Temperature Sensor Units
Section 7-5
Programming with SCL2(
−
) Instruction
Operation
Two-decimal-place
Mode
If pin 2 on the DIP switch is turned ON, values are stored to two decimal
places. In this case, temperature data is stored as 6-digit signed hexadecimal
(binary) data with 4 digits in the integer portion and 2 digits after the decimal
point. The actual data stored in memory is 100 times the actual value, i.e., the
decimal point is not indicated. Methods for handling this data are described in
this section.
Note
When set to store values to two decimal places, temperature data as far as
two digits after the decimal point is converted to 6-digit binary data, but the
actual resolution is not 0.01
°
C (
°
F). For this reason, there may be skipping
and inaccuracies in the first digit after the decimal point (0.1). Treat any reso-
lution above that specified for the normal data format as reference data.

Execution
condition
Detects an open-circuit alarm.
ON when an open-circuit alarm has
been detected.
Parameter settings for data conversion:
When the converted value is non-
negative, stores #0000 in D00001.
When the converted value is
negative, stores #0001 in D00001.
Detects completion of input 0
initialization.
