Temperature Sensor Units
Section 9-5
“m” is the last input word allocated to the CPU Unit, Expansion I/O Unit, or
Expansion Unit connected immediately before the Temperature Sensor Unit.
• Negative values are stored as 2’s complements.
• Data for range codes that include one digit after the decimal point are
stored without the decimal point, i.e., 10 times the actual value is stored.
• If the input temperature exceeds the maximum or minimum value in the
temperature input range that has been set by ±20
°
C or ±20
°
F, the dis-
played value will be held.
• If the circuit is disconnected, the open-circuit detection function will oper-
ate and the converted temperature data will be set to 7FFF.
• The open-circuit detection function will be automatically cleared and nor-
mal input temperature conversion will begin automatically when the input
temperature returns to the convertible range.
Startup Operation
After power is turned ON, approximately 1 s is required for the first conversion
data to be stored in the input word. During that period, the data will be 7FFE.
Therefore, create a program as shown below, so that when operation begins
simultaneously with startup it will wait for valid conversion data.
Handling Unit Errors
• CP-series Expansion Unit/Expansion I/O Unit errors are output to bits 0 to
5 of word A436. The bits are allocated from A436.00 in order starting from
the Unit nearest the CPU Unit. CP1W-TS002 and CP1W-TS102 Temper-
ature Sensor Units are allocated two bits each. Use these flags in the pro-
gram when it is necessary to detect Expansion Unit/Expansion I/O Unit
errors.
• When an error occurs, the Temperature Sensor Unit data becomes 7FFF
hex (the same as for an open-circuit detection). With an open-circuit
detection, it is not reflected in word A436.
