Temperature-measuring Analog Modules (1756-IR6I, 1756-IT6I, and 1756-IT6I2) Chapter 6
When you select any of the sensor or thermocouple types (listed in the table)
during configuration, RSLogix 5000 software uses the default values in the
scaling box.
The table displays the temperature range for each 1756-IR6I sensor type.
To see how to choose an RTD sensor type, see page 215 .
The table displays the temperature range for each 1756-IT6I
and 1756-IT6I2 sensor type.
Default Signal and Engineering Values in RSLogix 5000
1756-IR6I 1756-IT6I and 1756-IT6I2
Low signal = 1 Low engineering = 1 Low signal = -12 Low engineering = -12
High signal = 487 High engineering = 487 High signal = 78 High engineering = 78
IMPORTANT
The module sends back temperature values over the entire
sensor range as long as the low signal value equals the low
engineering value and the high signal value equals the high
engineering value. The actual numbers used in the signal and
engineering fields are irrelevant as long as they are equal.
