2. The following programming example shows how to convert the data for
temperature input 0 to BCD and store the result in D0 and D1. “0001” is
stored in D1 when the input data is a negative value. The following system
configuration is used.
Temperature unit setting 0 (
°
C)
Two-decimal-place Mode 0 (normal)
Input range setting 1 (Pt100:
