Configuring a 1769-IT6
Thermocouple Module To configure the 1769-IT6 module in slot 1, click the plus sign left of Local:1:C.
Configuration data is entered under the Local:1:C.Data tag. Click the plus sign
to the left of Local:1:C.Data to reveal the eight integer data words where
configuration data may be entered for the 1769-IT6 module. The tag addresses
for these eight words are Local:1:C.Data[0] through Local:1:C.Data[7].
Only the first seven words of the configuration file apply. The last word must
exist but should contain a value of 0 decimal.
The first 6 configuration words, 0…5, apply to 1769-IT6 channels 0…5
respectively. All six words configure the same parameters for the six different
channels. The seventh configuration word is used for enabling or disabling cyclic
calibration. The following table shows the various parameters to configure in
each channel configuration word. For a complete description of each of these
parameters and the choices available for each of them, see
Configuration Data
File on page 41 .
Once you have entered your configuration selections for each channel, enter your
program logic, save your project, and download it to your CompactLogix
controller. Your module configuration data is downloaded to your I/O modules
at this time. Your 1769-IT6 module input data is located in the following tag
addresses when the controller is in Run mode.
