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.

1000.00 ON when input 0 has been initialized
CMP(020) Detects completion of input 1 initialization.

#7FFE
1000.01 ON when input 1 has been initialized
CMP(020)
Detects an open-circuit alarm or Unit
error by checking converted temperature

data for the error code 7FFF.
#7FFF
ON when an open-circuit alarm or Unit
100.00
error has been detected for input 0.
CMP(020) Checks to see if the temperature data
in word 2 has exceeded 500.0°C (1388

hex without decimal point).
#1388
100.01 ON for an input 0 temperature error
BCD(024) Converts the temperature data for
input 0 to BCD and stores the result in
