How do I change the decimal position in PV and SP in west 6100+ controller? There is a parameter shown in manual for decimal position (dPoS) in configure mode but does not show in display.

The Decimal Position (dPoS) parameter is only available for linear ranges such as 4-20mA. It is not available for temperature ranges. For temperature ranges decimal point position is controlled by the selected range itself.

Example:

Range = JC (Degrees C, Type J, no decimal point)

Range = J.C (Degrees C, Type J, one decimal point)

Most temperature input types can be configured for ranges with 0 or 1 decimal points.
