Module Data, Status, and Channel
Configuration
After installing the 1769-IT6 thermocouple/mV input module, you must
configure it for operation, usually by using the programming software compatible
with the controller (for example, RSLogix 500 or RSLogix 5000 software).
Once configuration is complete and reflected in the ladder logic, you need to
operate the module and verify its configuration.
This chapter contains information on the following:
• Module memory map
• Accessing input image file data
• Configuring channels
• Determining effective resolution and range
• Determining module update time
