Use these bits to select the form the analog input data is presented to the controller and used by the controller. The combination of multiple selections in
words and bits determines this value.
For more information on what selections determine the input data form that is used, see Table 21 on page 211

Use these bits to select the input type and operating range for a channel. For more information on what selections determine the input type and
operating range for a channel, see Table 22 on page 211

Data
Value
Channel
x
Use to configure the Alarm Deadband value for a channel. Configuration is done by using words 6, 12, 18, and 24 to set the deadband alarm value.
ETS Use to enable or disable the timestamping function on the module.

n
Use this bit to enable or disable a CJC sensor.
• If enabled, the CJC is read once every other module scan, and its value is updated in the CJC status word. This value is also used for thermocouple cold
junction compensation.
• If disabled, the CJC sensor value is not acquired, and the CJC temperature is fixed at 25 °C (77 °F) for all channels. The CJC is also fixed at 25 °C
(77 °F) for all channels if it is determined to be broken (short or open circuit).
0 = Disable
1 = Enable
Cycle
Calib
Use this bit to enable Cycle Calibration.
• If enabled, the internal calibration of the module occurs once every 5 minutes.
• If disabled, the internal calibration of the module occurs only once at power on/ reset.
Cycle Calibration enables the module to readjust for environmental changes such as variations in temperature. However, the module throughput is
slightly reduced during the calibration operation.
0 = Disable
1 = Enable
