(b) The following programming example shows how to convert the data for tempera-
ture 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.

ON when an open-circuit alarm or Unit
error has been detected for input 0.
Stores positive BCD data in D0.
Stores #0000 in D1.
When input 0 converted value is negative
(#0000 minus two’s complement = actual
value)
Stores negative BCD data in D0.
Stores #0001 in D1 to indicate a
negative number.
