9. TEMPERATURE INPUT MODULE CONNECTIONS B-61813E/03
−106−
DI05 : System error--the internal circuit is abnormal.
DI06 : Wrong module--other than the correct module has been
installed.
2) Status signals, CH2 temperature data, CH4 temperature data, or
abnormality data
DI23 DI22 DI21 DI20 DI19 DI18 DI17 DI16
DI31 DI30 DI29 DI28 DI27 DI26 DI25 DI24
• Status signals
DI129 : Abnormality sign bit
1 : This bit becomes "1" when the temperature
input becomes abnormal. DI16 to DI28 are
used to describe the abnormality.
0 : DI16 to DI28 are used to indicate the
temperature data.
DI30 : CH2 data READY
1 : Read the CH2 temperature data from DI16
to DI28 when this bit is set to "1".
DI31 : CH4 data READY
1 : Read the CH4 temperature data from DI16
to DI28 when this bit is set to "1".
• CH2 temperature data, CH4 temperature data, or
abnormality data
DI16 (LSB) to DI28 (MSB):
These bits indicate temperature input data
(CH2/CH4) or abnormality data.
Temperature input data
The temperature input data is in binary. It is ten times the actual
temperature.
Example
(41F3h → 0499 → 49.9℃)
The highest three bits are status signals.
For a thermoresistance-type module (ATI04A), the DI28 bit is a sign
bit. (Negative data is represented in two's complement.)
Example
(5FFBh → -0.5℃)
The highest three bits are status signals.
