Module Data, Status, and Channel
Configuration

After installation of the 1769-IR6 RTD/resistance input module, you must
configure it for operation, usually using the programming software compatible
with the controller (for example, RSLogix 500™ or RSLogix 5000™). Once
configuration is complete and reflected in ladder logic, you will need to get the
module up and running and then verify its operation. This chapter includes
information on the following:

·

module memory map

·

accessing input image file data

·

configuring channels

·

configuring periodic calibration

·

preparing ladder logic to reflect the configuration

·

running the module

·

verifying the configuration
