Choose a Data Format Data format determines how the data is returned from the module to the
owner-controller and the features that are available to your application. You
choose a data format when you choose a
Communication Format .
You can choose one of these data formats:
• Integer mode
• Floating point mode
The table shows features that are available in each format.
For more information on input and output data formats, see page 205
in Chapter 10 .
Data Format Features Available: Features Not Available
Integer mode Multiple input ranges
Notch filter
Real time sampling
Cold junction temperature is
on 1756-IT6I and 1756-IT6I2
modules only
Temperature linearization
Process alarms
Digital filtering
Rate alarms
Floating point mode All features N/A
IMPORTANT
Integer mode does not support temperature conversion on
temperature-measuring modules. If you choose integer mode,
the 1756-IR6I is strictly an ohms (
Ω ) module and the
1756-IT6I and 1756-IT6I2 are strictly millivolts (mV) modules.
