150
yx
00
The value y set is such that: y = (30 000 * x) / 150. The result y is placed in the variable
MW 000.00.
